棉花花粉量的多少和生活力的强弱,对开花受精、成铃和棉铃的发育有直接影响,并与皮棉的产量和品质有关.,棉花花粉发育除与其内在的发育条件有关外,还受着外界因素的影响.例如,在花粉发育敏感时期,常受温度、水分、营养等条件的支配,其中温度往往起主导作用.据阿巴也娃(1940,1941)报导,棉花在开花结铃时期,过高的温度对花粉发育有不良影响,并使脱落增加.迈耶尔也曾报导,在密西西比州的斯通维尔地方,当温度增加到38℃以上时,不孕花药数量也随之增加,高温和不孕花药的出现相隔的时间为15～16天.刘志翼报导陆地棉108φ品种,在新疆日平均气温30℃以上时脱落逐渐增加,32℃以上的剧烈增加.王缨报导,在
Cotton pollen amount and the strength of the vitality, on the flowering and fertilization, boll and boll development has a direct impact, and lint yield and quality related to cotton pollen development in addition to its inherent development conditions, but also by For example, in pollen development sensitive period, often subject to temperature, moisture, nutrition and other conditions, in which the temperature tends to play a leading role.According to Ababa (1940, 1941) reported that cotton bolls Meyer has also reported that in the area of Stoneville, Mississippi, when the temperature rises above 38 ° C, the number of infertile anthers also increases as a result Increase, high temperature and infertility anthers emergence of the time interval of 15 to 16. Liu Zhiyi reported upland cotton 108φ varieties, when the daily average temperature in Xinjiang off more than 30 ℃, drastic increase above 32 ℃. Wang Ying reported that at
