| 摘 要： | 以对西瓜枯萎病菌抗性不同的西瓜抗病品种(甜妞)、感病品种(天使)和不同的西瓜嫁接砧木(南瓜、葫芦)为试材,研究根系分泌物对西瓜种子萌发及西瓜幼苗根系活力的影响.结果表明:抗病品种根系分泌物对自身种子的萌发、幼苗的根系活力有促进作用,感病品种根系分泌物对自身种子的萌发、幼苗的根系活力有抑制作用,葫芦砧木自根苗根系分泌物对抗、感品种种子的萌发、幼苗的根系活力均有抑制作用,南瓜砧木嫁接苗、自根苗根系分泌物对抗、感病品种的种子萌发、幼苗的根系活力均有显著的促进作用.

| Abstract: | Selected two kinds of watermelon cultivars.Tianniu is resistant to Fusarium oxysporum f.sp niveum(E.F.Smith)Snyder & Hansen and Tianshi is susceptible to it.They were grown as seedlings or on calabash or pumpkin rootstocks as experimental materials.Obtained the extract of root exudates using vermiculite cultivation and investigated effects of root exudates on the germination of watermelon seeds and root activities of watermelon seedlings.The results showed that root exudates of resistant cultivars,grafted s... |
