摘要: 分别进行了4个番茄砧木品种ZJ-1,ZJ-3,ZJ-7,ZJ-9对番茄青枯病的抗性,与番茄接穗品种浙杂203亲和性及其嫁接苗对番茄青枯病抗性的测定。结果表明,zJ-1和zJ-9是防治番茄青枯病的最佳抗病砧木,且它们与接穗品种浙杂203的嫁接亲和力强,其嫁接成活率都超过99%;分别接种3个不同小种的番茄青枯病菌,以ZJ-1和7,1-9为砧木的浙杂203嫁接苗的平均成活率分别为97.4%和97.8%,与浙杂203非嫁接苗的平均成活率(为75.0%)差异极显著。经田问对嫁接苗的长势、产量和品质测定,以ZJ-1,ZJ-9为砧木的浙杂203嫁接苗的青枯病病株率均小于5.0%,大大低于对照植株浙杂203的发病率21.4%,比不嫁接的浙杂203分别增产92.2%和101.7%。且嫁接苗的生长势强,对果实的品质无影响。

Abstract: Four tomato rootstock varieties( ZJ-1,ZJ-3,ZJ-7 and ZJ-9)were selected as rootstock and Zheza203 was selected as scion to investigate the graft compatibility and the resistance to tomato bacterial wilt.The results showed that ZJ-1 and ZJ-9 were the best rootstock for disease-resistance,which had higher graft compatibility with Zheza203 and whose grafting survival rates were more than 99%.After the inoculation of three Ralstonia solanacearum isolates respectively, the grafting survival rates were 97 .4% and 97 .8% when Zheza203 was grafted with the stocks of ZJ-1 and ZJ-9,while only 75.0% of
Zheza203 could survive without grafting,showing significant difference.After grafted with ZJ-1 and ZJ-9,the disease plant rates of Zheza203 were lower than 5%,significantly lower than 21.4% of the control Zheza203 without grafting.Meanwhile,the yields of the grated combinations(ZJ1-203 and ZJ9—203)were increased by 92.2% and 101.7% respectively,compared with Zheza203 without grafting.In addition, the grafting seedlings of ZJ1—203 and ZJ9—203 had strong growth and had no effect on the fruit quality.
