木本植物细胞小,染色体不易分散,观察比较困难,茶树也不例外。我们研究出“去壁低渗压片法”,使染色体的分散不受细胞限制,获得较清晰的标本。这一方法也适用于新梢尖。制片方法 1.取材:根于8—9时切取根尖4—5毫米;嫩梢于5时半—7时半摘取顶端,剥去外 Woody plant cells, chromosomal dispersion is not easy to observe, tea is no exception. We developed a “wall-to-wall hypotonic tablet method”, so that the chromosomes are not restricted by the cells to obtain clearer specimens. This method also applies to the tip of the tip. Production methods 1. Drawn: rooted at 8-9 when cutting apical 4-5 mm; tender shoot at 5:30 half past 7 am and pick the top, stripped outside
