| 摘 要： | 为进一步探查茉莉酸类植物激素对花粉萌发的影响,研究二氢茉莉酸(DHJA)和茉莉酸甲酯(MeJA)对丝瓜和油菜花粉萌发的效应。将自然开颖散粉的丝瓜花粉和油菜花粉弹落在不含和含不同浓度的DHJA或Me-JA的半固体花粉发芽培养基上,分别在适宜温度下保温保湿培养一段时间后镜检观察花粉萌发情况。结果表明:0.000 5~0.002 5 mol/L的DHJA或MeJA明显抑制丝瓜花粉的萌发,0.000 25~0.001 mol/L的DHJA或MeJA明显抑制油菜花粉的萌发。

| Abstract: | To understand the possible influence of jasmonates on pollen germination,the effects of dihydrojasmonic acid(DHJA) and methyl jasmonate(MeJA) on sponge gourd and rape pollen germination were investigated.Sponge gourd and rape pollens from spikelets of natural anthesis were harvested and immediately spread onto pollen germination mediums with or without DHJA or MeJA of different concentrations.After the pollens were cultured at fit temperature under moist conditions for a period of time,the percentage of germinated pollen was surveyed with microscope.The results showed that DHJA and MeJA at the concentrations from 0.000 5 to 0.002 5 mol/L inhibited the germination of sponge gourd pollens and the concentrations from 0.000 25 to 0.001 mol/L inhibited the germination of rape pollens. |
