Study On Sprouting Characteristics Of Pinellia Ternata(Thunb.) Breit Seed

Pinellia ternata (Thunb.) Breit is perennial grass of Araceae. Pinellia ternata (Thunb.) Breit is the most commonly used Chinese medicine herb, which has the function of dry wet, convert phlegm, lowering athwart and stopping vomit, removing ruffian and dispeling vinculum, and is used in coughing, asthma, excessive phlegm, nausea, vomit.The growth and planting of Pinellia ternata (Thunb.) Breit is adaptable in Tianshui and Longnan district of our province. The planting of Pinellia ternata (Thunb.) Breit brings benign economic benefits to local farmers. Long-term gathering of wild tuber of Pinellia ternata (Thunb.) Breit dries up the wild resources in recent years. There is a shortage of tubers for planting in the market, the planting area decreases year by year, Pinellia ternata (Thunb.) Breit is losing the ability of sustainable development. So it is urgent to establish good breeding system to provide high quality tubers for production.Breeding with seed can effectively purify and rejuvenate cultivars, retain characteristics of spices.It also can improve the vigor of plant; prolong the period of the cultivars. We investigate the configuration of Pinellia ternata (Thunb.) Breit seed; analyze the environment condition needed during the germination process. Varying vigor is detected during the period of storage. Configuration and germinating process are discussed; we also articulate how temperature and hormone affect the germination of Pinellia ternata (Thunb.) Breit seed, how the storage method and storage time affect the longevity of Pinellia ternata (Thunb.) Breit seed. In doing so, we can find the effective way to protect germ plasm of Pinellia ternata (Thunb.) Breit, as well as ways to improve sprouting potentiality and sprouting rate. The result indicates that:The seed of Pinellia ternata (Thunb.) Breit has rigidity texture, the color of the seedcoat is reseda, the thickness of the seed is 0.1mm.The embryo is like spillikin and small, transparency and mucuslike, bigger on one end, there is no distinct differentiation of radical, embryo, cotyledon. Endosperm is harder, the sell is characterized as storage sell, and is used to store substances, the main storage substance is starch. The whole embryo is embedded in endosperm. The endosperm is the main body of the seed, accounting for 71.4%, the seedcoat 28.28%, the embryo 0.32%. The water moisture of mature Pinellia ternata (Thunb.) Breit...
