不同砧木对黄瓜产量、果霜及抗病性的影响

Effect of Different Parental Stocks on Output,Bloom and Disease Resistance on Cucumber

以河北农业大学蔬菜育种系选育的系列砧木品系为试材,以黑籽南瓜为对照,对嫁接后黄瓜的产量、表皮果霜以及抗病性等进行了研究。结果表明:A2、B1的早期产量均显著高于黑籽南瓜,其中A2的总产量显著高于黑籽南瓜,B1则与黑籽南瓜相近;A1的早期产量和总产量与对照差异不显著;B2、B3则明显不如黑籽南瓜。不同砧木对果实表皮果霜的影响差异显著,B1在整个结瓜期均不出现霜果,A1只有少数果实有果霜。参试砧木的抗病能力差异不显著,抗枯萎能力均达到高抗水平。综合评价以A2、B1最好,A1也较优良。

Taking series parental stock varieties as experimental materials provided by Agricultural University of Hebei,using black seed pumpkin for control,the yield,bloom and disease resistance of grafted cucumber were studied.The results showed that the early production of cucumbers engrafted on A2and B1was greater than it on Cucurbita ficifolia.The output of cucumbers on A2was obviously greater than those on Cucurbitaf icifolia.In this aspect,B1was also close to Cucurbita ficifolia and B2and B3were inferior to Cucurbita ficifolia.The impact of different parental stocks on bloom varies greatly.Bloom doesn＇t appear on cucumbers engrafted on B1throughout their whole fruiting period and it only appears on only a few of cucumbers engrafted on A1.The resistance of experimental parental stocks against diseases differs slightly and it against blight reached a high level.In conclusion,A2and B1were the best parental stocks and A1 was better than some others.
