several plant growth regulators are used to improve the quality of cut flower in bulb plants, but their effectiveness depends on genotype and plant growth conditions such as nutrition status. a pot experiment was conducted under farm condition to study benzyl adenine (ba) and potassium nitrate interaction on floret diameter, stem diameter, flower height, flower number per bulb, fresh and dry we...

BACKGROUND AND AIMS The perianthless Piperales, i.e. Saururaceae and Piperaceae, have simple reduced flowers strikingly different from the other families of the order (e.g. Aristolochiaceae). Recent molecular phylogenies proved Verhuellia to be the first branch in Piperaceae, making it a promising subject to study the detailed structure and development of the flowers. Based on recently collecte...

Moringa oleifera is an important source of antioxidants, tools in nutritional biochemistry that could be beneficial for human health; the leaves and flowers are used by the population with great nutritional importance. This work investigates the antioxidant activity of M. oleifera ethanolic (E1) and saline (E2) extracts from flowers (a), inflorescence rachis (b), seeds (c), leaf tissue (d), lea...

The investigation aimed to study the effect of foliar application chemicals on plant canopy, vegetative growth and flowering, as well overall appearance Ixora chinensis plants grown in pot. Application salicylic acid, benzyl adenine silicon at different concentrations significantly influenced growth, pigments compared untreated (control). Plants treated with 10 mg/l 20 acid showed significant i...

Quantitative analyses of sexual expression show extensive interspecific variation in the strength of andromonoecy (proportions of hermaphroditic and staminate flowers) among Solanum species in the monophyletic section Lasiocarpa. The roles of phenotypic plasticity and inter- and intra-inflorescence architecture in the diversification of andromonoecy within this small clade were analyzed. Four s...

Two non-mutually exclusive hypotheses regarding the benefits of andromonoecy (producing perfect and female-sterile flowers on the same plant) are tested using Solanum carolinense. Results indicate that (1) staminate flowers are cheaper to produce than perfect flowers, even after correcting for their relative position in the inflorescence; (2) the resources saved by producing staminate flowers a...

• As we know, the inflorescences that will produce any year’s grape crop start differentiating inside the buds in the previous year. There are 2 main stages of development: formation of primary branches starts in Year 1, before the vine goes dormant; secondary and tertiary branching, as well as individual flower differentiation, continues around budbreak of Year 2. Thus, the cropping potential ...

the zinnia (zinnia elegans j.) flower has many applications in landscape design, whereas lack of adequate conditions and nutritions in some cases can reduce the quality and number of flowers. therefore, control of growth conditions is very important related to nutrition and application of growth regulators to improve the quality and quantity of flowers. flower's morphology and longevity are two...
