摘要
通过大量收集野生茄科植物作为栽培番茄的嫁接砧木 ,进行嫁接试验并观察嫁接成活率。栽植各砧木苗、番茄实生苗及嫁接成活率较高的嫁接苗 ,观察比较它们在自然条件下青枯病的发病率 (如果自然条件下青枯病发病率低的地块 ,可考虑人工接种病原 )、植株生长情况、产量和品质等 ,筛选出 2种嫁接成活率高 ,抗青枯病能力强 ,并能保持或提高接穗果产量和品质的番茄嫁接砧木。为深入进行番茄抗青枯病种苗选育研究和生产实践奠定了基础。
By collecting a large number of wild Solanum species as tomato's grafting stocks, grafting and observing the surviving rate, planting the stock seedlings, tomato seedlings and high surviving rate grafting seedlings, the growth of these seedling, the product and the quality of their fruits, and their infection rate of Pseudomonas solancearum (the seedlings were infected the pathogen artificially if not infected in the natural condition)were observed and compared. According to the results, two wild species of Solanum as tomato's grafting stock were selected out. These two species had high grafting surviving rate and strong anti decease ability, and their grafting seedlings can yield more product and their fruit have better quality. The results of this experiment are significant for the further research and applyed in this field.
