Reproductive ecology of Agalinis acuta was investigated by examining potential for self-fertilization before and at anthesis, reproductive output from outcrossed vs. selfed matings, and effects of browsing, plant size, and conspecific plant density on seed and fruit production. These features of a plant species can provide indirect information pertinent to conservation such as patterns and main...

in order to identify the best maturity time for excision of fertilized ovules in interspecific hybridization, intercrosses were made between two diploid (gossypium herbaceum and g. arboreum, 2n=26) and two tetraploid species (g. barbadense and g. hirsutum, 2n=52). flower morphology, growth rate of ovules and ovaries, as well as fiber growth pattern in various time scales post anthesis were reco...

In 2022, a field experiment was conducted to investigate the efficacy of fungicide programs on Fusarium head blight (FHB) and deoxynivalenol (DON) levels. Fungicide treatments were evaluated in plots hard red winter wheat cultivar ‘KanMark’ inoculated with graminearum Parsons, KS. Treatments consisted single application Prosaro, Caramba, Miravis Ace, Prosaro Pro, or Sphaerex at early anthesis (...

In order to explore the effect of relationship between combination sowing date and nitrogen application rate on status rice plants uptake transfer after anthesis, three dates were set—23 May (S1), 2 June (S2), 12 (S3)—and four fertilizer treatments—no (N0), 180 (N1), 270 (N2), 360 (N3) kg N/hm2—were applied in a field experiment. The dynamic characteristics post-anthesis under different treatme...

Translocation of nitrogen was measured in wheat (Triticum aestivium L. cv SUN 9E) plants grown without an exogenous supply of nitrogen from the time that the flagleaf began to emerge, and a model of nitrogen translocation was constructed to describe translocation on one day during the linear period of grain growth. Nitrogen for grain development was derived entirely by the redistribution of nit...

The relationships of fruit age, abscisic acid (ABA) concentration, ethylene evolution, and abscission rates were studied in an effort to determine why cotton (Gossypium hirsutum L., cv. Deltapine 16) fruits rarely abscise more than 15 days after anthesis. Because abscission of cotton fruits is increased by conditions that limit photosynthesis, greenhouse-grown plants with fruits of various ages...

We aimed to optimize field border length in the Huang-Huai-Hai Plain of China (HPC) reduce soil inorganic nitrogen residues and increase absorption utilization by wheat plants using a traditional irrigation system. In two-year experiment (2017–2019) conducted HPC, four lengths were tested: 20 m (L20), 30 (L30), 40 (L40), 50 (L50). Supplementary was implemented during jointing anthesis stages, c...

in this study the effects of source limitation on grain yield of twelve barley cultivars (‘aras’,‘jonub’,‘reihan’,‘zarjou’,‘sararoud’,‘sahra’,‘fajr30’,‘karoun’,‘gorgan’,‘makouei ’and ‘nosrat(’ under post anthesis water deficiency were studied. source limitation treatments were included that control, removing of awn, leaves below flag leaf, flag leaf and spike photosynthesis. all source limitati...

Fungicides used to control Fusarium head blight (FHB) are commonly applied at the wheat growth stage considered be most susceptible, i.e., anthesis. We compared efficacy of fungicide groups that were following two strategies: (i) pre-defined stages, from first half heading end flowering (experiment 1, in 2013 2015), or (ii) based on timing infection by F. graminearum, specifically 10, 7, 4, 1 d...
