Poor spikelet fertility under low temperature (LT) stress during anthesis limits the possibility of high yield potential in indica-japonica hybrid rice, leading to reduced stability of grain yield. However, the cause for it is still unclear. In this study, three indica-japonica hybrid rice cultivars, Yongyou9, Yongyou17 (both cold sensitive), and Yongyou538, and one japonica inbred rice cultiva...

Bulbs of tulip (Tulipa gesneriana L. `Gander'), in which the formation of ̄oral organs had been completed, were chilled at 28C for 3±30 weeks and then forced hydroponically at 208C under a 12 h photoperiod with the light at 100 mmol mÿ2 sÿ1. The fresh weight and the perianth length of the cut ̄ower highly correlated with the dry weights of shoots and ̄oral organs at anthesis, respectively. The d...

Glume-unclosing after anthesis is a widespread phenomenon in hybrid rice and also a maternal hereditary trait. The character of Glume-unclosing in rice male sterile lines also seriously influences germination rate and the commercial quality of hybrid rice seeds. We validated that the type of glume-unclosing after anthesis in the elite rice thermo-sensitive genic male sterile (TGMS) line RGD-7S ...

BACKGROUND AND AIMS The morphological structure of anthetic carpels of Brasenia (Cabombaceae), a member of the phylogenetically basal ANITA grade, has not been studied before. The carpel has a long stigmatic crest on the ventral side and could give the impression of a conduplicate structure. This is in contrast to the carpel structure in other genera of the ANITA grade. Therefore, a study of ca...

Soybean (Glycine max [L.] Merr.) ovary growth was measured from anthesis to 6 days after anthesis (DAA) to establish a timetable of biochemical events that might be useful in identifying processes that initiate abscission. Two procedures were developed to provide samples with either high or low percent pod set for ;IX93-100,' a semideterminate line having long racemes. Characteristics measured ...

Efficacy of fungicide applications during and after anthesis against Fusarium head blight and deoxynivalenol in soft red winter wheat. Plant Dis. 98:1387-1397. Seven field experiments were conducted in Ohio and Illinois between 2011 and 2013 to evaluate postanthesis applications of prothioconazol...

using crop simulation models is an efficient complement to experimental research. crop models can also be helpful with respect to decision-making in sustainable farming system. this study was done to estimate genetic coefficients and evaluate performanced dssat in prediction of development, growth and yield in wheat. data from various field experiments for four wheat cultivars koohdasht, shirou...

Changes in dry weights, reduced N, nitrate, and nitrate reductase activity of various plant parts of the above ground vegetation (stover) and ears of field grown maize were measured at intervals between anthesis and grain maturity. Nonstructural carbohydrate contents were also measured in some instances. Changes in dry weight and reduced N content were used to approximate net in situ photosynth...

Ginger (Zingiber spectabile) is cultivated worldwide as a floriculture and landscaping species. Studies on the biology floral morphology of this species are important for its improvement; however, they scarce. We investigated reproductive gingers grown in germplasm bank. Floral development was monitored during pre-anthesis anthesis periods. morphometry, pollen viability, stigmatic receptivity, ...
