摘要： 以胡萝卜甜红1号父本和08511#父本为材料,取开花当天的新鲜花粉,分别在24,27,0,,6,9℃恒温条件下处理60 min,通过醋酸洋红染色法和培养基培养法,研究不同温度对胡萝卜花粉活力的影响.结果表明,随着温度的升高花粉活力降低,24℃花粉活力最高,℃以上高温处理会明显抑制胡萝卜花粉活力.08511#父本染色情况好于甜红1号父本,但其花粉萌发率受温度影响较甜红1号父本变化幅度大.

关键词: 胡萝卜, 温度, 花粉活力, 花粉萌发率

Abstract: We chose intraday pollen of male parent of carrot Sweet and Red No. 1 and 08511^# as experimental materials which were treated at 24， 27，3 0， 33， 36，3 9℃ respectively for 60 min to study the effects of different temperature to carrot pollen vigor by testing methods of pollens cultured in vitro and aceto-carmine coloration. Results indicated that carrot pollen vigor reduced along with the rise of temperature. And at 24℃ the pollen showed the highest vigor and remarkably inhibited when the temperature was higher than 33℃. Although coloration of carrot 08511^# was better than that of the male parent of Sweet and Red No. 1，germination rate of which was significantly affected by temperature compared to the later.

Key words: Carrot, Temperature, Pollen vigor, Germination rate
