The establishment of regeneration system of potato plantlets in vitro from potato stem - apex meristem 马铃薯茎尖分生组织试管苗再生体系的建立
Advances on genetic transformation of cotton shoot apical meristem via gene - gun bombardment 以棉花茎尖分生组织为受体进行基因枪轰击转化的研究
Inhibiting the symptom of sweet potato witches ' broom and improving plantlets formation in apical culture by electro - treatment 电流处理抑制甘薯丛枝病症状及提高茎尖培养成苗率
Studies on tip meristem culture rapid propagation and induction of in vitro stolon of manyflower betony stachys floridana schuttl . ex benth 银条茎尖培养快繁及离体根状茎的诱导
The level of 5 - metylcytosine in dna of plant decreased 14 . 52 % compared to control after treatment with ga of 300mg / l 300mg l赤霉素处理后，植株茎尖的dna甲基化水平比对照下降了14 . 52 。
And development foregrounds is that propagation coefficient of the tip meristem culture is high and the range of increasing in yield is clear 茎尖组织培养前景广阔，具有繁殖系数高、增产幅度大等特点。
The article studies potato virus - free seedling multiplication technology , we studied the breaking away virus position and the method of inducing stem tip producing growing thick tooth , and we have used simplified medium and low expensive culture vessel 摘要对马铃薯块茎的脱毒部位、诱导茎尖产生丛生芽的技术进行了研究；并采用简化的培养基、低价耐用培养容器培育脱毒苗。
Using " shanghai no . 4 " and " dongcun jiaopei " as donor materials , variants with improved heat tolerance were obtained through treating haploid stem apexes with pingyangmycin and then culturing survived stem apexes with stress of higher temperature 摘要用平阳霉素对青花菜“上海4号”和“东村交配”的单倍体茎尖进行诱变处理，以高温作为选择压力，获得一批耐热性明显比原始品种提高的单倍体变异体。
