Due to the abnormal anthocyanin accumulation , the purple spotted pigmentation was observed in the immature seed coats . in the wide type plants , the normal immature seeds were pale green 由于花青苷的异常积累，突变体未成熟种子的种皮呈现紫红色的斑点；野生型植株幼嫩的种皮没有花青苷的异常积累，呈淡绿色。
Seed macromorphology and seed - coat micromorphology of 11 species of kadsura ( schisandraceae ) represented by 36 samples were observed under light microscope ( lm ) and scanning electron microscope ( sem ) 在光学显微镜和扫描电镜下对南五味子属11种植物36个样品的种子宏观形态及种皮微形态特征进行了研究。
The main causes for dormancy of water dropwort aren ' t seed coat obstacle and physiological dormancy of embryo , but some inhibitors which may be the key factor cousing deep dormancy of water dropwort 但种皮障碍、胚的生理休眠不是水芹种子休眠的主要原因；发芽抑制物质可能是引起水芹种子深休眠的关键性因素。
Terminology in common use is collected and introduced , such as seed like fruit , structures of seed , surface and section of seed , appendages , specialized structures on the seed coat , texture , and so on 解释了常用种子形态学术语，包括种子状果实、种子各组成部分、种子表面及切面、附属物、种皮特化结构、质地等。
The methods for breaking dormancy in hard seeds are generally classified into physical , chemical and biological treatments , which hasten germination by improving seed coat permeability , gas exchange , and water entrance and relieve mechanical constraints 硬实的处理方法大体可分物理、化学和生物3类，这些方法通过改善种皮的通透性，促进气体交换和水分进入，消除机械限制而促进萌发。
We studied water permeability of seed coat , development of embroy , absence or presence of germination inhibitors and some other aspects in order to confirm the dormany causes of mulberry seeds from north of heilongjiang province 摘要从种皮透性、胚的发育、是否存在萌发抑制物等方面，对产于黑龙江省的实生桑种子休眠原因进行了研究，初步认为，胚的生理性休眠是实生桑种子休眠的主要原因。
Secondly , the observation of the arabidopsis thaliana seeds which were irradiated by the ion beam through the sem found that with the increase of the ion beam dose , the ion beam mechanical erosion degree of the seeds was deep . and there are many holes and gaps in the surface of the seeds in dose 通过扫描电镜对离子注入后的拟南芥种子的观察发现，经离子注入过的种子种皮有明显的孔洞和裂痕，并且注入离子对干种子表皮的作用程度随剂量的增大而加深。
This review focused on the developments of plant synthetic seed technology in the past 20 years , and summarized different items on artificial seeds : the concept , significance , status , application prospect , induction and synchronization of somatic embryogenesis , the way of encapsulating , artificial coat , maturation drying , storage and preservation , etc 摘要本文综述了近20年来植物人工种子研究的进展，并对人工种子的诸领域：概念、意义、动态、应用前景、体细胞胚的诱导与同步化、包埋方法、人工种皮、干化、贮藏及防腐等进行了概述。
The size and shape of the seeds , and the position of the hilum are of no important systematic significance , but the protruding degree of the hilum , the shape of the testa cells and the pattern of their cell walls , particularly the appendages of the in ner side , are of important value in the phylogenetic consideration of the tribe hyoscyameae 各属植物的种子大小、形状及种脐着生位置的系统学意义不大。但是，种脐突出与否、种子外种皮细胞形状和周壁式样，尤其是周壁内侧附属物等性状具有较大的分类学意义。
