摘要
为筛选出适宜秋季中果型西瓜嫁接的南瓜砧木,以西瓜品种美都作为接穗,以9个自育南瓜砧木(H1~H9)和2个商业南瓜砧木(丰乐金甲和京欣砧4号,H10和H11)作为嫁接砧木,以2个商业南瓜砧木(H10和H11)和自根苗(H12)为对照,研究秋季不同南瓜砧木嫁接西瓜后对嫁接亲和性、西瓜幼苗生长、田间适应性、果实产量和品质等性状的影响。结果表明,各砧木与西瓜嫁接亲和性均较好,嫁接苗的种苗质量、田间长势和产量均优于自根苗,其中砧木H1、H2、H7、H8、H9的增产效果和H2、H6、H7、H8、H9嫁接的西瓜果实内在品质均优于2个商业南瓜砧木。对21项重要指标进行主成分和隶属函数分析,综合评价筛选出了H9、H7和H83份南瓜砧木,在嫁接西瓜苗期壮苗指数、产量、可溶性固形物含量、感官评价得分等方面均优于商业南瓜砧木丰乐金甲和京欣砧4号,相比于自根苗增产率达20.45%~27.98%,适宜作为湖北省等相同生态区域的中果型西瓜秋季设施栽培的嫁接砧木。
To screen suitable pumpkin rootstocks for medium-size grafted watermelon in autumn,nine hybrid pumpkin rootstocks and two commercial rootstocks(Fengle Jinjia and Jingxin Zhen No.4)were evaluated using Meidu watermelon as the scion.Two commercial pumpkin rootstocks(H10 and H11)and self-rooted seedlings(H12)were used as control.This study investigated the effects of different pumpkin rootstocks on grafting compatibility,seedling growth,field adaptability,yield,and fruit quality of watermelon.The results indicated that all tested rootstocks exhibited high compatibility with watermelon.Grafted seedlings demonstrated superior quality,growth vigor and yield compared to self-rooted seedlings.H1,H2,H7,H8,and H9 showed better yield;H2,H6,H7,H8,and H9 exhibited superior intrinsic fruit quality compared to the commercial rootstocks.Through principal component and membership function analysis of 21 key indicators,rootstocks H9,H7,and H8 were comprehensively evaluated as superior to Fengle Jinjia and Jingxin Zhen No.4 in terms of seedling strength index,yield,soluble solids content and sensory evaluation score,increasing yield by 20.45%-27.98%compared to self-rooted plants.These pumpkin rootstocks are recommended as suitable options for medium-size grafted watermelon cultivation in autumn,particularly in ecological zones with conditions similar to those of Hubei province.
