Abstract: [Objective] The Fusarium Wilt of melon is becoming more and more serious,which has seriously affected the quality and yield of melon.In order to prevent the occurrence of Fusarium Wilt and improve the quality and yield of melon,the effects of grafting of different types of Rootstocks on the quality,chlorophyll and organic acid of muskmelon were studied.[Method] 13 root stocks were selected to graft with Xizhoumi No.25.The main characters for grafting compatibihty,chlorophyll,quality and organic acids were checked and analyzed.[Result]The results indicated that the survival rate of pumpkin rootstock and gourd rootstock was higher than that of muskmelon.The highest grafting survival rate was highest and the minimum rate was Qinkangshuigua-Xizhoumi No.25 (97.95;) and the lowest one was SK54-2-Xizhoumi No.25 (70.59;).Variance analysis showed that after the grafting of different densities,the diameter of SK54-2-Xizhoumi NO.25 was decreased and the edge and central soluble solids of Qinkangshuigua-Xizhoumi No.25,Kehongzhen No.2-Xizhoumi No.25 and SK54-2-Xizhoumi No.25 decreased,the flesh of 7363-Xizhoumi No.25 became thinner,the flesh of Qinkangshuigua-Xizhoumi No.25,Kehongzhen No.2-Xizhoumi No.24 and SK54-2-Xizhoumi No.25 became thicker.No obvious differences in transverse diameter,cavity size and fruit shape indes were found between the different combinations.Compared with CK,there were no differences in color and flesh,but reticulate pattern became thicker to some degree,and flesh taste become bad.There were no significant differences in chlorophyll a,b,chlorophyll a/b,organic acids and VC content compared with CK.Grafting could effectively reduce the incidence of Fusarium Wilt.[Conclusion] On the whole,the combination of pumpkin rootstock was better than that of gourd rootstock combination and melon rootstock combination.Pumpkin rootstocks 7473,Qinkangshuigua and Cuiyu performed better results,so did in gourd rootstock combination of Qinkangshuigua-Xizhoumi No.25.

摘要： [目的]生产中甜瓜枯萎病日益严重,影响甜瓜的品质及产量,为了防止枯萎病的发生,提高甜瓜的品质及产量,研究不同类型砧木嫁接对甜瓜品质、叶绿素、有机酸等的影响.[方法]用南瓜砧、葫芦砧、甜瓜砧3种不同类型的砧木13份,以西州密25号为接穗采取顶插接的方法进行嫁接,以未嫁接的西州密25号为对照,对叶片中叶绿素含量、果实品质、有机酸含量、VC含量进行测定.[结果]南瓜砧和葫芦砧的嫁接成活率高于甜瓜砧,嫁接成活率最高的是亲抗水瓜-西州密25号组合(97.95;),成活率最低的是SK54-2-西州密25号组合(70.59;);方差分析表明,西州密25号经不同砧木嫁接后,SK54-2-西州密25号组合的纵径降低,亲抗水瓜-西州密25号组合、科鸿砧二号-西州密25号组合、SK54-2-西州密25号组合的边糖、心糖降低,7363-西州密25号组合的肉变薄,亲抗水瓜-西州密25号组合、科鸿砧二号-西州密25号组合、SK54-2-西州密25号组合的皮增厚,各组合间的果实横径、种腔大小、果形指数与对照间不存在极显著差异.与对照相比,外观和肉色无变化,网纹有不同程度的变粗,肉质口感略变劣.各砧木-接穗组合处理间叶绿素a、叶绿素b、叶绿素a/b、有机酸含量、VC含量与对照间均不存在极显著差异性,嫁接可有效降低枯萎病的发生.[结论]南瓜砧木组合优子葫芦砧木组合和甜瓜砧木组合,南瓜砧木组合中7473-西州密25号组合、绿神嫁接王-西州密25号组合表现较好,葫芦砧木组合中亲抗水瓜-西州密25号组合,甜瓜砧木组合中翠玉-西州密25号组合表现较好.
