STUDY on GROWTH, DEVELOPMENT and SOME BIOCHEMICAL ASPECTS of SEVERAL VARIETIES of Nerine
• STUDY ON GROWTH, DEVELOPMENT AND SOME BIOCHEMICAL ASPECTS OF SEVERAL VARIETIES OF Nerine by KUMALA DEWI partia,1 Submitted in,fulfilment of the requirements for the A degree of Master of Science Studies Department of Plant Science University of Tasmania May, 1993 DECLARATION To the best of my knowledge and belief, this thesis contains no material which has been submitted for the award of any other degree or diploma, nor does it contain any paraphrase of previously published material except where due reference is made in the text. Kumala Dewi ii ABSTRACT Nerine fothergillii bulbs were stored at different temperatures for a certain period of time and then planted and grown in an open condition. The effect of the different storage temperatures on carbohydrate -; content and endogenous gibberellins w Ct,5 examined in relation to flowering. Flowering percentage and flower number in each umbel was reduced when the bulbs were stored at 300 C while bulbs which received 50 C treatment possess earlier flowering and longer flower stalksthan bulbs without 5 0 C storage treatment. Carbohydrates in both outer and inner scales of N. fothergillii were examined semi-quantitatively by paper chromatography. Glucose, fructose and sucrose have been identified from paper chromatogramS. Endogenous gibberellins in N. fothergillii have been identified by GC - SIM and full mass spectra from GCMS. These include GA19, GA20 and G Al, their presence suggests the occurence of the early 13 - hydroxylation pathway. The response of N. bowdenii grown under Long Day (LD) and Short Day (SD) conditions w as studied. Ten plants from each treatment were examined at intervalsof 4 weeks. -
Patterns of Plant Diversity and Endemism in Namibia
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Stellenbosch University SUNScholar Repository Bothalia 36,2: 175-189(2006) Patterns of plant diversity and endemism in Namibia P. CRAVEN* and P VORSTER** Keywords: Namibia, phytogeography, plant endemism ABSTRACT Species richness, endemism and areas that are rich in both species and endemic species were assessed and mapped for Namibia. High species diversity corresponds with zones where species overlap. These are particularly obvious where there are altitudinal variations and in high-lying areas. The endemic flora o f Namibia is rich and diverse. An estimated 16% of the total plant species in Namibia are endemic to the country. Endemics are in a wide variety o f families and sixteen genera are endemic. Factors that increase the likelihood o f endemism are mountains, hot deserts, diversity o f substrates and microclimates. The distribution of plants endemic to Namibia was arranged in three different ways. Firstly, based on a grid count with the phytogeographic value of the species being equal, overall endemism was mapped. Secondly, range restricted plant species were mapped individually and those with congruent distribution patterns were combined. Thirdly, localities that are important for very range-restricted species were identified. The resulting maps of endemism and diversity were compared and found to correspond in many localities. When overall endemism is compared with overall diversity, rich localities may consist o f endemic species with wide ranges. The other methods identify important localities with their own distinctive complement of species. INTRODUCTION (1994). It was based on distributional data per magiste rial district following Merxmiiller (1966-1972), as well Species diversity was traditionally measured by count as other literature. -

Sell Cut Flowers from Perennial Summer-Flowering Bulbs
SELL CUT FLOWERS FROM PERENNIAL SUMMER-FLOWERING BULBS Andy Hankins Extension Specialist-Alternative Agriculture, Virginia State University Reviewed by Chris Mullins, Virginia State University 2018 Commercial producers of field-grown flower cut flowers generally have a wide selection of crops to sell in April, May and June. Many species of annual and especially perennial cut flowers bloom during these three months. Many flower crops are sensitive to day length. Crops that bloom during long days such as larkspur, yarrow, peonies and gypsophila cannot be made to bloom after the summer equinox on June 21st. Other crops such as snapdragons may be day length neutral but they are adversely affected by the very warm days and nights of mid-summer. It is much more challenging for Virginia cut flower growers to have a diverse selection of flower crops for marketing from July to September when day length is getting shorter and day temperatures are getting hotter. Quite a few growers offer the same inventory of sunflowers, zinnias, celosia and gladiolas during the middle of the summer because everything else has come and gone. A group of plants that may offer new opportunities for sales of cut flowers during mid-summer are summer-flowering bulbs. Many of these summer-flowering bulbs are tropical plants that have only become available in the United States during the last few years. The first question that growers should ask about any tropical plant recommended for field planting is, " Will this species be winter hardy in Virginia?" Many of the bulb species described in this article are not very winter hardy. -

Newsletter No. 4 Autumn 2005
The Southern African Bulb Group Newsletter No. 4 Autumn 2005 The Southern African Bulb Group was initiated by a group of enthusiasts on April 4th 2004. The objective of the group is to further the understanding of the cultivation of Southern African bulbs, where `bulbs' is used in the broad sense to encompass bulb-, corm- and tuber- possessing Southern African plants, including `dicots' such as Oxalis. In the first instance the group will be run on an informal basis, with an initial subscription of £5 invited from participants. Committee: Robin Attrill (Membership secretary and Newsletter editor), Margaret Corina (Treasurer), Stefan Rau and Terry Smale Editorial This issue of the newsletter contains a report of the meeting of the group held at Rupert Bowlby's Nursery on April 9th 2005, an article on Crinum moorei by David Corina, information on recent literature of interest to growers of Southern African bulbs, and an updated list of suppliers of seed and bulbs/corms of Southern African geophytes. In addition a balance sheet covering the first year of operation of the group is attached. With respect to the supplier list, please let me know if you are aware of other sources which should be included. As I have previously stated the group welcomes articles, and suggestions, for inclusion in future newsletters. Contributions (hand/typewritten and electronic are acceptable!) are urgently required and should be sent to the newsletter editor at 17 Waterhouse Moor, Harlow, Essex, CM18 6BA (Email [email protected] ) Publication of the next issue is scheduled for December 2005. Report on visit to Rupert Bowlby - Saturday 9 th April 2005 by David Corina About 20 members attended the event, and the Group would like to thank Rupert for his hospitality at the event and for opening his collection to the public gaze. -
Field Grown Cut Flowers
Nursery FACTSHEET September 2015 Field Grown Cut Flowers INTRODUCTION The culture of field grown flowers is an area of floriculture that is generating a lot of interest and is enjoying a steady growth rate. It provides a way to enter the floriculture industry without the $100 to $150 per square metre capital costs that are involved in some greenhouse crops. Recently, the largest area of growth has been in the specialty cut flowers as opposed to the more traditional field grown crops like statice, dahlias and gypsophila. As gardening increases in popularity, home consumers are becoming familiar with the many new and different flower species. In turn, consumers are starting to look for and demand these flowers in floral design work. Site Selection Whether you plan to lease or own the land, there are basic, yet important, site considerations (see Table 1). It is easier if you start with a suitable site rather than try to modify it later. Table 1. Considerations when selecting a production site Soil: It should be fertile and well drained. Soil tests are a basic management tool. Even if you are familiar with the soil in the area, it must be tested to determine pH, organic matter and nutrient levels. A pH of 6.0–6.5 is suitable for most cuts. Know the requirements of your crop before you make any major changes. Water: Good quality water must be available in sufficient quantities. Have the water source tested to determine essentials like pH and EC (salinity). Terrain: Flat land is easier to work. Watch out for low lying pockets that might be prone to early and late frosts, or flooding during the wet months. -
JUDD W.S. Et. Al. (1999) Plant Systematics
CHAPTER8 Phylogenetic Relationships of Angiosperms he angiosperms (or flowering plants) are the dominant group of land Tplants. The monophyly of this group is strongly supported, as dis- cussed in the previous chapter, and these plants are possibly sister (among extant seed plants) to the gnetopsids (Chase et al. 1993; Crane 1985; Donoghue and Doyle 1989; Doyle 1996; Doyle et al. 1994). The angio- sperms have a long fossil record, going back to the upper Jurassic and increasing in abundance as one moves through the Cretaceous (Beck 1973; Sun et al. 1998). The group probably originated during the Jurassic, more than 140 million years ago. Cladistic analyses based on morphology, rRNA, rbcL, and atpB sequences do not support the traditional division of angiosperms into monocots (plants with a single cotyledon, radicle aborting early in growth with the root system adventitious, stems with scattered vascular bundles and usually lacking secondary growth, leaves with parallel venation, flow- ers 3-merous, and pollen grains usually monosulcate) and dicots (plants with two cotyledons, radicle not aborting and giving rise to mature root system, stems with vascular bundles in a ring and often showing sec- ondary growth, leaves with a network of veins forming a pinnate to palmate pattern, flowers 4- or 5-merous, and pollen grains predominantly tricolpate or modifications thereof) (Chase et al. 1993; Doyle 1996; Doyle et al. 1994; Donoghue and Doyle 1989). In all published cladistic analyses the “dicots” form a paraphyletic complex, and features such as two cotyle- dons, a persistent radicle, stems with vascular bundles in a ring, secondary growth, and leaves with net venation are plesiomorphic within angio- sperms; that is, these features evolved earlier in the phylogenetic history of tracheophytes. -
David Domoneys Complete Guide to Seeds and Bulbs
Do David money’s COMPLETE GUIDE To bs Seeds and Bul Let’s begin at the beginning Knowing where plants come from and how they grow is important if you want to grow strong, healthy plants. Understanding seeds and bulbs will help you become a better gardener. What’s in this guide? First we will look at seeds and the different techniques for sowing them indoors and directly outside. We will also explore how to care for seedlings, plus the right ways to collect and store seeds from your plants. In the second part, we will talk about the different types of bulbs, how to plant them and the best ways to create year-round displays. Seeds Growing your own plants from seed is always exciting. Seeing them develop into new plants is very rewarding, and it’s a cost-effective way to add to your garden. What are seeds? A seed is the unit of reproduction for most plants. It contains all the genetic information needed to create an entirely new plant, plus a nutrient store to help it get started. So many types of plants can be grown from seed, from herbs and vegetables to annual and perennial flowering species. Most seeds need warmth and moisture to germinate, but some need bright light or a cooler environment to get started. Others require soaking before sowing. There will be full instructions on the seed packet, but here I will show you a few general tips to help you get started. Find more guides at davidomoney.com Sowing outdoors Some seeds can be sown directly into the ground where you want them to grow.
