The seed of Cornus officinalis exhibit a dormant physiological postmaturition in autumn harvest, althrough the embryo tissue has developed, it can not germination. This process is retarded by the inhibitor of fresh seed coat and its impermeability and low temperature in winter but it can be promoted by ample oxygen and suitable temperature condition. This experiment has showed that the seed can obtain high germination and break effectively dormant through the stratification of sub-high temperture (21—15℃) for...

The seed of Cornus officinalis exhibit a dormant physiological postmaturition in autumn harvest, althrough the embryo tissue has developed, it can not germination. This process is retarded by the inhibitor of fresh seed coat and its impermeability and low temperature in winter but it can be promoted by ample oxygen and suitable temperature condition. This experiment has showed that the seed can obtain high germination and break effectively dormant through the stratification of sub-high temperture (21—15℃) for 3 months and sub-low temperature (3—15℃) for 2 months in the sand mediun

山茱萸种子在秋熟时,胚形态已发育完全,但不能萌发,表现出一个休眠生理后熟过程。这个过程受到新种皮的抑制物和它的透性不良及冬季低温的阻碍而在有氧和适温条件下得到促进。试验揭示种子在砂基介质中经过3个月的亚高温(21~16℃)与2个月亚低温(3~15℃)层积对休眠破除的有效性,并促进高萌发。

The study shows that the seed of Sassafras tzumu has double dormancy. High concentrated germination inhibitor is the main cause and the impermeability of the seed coat to gases is the other. The dormancy of 90% seed can be broken in chilly (0-5℃) and warm (15-25℃) treatments of stratification. The seed coat retards 60% of the seed germinating after the seed dormancy breaking.

檫树(Sassafrs tzumn Hemsl)种子具有休眠特性,对其休眠生理进行研究表明,该种子属于双重休眠,种子中存在高浓度的发芽抑制物,是其休眠的主要原因。经过冷(0~5℃)或暖层积处理,可导致90%以上的种胚解除休眠,但种子萌发率仍只有60%左右,改善种皮的透气性和消除种皮中的发芽抑制物,是提高檫树种子育苗成功率的关键。

Dormancy is one of the characteristics of Acer truncation seeds. During the dormant period, pericarp and seed coat played an important and manifold role. Before the state of dormancy was over, the undamaged perfect seeds had to be kept under a condition of low temperature (2-5℃), and a stratification for 40~50 days. Under the condition of 25℃, the seeds after removing mulch could germinate without pre-treatment. Seed mulch has inhibitiry effect on oxygen absorption of seed embryo and limits the swelling of embryo...

Dormancy is one of the characteristics of Acer truncation seeds. During the dormant period, pericarp and seed coat played an important and manifold role. Before the state of dormancy was over, the undamaged perfect seeds had to be kept under a condition of low temperature (2-5℃), and a stratification for 40~50 days. Under the condition of 25℃, the seeds after removing mulch could germinate without pre-treatment. Seed mulch has inhibitiry effect on oxygen absorption of seed embryo and limits the swelling of embryo physically and mechanically, and hinders the spread of inhitor to seed germination. During the process of stratification treatment, with the continuous increase of nutritive substance in embryo, the resistance of seeds to inhibitors increased uninterruptedly. Eventually the seeds overcame the inhibition form outer tissue and germinated.

本文对元宝槭种子休眠生理进行了研究。发现未受损的完整种子,在休眠结束之前,需经低温2~5℃层积40~50天处理才可萌发;而剥去果皮、种皮的种子在恒温25℃,每天光照8h条件下,1.5天就萌发,6天萌发率达99%。影响种子休眠的原因主要是元宝槭种子的果皮、种皮对种胚的吸氧量起着阻滞作用,对种胚的膨胀有物理机械性限制作用。其次是抑制物——单宁的向外弥散。经过层积的种子由于酶活性增强,促进了胚内营养物质的转化,因而提高了种子对抑制作用的抵抗能力,使休眠期缩短,萌发期提前。
