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. -
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. -

Poisonings and deaths from garden plants Poisoning are rare as most poisonous plants taste unpleasant Poisoning from plants may occur from ingesting, and are seldom swallowed (see toxicity). However, it is inhalation or direct contact. best to know which plants are potentially toxic. Symptoms from ingestion include gastroenteritis, It is important to remember that small children are diarrhoea, vomiting, nervous symptoms and in serious often at risk from coloured berries, petals and leaves cases, respiratory and cardiac distress.

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. -
Nerine Bowdenii Final Trials Report 2012–2017
Nerine bowdenii Final Trials Report 2012–2017 Trials Office, RHS Garden Wisley, Woking, Surrey, GU23 6QB RHS Registered Charity No: 222879 / SC038262 RHS Trial of Nerine bowdenii Introduction to the Trial The genus Nerine contains 25 species, most well known of which is the Guernsey lily (N. sarniensis) a greenhouse plant. All the species occur in southern Africa but only a very few are truly hardy in the UK. Since its introduction to cultivation in 1898 N. bowdenii has become widely grown in gardens and a diverse range of forms has been developed, either by selection or hybridisation. The scale of this diversity was revealed by the Hardy Nerine Study Day in October 2007. From that point onwards the idea of a trial grew, mainly through the efforts of the then National Plant Collection holder for hardy nerines, Mrs Margaret Owen. The trial agreed was an RHS off-site trial, run jointly by the RHS and the Nerine and Amaryllid Society (NAAS). Two sites were chosen to test the hardiness of the entries: one in the north (The Patch, Acton Pigott, Shropshire – site of the then National Plant Collection) and one in the south (Bramdean House, Bramdean, Hampshire – site of an extensive collection of nerines owned by Mrs Victoria Wakefield). Although the intention was to have entries in common to both sites to allow proper comparison, the difficult process of putting the trial together meant that not all the entries were grown at both sites. A particular challenge for the trial was the fact that many of the entries were not named or not properly named as cultivars. -

Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes
Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes Shichao Chen1., Dong-Kap Kim2., Mark W. Chase3, Joo-Hwan Kim4* 1 College of Life Science and Technology, Tongji University, Shanghai, China, 2 Division of Forest Resource Conservation, Korea National Arboretum, Pocheon, Gyeonggi- do, Korea, 3 Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, United Kingdom, 4 Department of Life Science, Gachon University, Seongnam, Gyeonggi-do, Korea Abstract Phylogenetic analysis aims to produce a bifurcating tree, which disregards conflicting signals and displays only those that are present in a large proportion of the data. However, any character (or tree) conflict in a dataset allows the exploration of support for various evolutionary hypotheses. Although data-display network approaches exist, biologists cannot easily and routinely use them to compute rooted phylogenetic networks on real datasets containing hundreds of taxa. Here, we constructed an original neighbour-net for a large dataset of Asparagales to highlight the aspects of the resulting network that will be important for interpreting phylogeny. The analyses were largely conducted with new data collected for the same loci as in previous studies, but from different species accessions and greater sampling in many cases than in published analyses. The network tree summarised the majority data pattern in the characters of plastid sequences before tree building, which largely confirmed the currently recognised phylogenetic relationships. Most conflicting signals are at the base of each group along the Asparagales backbone, which helps us to establish the expectancy and advance our understanding of some difficult taxa relationships and their phylogeny. -
Lesson 3 RECOGNISING PLANT FAMILIES and IDENTIFYING PLANTS Aim Distinguish Between Different Plant Families and to Become Profi
Lesson 3 RECOGNISING PLANT FAMILIES AND IDENTIFYING PLANTS Aim Distinguish between different plant families and to become proficient at identifying plants. The best way to build your ability to identify plants is by working with or handling a variety of different plants on a daily basis. The first ten plant names you learn are always much more difficult than the next ninety. Similarly, the first 100 names are always much more difficult than the next 900. If you plan to be a skilled gardener, landscape designer, or horticulturist: you need to learn to identify hundreds of different plants. As you have seen earlier; there is a system in identifying plant names. BECOME FAMILIAR WITH PLANT FAMILIES If you can get to know the way the system works, and the broad categories, the whole thing starts to make a great deal more sense. Each new name you confront is able to be associated with things and remembered more easily. FOR EXAMPLE: “When I see a plant with a daisy flower, I immediately know that it is in the Asteraceae family. Even if the genus is new to me, I will be more likely to remember it because I’m not only thinking: This is the genus of this new plant , but I am also thinking: This new genus is in the Asteraceae family. In essence, my brain is registering two pieces of information instead of one and that doubles the likelihood of me remembering the plant. BECOME FAMILIAR WITH LATIN Plant naming is based on the ancient Roman language of Latin.
