甘肃马唧山地区榆中贝母(Fritillaria yuzhongensis)的生态学特性及种子发芽规律的初步研究

Fritillaria Yuzhongensis is a analogous short-lived plant which grows in the mountain region of Maxian mountain has a life period of about 100 days.The saed embryoes of mature fruits are hypoplastic with after-ripening characteristics, including both phases of morphological after-ripening and physiological after-ripening. Therefore, the seads treated at a given low-temperature can only complete after-ripening and be removed from dormancy. This study shows that the optimum temperature for fulfilling morpholo...
