Sphenanthera (Schisandra sphenanthera Rehd. Et Wils.) Is Schisandraceae (Schisandraceae) Schisandra (Schisandra Michx.) Perennial deciduous woody vine, its dried ripe fruit called Kadsura. With China Schisandra medicinal value in the further development of the market demand increases every year, leading to over-harvesting sphenanthera, and even large-scale looting blue, cut fruit and other predatory vine taking collection, so wild sphenanthera resources have been greatly damage. In order to achieve wild sphenanthera sustainable use of resources, needed tending through wild and hatchery expand resources. Seed propagation is sphenanthera update one of the main species, seed dormancy directly affect the population update. In addition, through artificial breeding seeds Planting monthly, is an important means of bringing the wild. And sphenanthera long period of seed dormancy, germination rate their nursery work caused great obstacles. Therefore, the Central China Schisandra seed dormancy research is an important part of tending wild. In this paper, Shaanxi Zhashui wild sphenanthera as materials for different seed dormancy sphenanthera physiological and biochemical changes were studied, and the main conclusions are as follows: 1. Sphenanthera absolute moisture content of the seed with the seed and relative water content Sleep and finally reach a steady slow decline, Sand Section 169 d, the absolute moisture content and relative water content were 41.3 percent and 26.2 percent; sphenanthera seed moisture content during hibernation declined slightly, which will help to shorten or break dormancy and germination of seeds , provide a favorable growing material basis. (2) soluble sugar content increased with the continuation of seed dormancy decreased and then increased again showed a downward trend, Sand Section 169 d reaches a minimum; soluble protein content has been reduced with the seed dormancy, Sand decrease after the first 43 d increases, sand Tibet reaches a minimum of 169 d. 3 superoxide dismutase (SOD), catalase (POD), peroxidase (CAT), malondialdehyde (MDA) with seed dormancy showed regular changes, superoxide dismutase (SOD ), catalase (POD) and peroxidase (CAT) activity increased first and then decreased, respectively, in the first seed Sand 113 d, 85 d and 127 d reached the highest activity, followed by a gradual decline; C dialdehyde (MDA) content in the seed dormancy first and then decreased, the first 43 d Sand slow decline after reaching the maximum, sand storage section 169 d reduced minimum. 4 seed dormancy in sphenanthera interim (seed Sand Section 43 d ~ 85 d), gibberellic acid (GA3) content decreased first and then increased the trend; abscisic acid (ABA) content tends to decrease overall; zeatin nucleoside (ZR) content of a larger growth.
