Rice anthesis
WebbIn both CMS lines and testers of rice, maximum blooming stage of panicles was recorded 9.00 am to 1.00 pm while 8.00-11.00 days took for fully completion of anthesis. In CMS lines of rice, receptivity of stigma ranged from 36 to 42 hrs (two to three days). There was no difference in stigma receptivity stages among the three CMS lines of rice. Webb1 nov. 2024 · Thus, improving the simulation of heat stress on spikelet fertility and potential grain number may be more important than the methodology used for carbon assimilation alone, especially if episodic high heat events during anthesis and/or grain-fill periods continue to be problematic in rice growing regions [53].

Webb2 feb. 2024 · Spikelet sterility in the rice crop is becoming a burning issue in the context of global warming since it may occur as soon as air temperature reaches 33°C at time of anthesis [ 1] even if it is for less than an hour of exposure [ 2 ], a situation which can already be encountered in many rice growing areas [ 3 ].
WebbThe rice plant is most sensitive to low temperature at meiosis or panicle initiation. The outstanding Vietnam entry tolerant of 17 degrees Celsius air temperature at panicle initiation was Bong Sen (Acc. 10861) with a score of 1; Tep Trang and Ba Ren were relatively tolerant at panicle initiation and at the seedling stage.
