目前,生产上检验林木种子生活力,常用化学药品洋红、胭脂红等进行染色,也有用四唑染色的。这些药品价格高,难保存,染色速度慢,在生产中使用不方便。针对这一问题,我们进行了红墨水染色试验。经多次试验证明:用红墨水染色,能快速测定林木种子生活力,比用胭脂红染色快7倍,而且准确。这种染料易于购买,价格低廉,存放方便,使用方法简单,容易掌握。一、染色的原理:种胚的活细胞壁,具有选择渗透能力。某些化学染料,如苯胺类 At present, the production of forest seed vitality test, common chemical magenta, carmine and other staining, but also useful tetrazolium staining. These drugs are expensive, difficult to preserve, slow to dye and inconvenient to use in production. In response to this problem, we conducted a red ink staining test. After several tests proved that: with red ink staining, can quickly determine the viability of forest seed, than carmine staining 7 times faster, and accurate. This dye is easy to buy, inexpensive, easy to store, easy to use and easy to handle. First, the principle of staining: Embryonic live cell wall, with the choice of penetration. Some chemical dyes, such as aniline
