摘要
以9种西瓜砧木("海砧1号"、"昌砧力士、"先正达白籽、"雪中甲"、"铁木真"、"刚健1号"、"普通小籽"、"南湘白籽"、"新1号"自根苗,对应编号为A1、A2、A3、A4、A5、A6、A7、A8(CK1)、A9(CK2))为试材,调查嫁接苗及实生苗生育状况、病害状况、果实品质及其产量差异,以期筛选适宜的西瓜嫁接砧木。结果表明:嫁接显著增加了叶面积和产量(P<0.05)、主蔓更长、果皮厚度更大、果皮硬度提高并改变了果实形状和风味,但略延迟开花和采收;嫁接能减小西瓜枯萎病和细菌性角斑病发生几率。虽然A8(CK1)嫁接成苗率最高且嫁接苗长势强健,但就单果重、果实品质和抗病性等指标综合考虑,A1优于实生苗和其它砧木,最适于用作海南西瓜嫁接,A6产量高、抗病性较好,也适合海南西瓜嫁接。
9types of melon were used as test materials（‘Haizhen No.1＇,‘Changzhen Lishi＇,‘Xianzhenda Baizi＇,‘Xuezhongjia＇,‘Tiemuzhen＇,‘Gangjian No.1＇,‘Putong Xiaozi＇,and‘New No.1＇seedling,there number were A1,A2,A3,A4,A5,A6,A7,A8（CK1）and A9（CK2））,growth and development about graft or seedling,disease,fruit quality,yield,and so on were investigated,to select suitable watermelon rootstock.The results showed that,graft significantly increased leaf area and yield（P0.05）.At the same time,graft would length main vain,increase melon peel thickness and hardness,and improve fruit shape and flavour.But,graft would delay bloom and harvest gently.Except of‘Tiemuzhen＇（A5）,most watermelon rootstocks would decrease the incidence of blight or Pseudomonas lachrymans.Among 9types of melon rootstocks,‘Haizhen No.1＇（A1）was the most suitable one for high yield and quality and advanced disease resistance.To some degree,‘Gangjian No.1＇（A6）was suitable to graft in Hainan too,with its high yield and high disease resistance.
