近年来小果型西瓜的栽培面积增长迅速,为筛选出适宜小果型西瓜嫁接的南瓜砧木,以17个南瓜砧木和2个商业南瓜砧木(丰乐金甲、京欣砧4号)作为嫁接砧木,以小果型西瓜品种京美2K和武农8号作为接穗,研究不同南瓜砧木嫁接对西瓜嫁接苗成活率、定植成活率、植株田间长势、开花坐果节位、果实品质和产量的影响。结果表明,参试砧木均与小果型西瓜具有较高的亲和性;嫁接小果型西瓜的田间长势和产量优于自根栽培;除砧木S6和S26外,其他砧木嫁接不会显著改变西瓜果形指数;在内在品质指标中,春季以S12、S19、S5、S16、S13、S7和S17表现良好,秋季以S16、S19和S7表现最优。综合春秋两季的试验结果,S16、S19和S7这3个南瓜砧木优于2个商业砧木,适宜作为小果型西瓜的嫁接砧木。
