木本植物种子综合特征与催芽促进类型相关性的研究

INTEGRATED CHARACTERISTICS OF WOODEN PLANT SEEDS AND THE RELATIVITY OF ADVANCED GERMINATION METHODS

木本植物种子的形态、解剖特征、大小、科属与催芽促进类型之间存在着五种相关性 ,即无胚乳的胚根裸露型种子———用低温或低温层积 ( 0～ 5℃ )处理 ;胚未分化或极细小或深休眠的种子———用低温 ( 0～ 1 0℃ )与高中温相结合处理 ;硬实种子及种皮障碍型种子———用热沸水浸种、化学药剂、机械破碎、干湿交替、细菌侵入、隔年埋藏等处理方法 ;小粒型种子———直播、变温或激素处理 ;直播即可发芽的种子———常温下 ( 1 0～ 2 5℃ )时 ,满足其必要的水分、空气等条件即可萌发。

According to configuration, anatomy, size, and family or genus, there are five methods to advance germination of the wooden plant seeds, namely non-endosperm and radicle-exposed seeds——deal with low temperature or low temperature stratum(0～5℃);Ovule-differentiated or terribly minute or resting seeds——deal with low temperatur(0～10℃)combined with high or middle temperature;Hard and capsule-obstacled seeds——deal with boiling water, chemical medicine, physical crach, bacteria, or being embedded in the second year; Small seeds——direct seeding or deal with hormone;Seeds which will germinate when direct seeding——at normal temperature, fulfil the necessary condition such as water, atmosphere and so on . Many experiments have proved the dependability of these methods.
