Flower number

Ornamentals are treated with GA for a variety of purposes including more profuse flowering, increasing flower number, and in some circumstances flower size. It is a common practice in the southeastern United States to gib camelHas prior to flowering, ie, a small amount of the potassium salt of GA at 100 ppm is dropped into the floral bud at a very early stage of development to produce large showy flowers.

Brassinolide solution was sprayed until flowers and fruits were completely wet. Treatments were done on the day of anthesis and also 2 months after anthesis when "June drop" had ceased. During June drop non-treated plants showed ca. 98% abortion (Table HI). Flower numbers and initial fruit set were computed on the day of treatment. 

It s found [9] that in selection for seed productivity it s possible to receive positive results, using phenotypic selection on following traits coloration of flowers, number of generative shoots, size of flowering heads and inflorescences. Seed production depends heavily upon content of starch in the root crown in the period of flowering (correlation coefficient r = 0.63), content of sugar in nectar (r = 0.78) and presence of pollinators (r = 0.95). 

In A. celastrifolia the flower number per head is reduced to (l-)2-3 flowers, which contrasts with most other acacias Acacia s.l.), in which the heads are many-flowered. Guinet et al. (1980) highlight that Acacia gilbertii is highly unusual...

When mitosis is blocked by colchicine, the treated cells may be left with an extra set of chromosomes. Plants with extra sets of chromosomes are typically larger and more vigorous than normal plants. Flowers developed in this way may grow with double the normal number of petals, and fruits may produce much larger amounts of sugar. 

Sdfabac, var- trifolLilum, known in India as kadda mulla, differs from the ocher varieties in bav ing solitary flowers, the calyx of wbieb is divided mio a large number of segmeuts, and tbe leaves I P. and fi.O.ft. (J916I, 36. 

Terrestrial biomass is divided into a number of subreservoirs with different turnover times. Forests contain approximately 90% of all carbon in living matter on land but their NPP is only 60% of the total. About half of the primary production in forests yields twigs, leaves, shrubs, and herbs that only make up 10% of the biomass. Carbon in wood has a turnover time of the order of 50 years, whereas turnover times of carbon in leaves, flowers, fruits, and rootlets are less than a few years. When plant material becomes detached from the living, plant carbon is moved from the phytomass reservoir to litter. "Litter" can either refer to a layer of dead plant material on the soil or all plant materials not attached to a living plant. A litter layer can be a... 

A number of investigators have successfully selected cell lines which have higher tolerance to salinity than the line from which they were selected (see Spiegel-Roy Ben Hayyim, 1985 Rains et al., 1986 for a list of plant species). An evaluation of these selected lines demonstrates a number of differences in ionic status and cell wall regulation, but there are relatively few cases where the salinity tolerance of whole plants that have been regenerated from this material have been determined (see Yeo Flowers, Chapter 12).

The flavonoids universally occur in vascular plants, in which they are often responsible for the colors of flowers and fruits, although they are also present (often less apparently) in roots, stems, and leaves [10]. The number of possible sources from which these compoimds can be isolated is very large and much useful information on this can be obtained in reviews [10-12]. 

Tea flowers are globular, about 3 to 5 cm in diameter, white, and delicately fragrant. They are borne in the axils of scale leaves (small leaves that do not develop further) and may occur singly or in small clusters. There are five to seven petals and an equal number of sepals. The flowers are mostly self-sterile and are produced in cycles corresponding to leaf growth, and require 9 to 12 months to form mature, round seed pods 1 to 1.5 cm in diameter. The tea plant is not generally allowed to flower during production cycles, with only a small number of the plants allowed to go to seed production to maintain seed stock.
