不同砧木嫁接对樱桃番茄品质及产量的影响

以4个不同番茄砧木品种与夏日阳光樱桃番茄进行嫁接,以夏日阳光自根苗为对照(CK),研究了不同砧木嫁接对樱桃番茄的生长发育、抗病性、抗旱性、品质及产量的影响。试验结果表明,4种砧木嫁接均能显著降低青枯病发病率,其生长势、产量均显著优于自根苗,且品质和口感与自根苗无明显差异,其中,以哥俩好的成活率最高,为95.8%,第一雌花节位最低,采收期最长,青枯病发生率最低,生长势最强,坐果率最高,单果质量最大,糖酸比最大,达7.301,产量最高,达4 858.0 kg/667 m~2,综合表现优异,适宜作为樱桃番茄夏日阳光的嫁接砧木进行推广。

Effects of Different Rootstocks Grafting on Cherry Tomato Yield and Quality

With summer sun self-root seedlings as control, the effects of different rootstocks grafting on cherry tomato growth and development, disease resistance, drought resistance, quality and yield were studied through grafting cultivation with the 4 different tomato rootstocks cultivars and summer sun cherry tomato. The results showed that the incidences of 4 rootstocks grafting significantly reduced, and the growth vigor and fruit yield significantly increased, in addition, the quality and taste of the fruits were no significant difference compared with the self-root seedlings. Taking Gelianghao as rootstocks, grafting cherry tomato plants had the highest survival rate of 95.8%, lower position of the first female flower node, longest picking time, minimum incidence rate of bacterial wilt, strongest growth vigor, highest fruit setting rate, heaviest single fruit weight, biggest sugar-acid ratio of 7.301 and highest yield of 4 858.0 kg/667 m2. It was suitable for popularization and application as the grafting rootstocks of cherry tomato summer sun cultivation in Xinchang area with excellent general performance.
