AGAVE Agave Americana Characteristics Culture Noteworthy

AGAVE Agave Americana Characteristics Type: Succulent Water: Dry to medium Zone: 8 to 10 Maintenance: Medium Height: 3.00 to 6.00 feet Flower: Showy Spread: 6.00 to 10.00 feet Leaf: Evergreen Bloom Time: Rarely flowers Other: Winter Interest Bloom Description: Greenish yellow Tolerate: Drought, Dry Soil Sun: Full sun Culture Reliably winter hardy to USDA Zones 8-10. Best growth occurs in a sandy/gritty, dry to medium moisture, well-drained soil in full sun. Container plants may be grown in a gritty, cactus-type potting mix. Sharp soil drainage is important. Poorly-drained soils may lead to root rot. Tolerates dry soils and drought. This agave may be propagated from seed or offsets. Noteworthy Characteristics Agave americana is a rosette-forming perennial succulent that is native to Mexico. It has been introduced and has naturalized in a number of tropical areas around the world. Each plant typically forms a large, evergreen basal rosette of thick, succulent, lanceolate, gray-green leaves. Each rosette typically matures over time to as much as 6' tall by 8-10' wide. Each leaf has a waxy bloom, spiny tip, and sharp marginal spines. This plant is also well-known for its infrequent but spectacular flowering spikes. Plants are monocarpic (bloom only once and then die). Common name of century plant suggests the plant will live 100 years before flowering. In reality, outdoor plants typically bloom between the 10th and 25th years. Indoor plants rarely flower. When an outdoor plant blooms, it sends up a single, stout, erect flowering stalk from the center of the basal rosette of leaves to 15-30' tall or more. The flowering stalk resembles a narrow telephone pole with horizontal branching near the top. Greenish-yellow flowers (each to 3-4" long) bloom in panicles at the branch ends. Suckers/offsets root at the base of each rosette over time, often forming a colony of new plants. Once a plant flowers and dies, the offsets around the base of the plant continue to grow. Problems No serious insect or disease problems. Agave weevil can be troublesome. Slugs and snails may damage foliage. Root rot may occur, particularly in poorly-drained or overly-moist soils. Uses Where winter hardy, this agave serves as an interesting tropical accent or specimen. It is a large and showy plant for the landscape. It needs a large space in which to grow. Plants are often grown in cactus or succulent garden areas. It will grow well in containers as an indoor plant at a much smaller size. .

Genetic Variation and Agronomic Features of Metroxylon Palms in Asia and Pacific
Chapter 4 Genetic Variation and Agronomic Features of Metroxylon Palms in Asia and Pacific Hiroshi Ehara Abstract Fourteen genera among three subfamilies in the Arecaceae family are known to produce starch in the trunk. The genus Metroxylon is the most productive among them and is classified into section Metroxylon including only one species, M. sagu (sago palm: called the true sago palm), distributed in Southeast Asia and Melanesia and section Coelococcus consisting of M. amicarum in Micronesia, M. salomonense and M. vitiense in Melanesia, M. warburgii in Melanesia and Polynesia, and M. paulcoxii in Polynesia. In sago palm, a relationship between the genetic distance and geographical distribution of populations was found as the result of a random amplified polymorphic DNA analysis. A smaller genetic variation of sago palm in the western part than in the eastern part of the Malay Archipelago was also found, which indicated that the more genetically varied populations are distributed in the eastern area and are possibly divided into four broad groups. Metroxylon warburgii has a smaller trunk than sago palm, but the trunk length of M. salomonense, M. vitiense, and M. amicarum is comparable to or longer than that of sago palm. Their leaves are important as building and houseware material, and the hard endosperm of M. amicarum and M. warburgii seeds is utilized as craftwork material. Preemergent young leaves around the growing point of M. vitiense are utilized as a vegetable. Regarding starch yield, palms in Coelococcus are all low in the dry matter and pith starch content as compared with sago palm. For this reason, M.

The entire chloroplast (cp) genome of asparagus was sequenced with Hiseq4000 platform. The complete cp genome maps a circular molecule of 156,699bp built with a quadripartite organization: two inverted repeats (IRs) of 26,531bp, separated by a large single copy (LSC) sequence of 84,999bp and a small single copy (SSC) sequence of 18,638bp. A total of 112 genes comprising of 78 protein-coding genes, 30 tRNAs and 4 rRNAs were successfully annotated, 17 of which included introns. The identity, number and GC content of asparagus cp genes were similar to those of other asparagus species genomes. Analysis revealed 81 simple sequence repeat (SSR) loci, most composed of A or T, contributing to a bias in base composition. A maximum likelihood phylogenomic evolution analysis showed that asparagus was closely related to Polygonatum cyrtonema that belonged to the genus Asparagales.

Effects of Plant Size on Reproductive Output and Offspring Performance In
Journal of Blackwell Science, Ltd Ecology 2002 Effects of plant size on reproductive output and offspring 90, 958–966 performance in the facultative biennial Digitalis purpurea NINA SLETVOLD Department of Biology, Division of Botany and Plant Physiology, University of Oslo, PO Box 1045 Blindern, N-0316 Oslo, Norway Summary 1 Monocarpy in facultative biennials can be favoured by selection when there is a more than proportional increase in fitness with size. The possible contributions of larger reproductive output and higher offspring quality to such an increase were investigated in the facultative biennial plant Digitalis purpurea. Straw mass (rosette leaves and flower- ing stem excluding fruits and seeds) was determined for 100 individuals of varying size and correlated with the number of flowers and seeds per flower to examine whether sex- allocation is size dependent. 2 To determine whether maternal size influences offspring growth, and whether this effect is more pronounced in the presence of competition, seeds from 32 maternal plants were grown alone, and with one, two or four competitors. 3 Total seed number increased proportionally with size. Seed quality, measured as seed size, germination percentage and speed also increased with maternal size. The combined fitness measures of total seed mass (seed number × seed size), number of seedlings (seed number × germination percentage) and total female fitness (seed number × germination percentage × mean offspring dry mass after 14 weeks) all increased disproportionally with size. 4 Sex-allocation was size dependent, with large plants emphasizing the female function. 5 Offspring dry mass after both 8 and 14 weeks of growth was strongly influenced by competition, whereas the effect of maternal size was significant only at the first harvest date.

My advisor Beryl Simpson gave me this opportunity and I will be forever thankful to her for this, as pursuing a career as a plant biologist had been a dream of mine for years. Her unconditional support was instrumental in allowing me to broaden my knowledge of plant systematics and as a foundation for allowing me to develop further my critical thinking and writing abilities. She always guided me in my writing with a great deal of encouragement, compassion, and patience. I will miss our weekly meetings and think back fondly to the many great conversations we had.

Ecophysiology of Crassulacean Acid Metabolism (CAM)

Cell biology, enzymology and the ¯ow of carbon along various pathways and through various cellular compartments have been well documented and dis- cussed. The present attempt at reviewing CAM once again tries to use a different approach, considering a wide range of inputs, receivers and outputs. d Input Input is given by a network of environmental parameters. Six major ones, CO2,H2O, light, temperature, nutrients and salinity, are considered in detail, which allows discussion of the effects of these factors, and combinations thereof, at the individual plant level (`physiological aut-ecology'). d Receivers Receivers of the environmental cues are the plant types genotypes and phenotypes, the latter includ- ing morphotypes and physiotypes. CAM genotypes largely remain `black boxes', and research endeavours of genomics, producing mutants and following molecular phylogeny, are just beginning. There is no special development of CAM morphotypes except for a strong tendency for leaf or stem succulence with large cells with big vacuoles and often, but not always, special water storage tissues. Various CAM physiotypes with differing degrees of CAM expression are well characterized. d Output Output is the shaping of habitats, ecosystems and communities by CAM.
