Rootstock ± vertical, 5-12 mm in diam., not tuberculate, with thickened roots along rootstock. Stem 16-50 cm tall, erect, not rooting at nodes, with 0.2-1.3 mm retrorse to patent nonglandular trichomes and rarely 0.7-0.8 mm patent glandular trichomes.

根茎多少垂直，直径5-12毫米，不具瘤，根沿着根茎加粗。16-50厘米高的茎，直立，并非根在节上，具0.2-1.3毫米对开展非腺状毛状体和很少开展腺毛0.7-0.8毫米。

Gene sequence was highly homologic with a gene encoding aβ- subunit of ATP synthetase and an EST originating from a cDNA in relation to water deficit stress, which both were closely associated with the protein functioning in stress resistance and ion transportation. The results suggested that No. 1 gene sequence was involved in stress resistance of apple rootstock. No. 2 gene sequence had high homology with a gene encoding a serine/ threonine kinase protein, indicating perhaps it was a new gene encoding the serine/ threonine kinase protein in apple rootstock. The gene sequences of A1 and A2 were highly homologic with a gene encoding aβsubunit of ATP synthetase.

对得到的差异片断进行回收、测序，通过BLAST和其它植物比对，发现Ⅰ号序列与一条编码ATP合酶β亚基基因和一条水分亏缺胁迫cDNA克隆基因EST的同源性非常高，该序列编码涉及到了抗性表达、离子转运基因，可能参与了植物抗性表达，说明获得的基因序列应是与苹果砧木抗性相关的基因；Ⅱ序列与一条serine/threonine kinase蛋白激酶的蛋白序列同源性比较高，核酸比对较低，可能是具有丝氨酸/苏氨酸蛋白激酶功能的新基因。A1、A2序列与一条编码ATP合酶β亚基基因的同源性较高。

Rootstock：砧木

简介 砧木(rootstock) 嫁接繁殖时承受接穗的植株. 砧木可以是整株果树,也可以是树体的根段或枝段,起固着、支撑接穗并与接穗愈合后形成植株生长、结果. 砧木是果树嫁接苗的基础. 嫁接用的砧木,要选择生育健壮,根系发达,适应当地环境条件,

Rootstock：根砧木

对其周围方圆5公里的葡萄园进行虫害检测. 遭受根瘤蚜虫侵害的葡萄树产量会逐渐降低,直至树木最终死亡,但是受感染的葡萄树死亡后不可以运到其它地区. 制止根瘤蚜虫害扩散的有效方法是,与北美能抵御葡萄根瘤蚜虫的根砧木(rootstock)嫁接.

Rootstock：根茎

rootstalk 根茎 | rootstock 根茎 | rootworm 食虫

Rootstock：砧木,根茎,初生主根

root zone 根带,根区 | rootstock 砧木,根茎,初生主根 | round-arched tunnel 拱圆形大棚

dwarfing rootstock：矮化砧

矮化砧(dwarfing rootstock) 能控制接穗生长、使嫁接树树体小于标准树体的一类砧木. 利用矮化砧木栽培的苹果树冠为乔砧树的1/2-2/3利用矮化砧适于密植,栽植后一般2-4年开始结果,6-8年即进入丰产,矮化砧木已在世界苹果生产中广为应用,
