嫁接防治苦瓜枯萎病研究

Studies on engraft preventing fusarium wilt of Balsam pear

进行了嫁接防治苦瓜枯萎病的研究,结果表明闽研1号苦瓜和山东威龙2号南瓜嫁接亲和性最好,成活率高达94.7%。2个南瓜品种作砧木均可有效地防治苦瓜枯萎病的发生,校正防效均达到100%,防治效果极显著地好于2个芋瓠品种。嫁接后砧木为威龙2号南瓜和黑子南瓜的粗蛋白分别增加了26.63%、21.35%;砧木为威龙2号南瓜的维生素C增加了20.56%,砧木为黑子南瓜的维生素C却降低了40.56%;以2个南瓜品种作砧木嫁接后在水分方面与闽研1号实生苗差异不明显。

In this paper,it was studied for engraft preventing fusarium wilt of balsam pear. The results showed that the affinity was the best between the pumpkin ‘Shandong weilong No. 2＇ and the balsam pear ‘ minyan No. 1＇. The survive rate was up to 94.7 %. Two pumpkin stocks could both prevent the fusarium wilt of Balsam pear effectively,the corrected controlling effects were both up to 100 %. The effects were better than the two calabash gourds as stocks. After engrafting,the coarse protein increased 26.63 % and 21.35 % ,respectively,as stocks were‘ Shandong weilong No. 2＇ and ‘yunnan black seed＇. The vitamin C increased 20, 56 % as stock was ‘Shandong weilong No. 2＇ ,while reduced 40.56 % as stock was‘ Yunnan black seed＇, The difference was not obvious in the water between the seedling engrafted by the two pumpkin stocks and the ‘Minyan No. 1＇ seedling.
