木本植物种子综合特征与催芽促进类型相关性的研究

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(0~10℃)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(10~25℃)时,满足其必要的水分、空气等条件即可萌发。很多试验证明了方法的可靠性。

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

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.
