染色体镜检是植柏物倍性育种、遗传学及分类学研究的一项实验技术。西瓜和甜瓜染色体小,较难观察;采用根尖染色体检查技术,则易于观察到,且不受季节限制。 将供检查的西瓜种子浸泡,置25℃条件下催芽。为使水分易于浸透种子,可在种壳上用小刀切一小口。甜瓜种子不需要浸种,可直接用培养 Chromosome microscopy is a ploidy breeding, genetics and taxonomy of an experimental technology. Watermelon and melon chromosomes are small, more difficult to observe; using apical chromosome examination, it is easy to observe, and not subject to seasonal restrictions. The watermelon seeds for inspection will be soaked at 25 ℃ under the conditions of germination. To make the water easy to penetrate the seeds, the shell can be used a small knife to cut a small mouth. Melon seeds do not need seed soaking, can be used directly in culture
