核桃不定根发生调控的组织和免疫化学的研究.pdf

定位观察生根过程中IAA变化，结果如下： 整个核桃子叶中均有IAA的分布，但主要集中分布在未成熟的网状维管组织中，维 管发育完善后，主要集中在维管束周围的分生组织中。并且，近胚端IAA信号最强，由 近胚端到远胚端IAA信号逐渐减弱。 在子叶生根过程中IAA的运动路线是：未成熟的维管组织专成熟维管组织周围的环 形分生组织专根原基专中柱鞘专根尖生长点。 关键词：核桃，子叶，不定根，解剖构造，免疫定位 Ⅱ Abstract isdifficulttoinduceto adventitious thereare some Jugians produce root，therefore difficultfor elitecultivars．After of adventitious asexualitymultiplication successfullyinducing root ofinvitro onthe mechanismofadventitiousroot walnut，researches centeringregulation Was main aboutthe carriedout．The results and histology,hormonalregulation arethebelow． immunohistochemistry 1、Theinvitrostems walnut wasinduced of‘Xinzaofeng’，avariety bytwo-stagerooting to the oftheadventitiousrootsoftheirinvitro Was protocolroot,and development seedling examined．Theresultsshowedthat： anatomically root inthein dormant Wasfounded vitrotenderstemsofwalnut． (1)No primordial oftheadventitiousroots inthe the (2)Theprimordial originated cambiumover the then root wereinduced and they part againstpithyrays，thus pdmordial occurredinmono-sites． lateralrootsoftheadventitiousroots inthe cells． (3)The
