分别以枳和阿尔及利亚夏橙作为砧木,以迟熟蕉柑芽作为接穗进行茎尖嫁接,结果枳砧嫁接成活率为9.1%,阿尔及利亚夏橙砧嫁接成活率为54.5%,将两种砧木嫁接苗再嫁接在枳砧上,其3年生幼树均生长正常,表明阿尔及利亚夏橙是茎尖嫁接迟熟蕉柑的优良砧木。应用指示植物鉴定方法和PCR检测技术鉴定7株茎尖嫁接苗的柑橘碎叶病、衰退病、裂皮病和黄龙病,结果1、3、4、5、6号迟熟蕉柑单株不带碎叶病、衰退病、裂皮病和黄龙病,可作为繁殖无病苗木的备选材料;2、7号迟熟蕉柑单株不带碎叶病、裂皮病和黄龙病,但带有衰退病,推测衰退病毒源可能来自取芽的田间植株。
Respectively trifoliate orange and Algeria summer orange as the rootstock, with late-ripening banana citrus shoots as the scion for shoot tip grafting, the survival rate of grafted Aurantii were 9.1%, the grafted survival rate of Alnaria summer orange was 54.5%, the two kinds of rootstocks grafted seedlings Then grafted on the orange antelope, the 3-year-old saplings are normal growth, indicating that summer orange is the root tip of late grafted Jiaogan good rootstock. The indications of plant identification and PCR detection were used to identify citrus leaf fragment disease, recession disease, split-skin disease and yellow dragon disease in seven shoot-tip grafted plants. Broken leaf disease, recession disease, split skin disease and Huanglong disease, can be used as breeding material for disease-free seedlings; late No. 2,7 late banana banana leaves without fragmentation, split disease and Huanglong disease, but With the recession, it is speculated that the source of the recession virus may come from the budding field plants.
