聚合多抗砧木对番茄产量、品质及抗病性的影响

Effects of Polymeric Material with Multi-resistance Root-stocks on Tomato Yield,Quality and Disease Resistance

以砧木品种西大砧木1号(聚合多抗材料)、申砧、野生砧木,接穗品种磊石901为试材,研究聚合多抗砧木对番茄生长势、产量、品质及抗病性的影响。结果表明:嫁接可以显著提高番茄植株质量、产量和果实品质,还可以增强植株抗病性;果实性状指标的隶属函数平均值排序为西大砧木1号嫁接苗(0.79)>申砧嫁接苗(0.70)>野生砧木嫁接苗(0.51)>磊石901自根苗(0.38);根系发达程度为西大砧木1号嫁接苗>野生砧木嫁接苗>申砧嫁接苗>磊石901自根苗;嫁接苗植株质量和生长指标的隶属函数平均值排序为西大砧木1号嫁接苗(0.70)>野生砧木嫁接苗(0.50)>申砧嫁接苗(0.27)>磊石901自根苗(0.16);果实品质指标隶属函数平均值大小排序为西大砧木1号嫁接苗(0.51)>申砧嫁接苗(0.50)>野生砧木嫁接苗(0.37)>磊石901自根苗(0.36);此外,西大砧木1号嫁接产量较高,田间对南方根结线虫、枯萎病、青枯病有较高的抗性,细菌性髓部坏死病发病率为仅5%,含有枯萎病抗性基因I-2、根结线虫抗性基因MI-1,属于聚合多抗材料。

Taking the root-stock varieties‘Xidazhenmu No.1＇,‘Shenzhen＇,wild rootstock and scion variety‘Leishi 901＇as test materials,this paper studied the effects of grafting with different root-stock varieties on tomato growth vigor,yield,quality and disease resistance.The results showed that grafting could significantly improve tomato plant quality,yield,fruit quality and strengthen the plant disease resistance.The fruit characteristic index order was‘Xidazhenmu No.1＇（0.79）‘Shenzhen＇（0.70） wild rootstock（0.51） ‘Leishi 901＇own-rooted tree（0.38）.The order of root development level was‘Xidazhenmu No.1＇ wild rootstock ‘Shenzhen＇ ‘Leishi 901＇own-rooted tree.The quality of grafting seedlings and growth index of the plant was‘Xidazhenmu No.1＇（0.70） wild rootstock（0.50）‘Shenzhen＇（0.27）‘Leishi 901＇ownrooted tree（0.16）.The order of average fruit quality index value was‘Xidazhenmu No.1＇（0.51）‘Shenzhen＇（0.50） wild rootstock（0.37）‘Leishi 901＇own-rooted tree（0.36）.Besides,the‘Xidazhenmu No.1＇ grafting seedling had higher yield,good resistance to root knot nematode,blight and wilt in fields.The morbidity of tomato bacterial pith necrosis was 5%.‘Xidazhenmu No.1＇had blight resistance gene I-2 and root knot nematode resistance gene MI-1.It was belong to polymeric material with multi-resistance.
