1.水浸催芽水浸目的是使种子充分吸水膨胀,种皮软化,加速酶的活动,促进贮藏物质水解,给种子发芽裂嘴创造条件。这种方法适用于大多数树种的种子。技术关键是应掌握浸种的水温和浸种时间。一般水温分为3个梯度:(1)高温浸种。水温80℃,甚至100℃。适用于种皮特别坚硬而致密、透水性很差的种子,如刺槐、合欢等。(2)中温浸种。水温45~70℃,一般60℃左右。适用于种皮较厚的种子,如马尾松、侧柏、紫穗槐等。(3)常温浸种。水温20~30℃。适
1. Flooding The purpose of flooding is to make the seeds full of water to swell, the seed coat softens, accelerating enzyme activity, promote the storage of material hydrolysis, to create the conditions for seed germination. This method is suitable for most species of seeds. The key technical point is that we should master the soaking temperature and soaking time. General water temperature is divided into three gradient: (1) high temperature soaking. Water temperature 80 ℃, or even 100 ℃. For the seed coat is particularly hard and dense, poor water permeability of seeds, such as acacia, acacia and so on. (2) soaking in medium temperature. Water temperature 45 ~ 70 ℃, generally about 60 ℃. Suitable for thicker seeds, such as Pinus massoniana, Arborvitae, Amorpha fruticosa and so on. (3) soaking at room temperature. Water temperature 20 ~ 30 ℃. suitable
