Influence of Seed Size, Testa Color, Scarification Method, and Immersion in Cool Or Hot Water on Germination of Baptisia Austral
HORTSCIENCE 40(6):1846–1849. 2005. Seeds were cleaned and separated into two size fractions using U.S. standard test sieves. For the large-seeded fraction, 100% of the Infl uence of Seed Size, Testa Color, seeds passed through a No. 6 sieve (3.35 mm nominal opening) and 100% were retained on Scarifi cation Method, and Immersion a No. 8 sieve (2.36 mm nomimal opening). For the small-seeded fraction, 100% of the in Cool or Hot Water on Germination seeds passed through a No. 8 sieve and 100% were retained on a No. 10 sieve (2.00 mm nominal opening).

Variation in the Grass Pea (Lathyrus Sa Tivus L.' and Wild Species
Euphytica 33 (1984) 549-559 VARIATION IN THE GRASS PEA (LATHYRUS SA TIVUS L.' AND WILD SPECIES M. T. JACKSON and A. G. YUNUS1 Department of Plant Biology, University of Birmingham, Bl5 2Tr, England Received 21 September 1983 .DEX WORDS Lathyrus sativus,grass pea, wild species,variation, multivariate analyses. SUMMARY Forty-nine accessionsof Lathyrus sativuswere studied for morphological variation. Data were analysed using Principal Components Analysis and Cluster Analysis. The variation in 14 speciesof SectionLathyrus was also evaluated in order to ascertainaffinities betweenL. sativusand other species. L. sativus is a highly variable species,and there is a clear distinction betweenthe blue-flowered fonns from south-west Asia, Ethiopia and the Indian subcontinent, and the white and white and blue flowered fonns with white seedswhich have a more westerly distribution. Differences in vegetative parts may be due to selectionfor forage types. L. sativus appears to be closely related to L. cicera and L. gorgoni, and this relationship needs further investigation. INTRODUCTION The genus Lathyrus is large with 187 speciesand subspeciesrecognised (ALLKIN et al., 1983).Species are found in the Old World and the New World, but clearly there are centres of diversity for Old World speciesin Asia Minor and the Mediterranean region (ZEVEN& DE WET,1982). A number of speciesare usedas animal fodder plants including L. hirsutusand L. palustris, and some are valued as ornamentals, especially L. odoratus,the sweetpea. Only one species,L. sativus,the grasspea, khesari or chick- ling pea is widely cultivated as a food crop, and this pulse is a dependable cropper in drought conditions (SMARTT,1976). -
The Genus Baptisia in Alabama
Woods, M. and A.R. Diamond, Jr. 2014. The genus Baptisia in Alabama. Phytoneuron 2014-83: 1–11. Published 12 August 2014. ISSN 2153 733X THE GENUS BAPTISIA (FABACEAE) IN ALABAMA MICHAEL WOODS [email protected] ALVIN R. DIAMOND , JR. Department of Biological and Environmental Sciences Troy University Troy, Alabama 36082 ABSTRACT The primary objectives of this project were to determine which species of Baptisia (Fabaceae) occur in Alabama and to report the county distribution of each. Baptisia , known commonly as wild or false indigo, is recognized as consisting of seven species in Alabama. The most common species are Baptisia alba, B. bracteata, and B. megacarpa. The less common species are B. lanceolata and B. albescens . The least common species are B. australis and B. perfoliata. The dichotomous key and descriptions we present are modifications from earlier authors; however, all measurements are based on morphological features of the vegetative and reproductive structures of the more than 200 specimens studied during this project. Data for the county-level distribution maps were compiled entirely from herbarium vouchers. Baptisia , commonly known as wild or false indigo, consists of 18 species, 7 infraspecific taxa, and 6 hybrids confined to the eastern USA and Canada (NatureServe 2013). Of these, 15 species have been reported from the southeastern USA (Isely 1990) and eight species and one infraspecific taxon have been reported from Alabama (Kral et al. 2011). The genus Baptisia Vent. is a member of the legume family Fabaceae (Leguminosae), tribe Thermopsideae, which includes six genera and approximately 45 species scattered through the Mediterranean and eastern North America (Turner 1981). -
Diseases of Specific Florist Crops Geranium (Pelargonium Hortorum)
Diseases of Specific Florist Crops Keeping florist crops free of disease requires constant care and planning. Prevention is the basis of freedom from disease and should be an integral part of the general cultural program. The symptoms of the diseases of major florist crops are described individually by crop in a series of fact sheets. Geranium (Pelargonium hortorum) • Bacterial blight (Xanthomonas campestris pv. pelargonii): Tiny (1/16 in. diameter) round brown leaf spots, often surrounded by a chlorotic zone. Spots form when bacteria have been splashed onto the leaf surface. Subsequent systemic invasion of the plant leads to the development of a yellow or tan wedge-shaped area at the leaf edge and then to wilting of the leaf. Further progression of the disease may lead to brown stem cankers at nodes, brown to black vascular discoloration inside the stem, and tip dieback or wilting of all or part of the plant. Roots usually remain healthy-looking. Disease symptoms develop most readily under warm (spring) greenhouse temperatures. Spread is rapid during the handling and overhead irrigation associated with propagation. Only geraniums are susceptible to bacterial blight. P. hortorum (zonal) and P. peltatum (ivy) both show symptoms; P. domesticum (Martha Washington or Regal) is less likely to show symptoms. Hardy Geranium species may also be a source of infection; these will show leaf spot but not wilt symptoms. Infested plants should be destroyed; there are no chemical controls. Although culture- indexing procedures should have eliminated this disease from modern geranium production, it remains all too common in the industry today, causing large financial losses to geranium growers. -

Baptisia australis has blue flowers and is known as blue indigo, and Baptisia tinctoria has yellow flowers and is known as wild indigo. In garden centers, many cultivars of B. australis are available including ‘Cherries Jubilee’ which has yellow and pink bicolored flowers and ‘Carolina Moonlight' which has soft yellow flowers. Baptisia can get 3-5 feet tall and does best in full sun to partial shade. Above right- B. australis 'Cherries Jubilee' Baptisia Mountain Laurel Mountain laurel, Kalmia latifolia, the state flower of Connecticut, is native throughout eastern North America and occurs in the understory of a variety of habitat types and plant communities. In Connecticut it can commonly be found in mixed hardwood forests and in communities of white pines. There are many cultivars for landscape use including 'Bull's Eye', shown above. 'Sarah' (left) has red flower buds that open to bright pink flowers. Right- an unknown cultivar of pink mountain laurel. Mountain Laurel Tulip Tree Liriodendron tulipifera, or yellow poplar, is one of North America’s tallest native deciduous tree. It’s common name refers to its large, upright tulip-like flowers that bloom in spring. Flowers are yellow and have an orange band at the base of each petal, and they appear after leaves are fully open. Leaves are 4-lobed, large and somewhat flattened at the top. It is native in Connecticut appearing in localized areas in the wild. -
PHASEOLUS LESSON ONE PHASEOLUS and the FABACEAE INTRODUCTION to the FABACEAE
1 PHASEOLUS LESSON ONE PHASEOLUS and the FABACEAE In this lesson we will begin our study of the GENUS Phaseolus, a member of the Fabaceae family. The Fabaceae are also known as the Legume Family. We will learn about this family, the Fabaceae and some of the other LEGUMES. When we study about the GENUS and family a plant belongs to, we are studying its TAXONOMY. For this lesson to be complete you must: ___________ do everything in bold print; ___________ answer the questions at the end of the lesson; ___________ complete the world map at the end of the lesson; ___________ complete the table at the end of the lesson; ___________ learn to identify the different members of the Fabaceae (use the study materials at www.geauga4h.org); and ___________ complete one of the projects at the end of the lesson. Parts of the lesson are in underlined and/or in a different print. Younger members can ignore these parts. WORDS PRINTED IN ALL CAPITAL LETTERS may be new vocabulary words. For help, see the glossary at the end of the lesson. INTRODUCTION TO THE FABACEAE The genus Phaseolus is part of the Fabaceae, or the Pea or Legume Family. This family is also known as the Leguminosae. TAXONOMISTS have different opinions on naming the family and how to treat the family. Members of the Fabaceae are HERBS, SHRUBS and TREES. Most of the members have alternate compound leaves. The FRUIT is usually a LEGUME, also called a pod. Members of the Fabaceae are often called LEGUMES. Legume crops like chickpeas, dry beans, dry peas, faba beans, lentils and lupine commonly have root nodules inhabited by beneficial bacteria called rhizobia. -
Sweet Pea Cut Flower Production in Utah Maegen Lewis, Melanie Stock, Tiffany Maughan, Dan Drost, Brent Black

This high tunnels. Sweet peas should be transplanted makes very early spring planting challenging and early in the spring and harvested until hot summer increases the risk of disease. temperatures decrease stem length and quality. Sweet peas require a strong trellis, high soil fertility, and frequent harvesting. Tunnel-grown sweet peas began producing 4 weeks earlier and had 15% more marketable stems than a field-grown comparison crop in North Logan, Utah. However, our hot, semi- arid climate, combined with insect pressure limited success in our trials. How to Grow Soil Preparation: For optimal growth, sweet peas require rich, well-drained soil. Incorporating an inch of compost into the soil prior to planting can increase fertility, drainage, and organic matter, without creating pH or salinity problems. Conduct a routine soil test to determine any soil nutrient needs prior to planting sweet peas. Soil testing is particularly important when planting in new locations, and should be repeated every 2 years. USU’s Analytical Laboratories performs soil tests. Pricing and information for collecting and submitting a sample is available on their website.

Growing Fabulous Sweet Peas
Growing Fabulous Sweet Peas (Lathryrus Odoratus) What? Family: Papilionaceae (think “butterfly”) Genus: Lathyrus Odoratus (simply put, “fragrant and very exciting”) Species: Latifolius (loosely, a ”broad flower”) Botanist Credited: Theophrastus, a Greek philosopher, student of Aristotle Varieties: There are about 150 species of the Lathyrus genus. At one time there were about 300 hundred varieties but now, unfortunately, only about 50 are available. In other words...our exquisite sweet peas are “broad, exciting, butterfly-shaped flowers!” Although stories vary about its European history, the lovely sweet pea is thought to have been brought to Britain via a Sicilian monk who sent seeds to a Middlesex schoolmaster, Henry Eckford in the 19th century. Over a period of more than 30 years, Eckford crossed and selected sweet peas to produce large flowers (grandifolia). The Spencer family (of the Princess Di fame) later developed many of the varieties, in the Earl of Spencer’s garden at Althorp, Northamptonshire, the best known being the ‘Countess Spencer’. The varieties we see today which sport the Spencer name are descended from the Earl’s own gardens! The English are crazy about sweet peas, their “poor man’s orchids.” Long before our Bozeman Sweet Pea Festival was a seed in our pea-pickin’ brains, a 1911 London sweet pea contest boasted over 10,000 entries! If you spend any time on the internet researching sweet peas, you will observe that most of the in-depth information about sweet peas originates from Great Britain. As a matter of fact, the sweet pea wound itself so tightly around British culture that you will find sweet peas in a number of extremely collectible china patterns (particularly the Royal Winston), in prints and paintings, and, of course, in gardens everywhere. -
Best Plants for Problem Clay Soils: Perennials
Visit us on the Web: www.gardeninghelp.org Best Plants for Problem Clay Soils: Perennials Perennials Amsonia tabernaemontana — Bluestar This Missouri native features uptight clusters of light blue star-like flowers in late spring. Its narrow willow-like leaves turn yellow to peach-colored in fall. Bluestar may require staking if grown in shade and may be pruned after flowering to maintain a compact shape. It is most attractive when grown massed, in native plant gardens, shade gardens, open woodland areas, and borders. Asclepias incarnata — Swamp milkweed Despite its common name and native habitat, swamp milkweed may be grown in the average garden. Its fragrant white, pink or mauve flowers attract butterflies and mature into slender pods with silky-haired seeds. Swamp milkweed is a good choice for sunny, low or moist areas such as stream or pond banks, borders, and butterfly gardens. Baptisia australis — Blue false indigo Blue false indigo has beautiful purplish blue lupine-like flowers borne in erect spikes above the trifoliate leaves. The flowers mature into black seed pods that rattle in the breeze and are an interesting addition to dried flower arrangements. This herbaceous perennial does best in full sun as plants grown in part shade may grow taller and need support. Due to an extensive root system, blue false indigo will tolerate drought, but it should not be disturbed once it is established. Attractive in almost any situation including borders, prairies, cottage gardens, and native plant gardens, this plant is best used as a single specimen plant or in small groups. Baptisia australis var. -

Temperate-adapted perennial grain legumes, though currently non-existent, might be uniquely situated as crop plants able to provide relief from reliance on synthetic nitrogen while supplying stable yields of highly nutritious seeds in low-input agricultural ecosystems. As such, perennial grain legume breeding and domestication programs are being initiated at The Land Institute (Salina, KS, USA) and elsewhere. This review aims to facilitate the development of those programs by providing criteria for evaluating potential species and in choosing candidates most likely to be domesticated and adopted as herbaceous, perennial, temperate-adapted grain legumes. We outline specific morphological and ecophysiological traits that may influence each candidate’s agronomic potential, the quality of its seeds and the ecosystem services it can provide. -
