摘要
用０．２ｍｍｏｌ·Ｌ－１草酸，３０％蔗糖，５０ｍｇ／ＬＡＢＡ，１０ｍｇ／Ｌ硼酸培养液对１２份耐菌核病性不同的油菜品种（系）的花粉粒离体萌发进行了观察。结果表明，与对照（不加草酸的培养液）的萌发率相比，耐病材料的萌发率受抑不明显，感病材料的萌发率大幅度下降。
Pollens of 12 rapeseed (B. napus) cultivars/lines with different tolerance toSclerotinia sclerotiorum were evaluated for their in vitro germination using culture solutioncontained 0.2 mmol. L-1oxalic acid, 30% sucrose, 50 mg/L ABA, 10 mg/L boric acid. Compared with percentages of pollen germination in culture solution without oxalic acid(CK),percentages of germination for the tolerant materials were not obviously decreased,however,those for susceptiple ones decreased significantly.
