从试管苗到成苗要经过一个从培养基到基质的移栽过程,其生长环境将发生较大的变化。这就给花卉爱好者提出了一个问题——采取怎样的措施才能使幼苗安全过渡呢?笔者是从以下几个方面着手的。一、培养健壮试管苗供移植的试管苗应是完整而健壮的植株,其标准是:株高2厘米左右,叶柄短粗,叶片大而浓绿;新根白色,短而多(根3～4条,每条长10～15毫米)。这类苗移植后能迅速恢复生机。因此,幼苗培养中应注意两点:一是在诱导分化期,培养基中应使用两种激素(生长素),这比单用一种效果更好。二是丛生
From test tube seedlings to mature through a medium from the substrate to the transplanting process, the growth environment will have a greater change. This raises a question for the flower lover - what kind of measures can be taken to make the seedlings safely transition? The author starts from the following aspects. First, the training of robust plantlets for transplantation Plantlets should be complete and robust plant, the standard is: about 2 cm in height, petiole short and thick, leaves large and dark green; new root white, short and more (root 3 ~ 4, each 10 to 15 mm long). These seedlings can quickly restore vitality after transplantation. Therefore, seedling culture should pay attention to two points: First, the induction of differentiation, the medium should be used in two hormones (auxin), which is better than a single effect. Second, clusters
