【摘要】 采用花粉离体培养技术研究营养元素与植物生长调节剂对油菜花粉萌发的影响。结果表明：在适宜的浓度范围内，硼、尿素、锌、钼、６－苄基腺嘌呤（ＢＡ）和萘乙酸（ＮＡＡ）对花粉萌发均有促进作用。０．０１％的硼砂和０．１％的尿素、０．１ｍｇ／Ｌ的硫酸锌、１０～４０ｍｇ／Ｌ的钼酸钠、１ｍｇ／Ｌ的ＢＡ和１０ｍｇ／Ｌ的ＮＡＡ促进花粉萌发及花粉管生长的作用最显著。更多还原

【Abstract】 Influences of nutrition elements and plant growth regulators on the germination and growth of rape pollen were studied in vitro. The results showed that boron, urea, Zn, Mo, Benzyladenine (BA) and Naphthaleneacetic acid (NAA) stimulated the germination and growth of rape pollen in proper concentration. The stimulated actions were significant with the different concentration, which list as follows: 0.01% boron, 0.1% urea, 0.1mg/L ZnSO4,1040mg/L Na2MoO4, 1mg/L BA and 10.0mg/L NAA.更多还原
