Effect of Different Pretreatments on the Germination of Zizyphus jujuba var. spinosa Seeds
JIANG Xue;Gansu Dunhuang West Lake National Nature Reserve Administration;
The seed hardseed percentage of Zizyphus jujuba var. spinosa is as high as 93.4%, natural conditions are difficult to germinate emergence, a certain processing can improve the seed germination rate, and this is advantageous to the production practice. The germinationg experiment of Zizyphus jujuba var. spinosa seed have different pretreatments, including stratification sprouting 20 days and 30 days, 60 ℃ and 35 ℃ warm water soak seed, seed soaking of sulfuric acid, 4% Na OH and 29% H2O2. The results showed that different pretreatment significantly improved the germination rate. Low temperature stratification 30 d used the sulfuric acid soaked seed 30 min, water soaked 24 h, then 60 ℃ water soaked 48 h, the seed germination of Zizyphus jujuba var. spinosa rate is the highest.
