摘要:

为研究嫁接对果树硒积累的影响,采用盆栽试验,分别以少花龙葵(二倍体)、少花龙葵经秋水仙素诱导的四倍体后代和龙葵(六倍体)为砧木,以树番茄为接穗进行嫁接,研究不同倍性龙葵砧木对树番茄幼苗的生长和硒积累的影响。结果表明,与未嫁接相比,以不同倍性龙葵为砧木嫁接均能提高树番茄的叶绿素总量、类胡萝卜素含量和硒含量,提高幅度由大到小为六倍体龙葵砧木嫁接>四倍体龙葵砧木嫁接>二倍体龙葵砧木嫁接>未嫁接。以不同倍性龙葵为砧木进行嫁接,提高了树番茄幼苗砧木茎秆、接穗茎秆、接穗叶片和整个接穗的干重和硒积累量,其中以六倍体龙葵砧木的增加效果最为显著。与未嫁接相比,六倍体龙葵砧木嫁接树番茄整个接穗的干重、硒含量和硒积累量分别提高了69.54%、56.43%和165.17%。因此,六倍体龙葵为砧木嫁接可用于促进树番茄的生长,提高树番茄的富硒能力。

Abstract:

The paper aims to study the effects of grafting on the selenium accumulation of fruit tree. The pot experiment was used to study the effects of Solanum nigrum rootstock with different ploidies grafting on the growth and selenium accumulation of Cyphomandra betacea seedlings, the S. photeinocarpum (diploid), colchicine-induced tetraploid S. photeinocarpum post generation and S. nigrum (hexaploid) were used as rootstocks, and C. betacea was used as scion for grafting. The results showed that the different ploidies of S. nigrum rootstocks increased the total chlorophyll, carotenoid and selenium content of C. betacea seedlings compared with the ungrafted, and the order was: hexaploid rootstock> tetraploid rootstock> diploid rootstock> the ungrafted. The different ploidies of S. nigrum rootstocks also increased the dry weight and selenium accumulation amounts of rootstock stem, scion stem, scion leaf and whole scion of C. betacea seedlings, and the best increasing effect was hexaploid rootstock. Compared with the ungrafted, hexaploid rootstock increased the dry weight, selenium content and selenium accumulation amount of whole scion of C. betacea seedlings by 69.54%, 56.43% and 165.17%, respectively. Therefore, hexaploid as rootstock could be used to promote the growth of C. betacea and increase the selenium accumulation ability of C. betacea.

Key words: different ploidies of Solanum nigrum, Cyphomandra betacea, grafting, selenium, photosynthetic physiology, accumulation
