broccoli (brassica oleracea l. cv premium crop) florets were packaged using two types of polymeric films (polyethylene, ld & polypropylene cast) and then stored at 1?c for 18 days to study the effect of passive and active map (1.5%o2+7.5%co2) on preservation of quality and nutritional value as compared to non-wrapped control florets. during storage, weight loss, rate of ethylene production, qua...

Extending the duration of the late reproductive phase in wheat has been proposed as a possible avenue to improve spike fertility. There is a positive correlation between the number of fertile florets and the duration of the stem elongation phase when this phase is varied by extended photoperiod. Photoperiod treatments imposed during the vegetative period also influence the duration of stem elon...

The maize (Zea mays) spikelet consists of two florets, each of which contains three developmentally synchronized anthers. Morphologically, the anthers in the upper and lower florets proceed through apparently similar developmental programs. To test for global differences in gene expression and to identify genes that are coordinately regulated during maize anther development, RNA samples isolate...

Hydrogen peroxide (H 2 O ) is a reactive oxygen species (ROS) which participates in the signal transduction responses of plants toward biotic and abiotic stresses. Therefore, objective this study was to link exposure low doses H improvement phytochemical composition broccoli florets, particular content glucosinolates (GLS), hydroxy-cinnamates (HCA) without affecting quality parameters vegetable...

in this study, effect of exogenous putrescine on maintaining postharvest quality and antioxidant compounds of two broccoli cultivars, ‘general’ and ‘liberty’ during cool storage were investigated. broccoli branchlets were treated with 0.5, 1 and 1.5 mm putrescine. distilled water was used as control. treated florets were put into polyethylene bag and transferred to storage with 0°c and 90% rh. ...

Three models of plant phyllotaxis are presented. Phyllotaxis is shown to be governed by subtle properties of number which insure that the florets are arranged so as to have the most space and therefore have the greatest access to sunlight. The mathematical tools discussed are Farey series, Wythoff’s game, continued fractions, and a Fibonacci number system called Zeckendorf notation.

Lavender flower essential oil had been used for a variety of therapeutic and cosmetic purposes. Previous studies mainly focused on composition extraction methods, ignoring the factors that affected production oils, such as floret number. This study aims to get deep insight into mechanism number differences. Hormone analysis showed there was positive correlation between abscisic acid (ABA) conte...

Sex determination in maize is controlled by a developmental cascade leading to the formation of unisexual florets derived from an initially bisexual floral meristem. Abortion of pistil primordia in staminate florets is controlled by a tasselseed-mediated cell death process. We positionally cloned and characterized the function of the sex determination gene tasselseed1 (ts1). The TS1 protein enc...

A new species of Asteraceae from Taiwan, Senecio kuanshanensis C.-I Peng & S.W. Chung, a distinct member of sect. Crociseris (Reichenb.) Hall. & Wohlf. ser. Nemorenses Gagnidze, is described and illustrated. Senecio kuanshanensis is apparently rare, presently known only from mountain ridges of Kuanshan, at (2,500-)3,000-3,300 m elevation in the southern part of the Central Mountain Range of Tai...

trypesis caricae, a species in the same genus as the wasp studied by Murray; the numerals 8 and 9 show the elongated eighth and ninth abdominal segments, followed posteriorly by the long sheaths that hold the ovipositor, which is used to drill through the outside wall of the fig into the ovaries of the pistillate florets inside. Right: According to Joseph 9, these are three forms taken by males...
