不同砧木嫁接对番茄生长、品质及田间综合抗病性的影响

Effects of Grafting of Different Rootstocks on Growth,Quality and Comprehensive Disease Resistance in the Field of Tomato

为了研究不同砧木嫁接亲和性,通过对7种不同番茄砧木品种与接穗品种"桃星"进行嫁接栽培,研究其对接穗生长势、果实性状、品质、产量及田间抗病性的影响。结果表明:共生亲和性是选择优良砧木的关键,砧美103、力王神根、TZ-1这3个砧木品种综合表现较好,产量分别比接穗自根苗增产91.5%、64.0%、60.9%,可溶性固形物含量分别比接穗自根苗增加1.08%、2.15%、6.45%,田间发病率分别比接穗自根苗下降10.0、6.7、13.4个百分点,可作为"桃星"嫁接砧木在宁波地区嫁接番茄生产中进行应用。

In order to study grafting affinity,seven different tomato rootstock cultivars and scion cultivar'Taoxing'were grafted to study the effects of different rootstocks on scion growth,fruit traits,quality,yield and disease resistance.The results showed that the symbiotic affinity was the key to select excellent rootstocks.Compared with the scion self-rooted seedlings,‘Zhenmei 103'‘Liwangshengen'and‘TZ-1'had better comprehensive performance,and the yield increased by 91.5%,64.0%and 60.9%,the content of soluble solid increased by 1.08%,2.15%and 6.45%,respectively,and the incidence rate of field disease decreased by 10.0,6.7 and 13.4 percentage points,respectively.These rootstocks could be used as‘Taoxing'grafting rootstocks in the production of grafted tomato in Ningbo area.
