摘要：研究砧木、接穗与嫁接愈合、嫁接苗成活及苗木生长的关系,为提高油茶（Camellia oleifera Abel）嫁接育苗提供技术指导。以油茶优良无性系长林4^#、18^#、23^#、40^#为试验材料,采用完全随机试验设计,将砧木设为根段砧木、胚芽段砧木,接穗设为芽1接穗、芽2接穗、芽3接穗、芽4接穗,就不同砧木和接穗组合对嫁接愈合过程及愈合过程中嫁接苗的各项生理及形态指标的影响情况进行研究。结果表明：不同品系、不同砧木和接穗可改变嫁接苗的愈合速率,但均不改变愈伤组织的形成过程,在其愈合过程中,胚芽段砧木的愈合速度较根段砧木快,且胚芽段砧木嫁接成活率、嫁接苗后期长势均高于根段砧木;芽2接穗的嫁接苗愈合更快、且嫁接苗成活率及后期长势均为最高,其次是芽1接穗、芽3接穗、芽4接穗。综合各项指标来看,砧木和穗条会影响嫁接苗愈合进程以及愈合过程中的各项生理指标,胚芽段砧木优于根段砧木,接穗最优的是芽2。
The aim of this study is to find out the ideal stock and scion for the development,survival rate and the growth of Camellia oleifera nurse seed grafting and provide guidance for the improvement of grafting seedling for production,taking Chang lin 4~#,40~#,18~#,23~# as materials,a two factors completely randomized experiment on root stock,shoot stock and shoot1 scion,Shoot 2 scion,Shoot 3 scion and Shoot 4 scion was carried out to study the relationship between stock,scion and development of grafting,the survival rate and the growth of the grafted seedlings. The result shows that different Camellia oleifera varieties,different stocks and scions changed the rate of callosity but could not change the progress of the fornation of callus.During the whole progress of callosity,the callosity of shoot stock was faster than that of the root stock and also shoot stock got the higher survival rate and better growth,among them,Shoot 2 scion got the faster callosity and higher survival rate and better growth than other shoot scions.In all,stock and scion affected the callosity of grafting and the physiological indicators and it turned out that shoot stock was better than root stock and Shoot 2 was the best scion.
