佛手瓜胚胎育苗新法

传统的佛手瓜育苗,是采用完整的种瓜。在长达100天的催芽育苗过程中,种瓜易腐烂,并使胚胎变坏而丧失生命力。因此,用种瓜育苗的成苗率仅为40%~55%,而采用胚胎育苗的成活率则为80%~95%,且苗子生长健壮。

佛手瓜1个瓜内只有1颗种子胚芽。种皮与瓜肉紧密结合,不易分离,因此,传统育苗采用完整的种瓜催芽育苗。由于皮肉质膜状,在长达百天的催芽育苗过程中,种瓜易腐烂,染及胚胎变坏而丧失生命力。因此用种瓜育苗的成活率仅在40%~... 佛手瓜1个瓜内只有1颗种子胚芽。种皮与瓜肉紧密结合,不易分离,因此,传统育苗采用完整的种瓜催芽育苗。由于皮肉质膜状,在长达百天的催芽育苗过程中,种瓜易腐烂,染及胚胎变坏而丧失生命力。因此用种瓜育苗的成活率仅在40%~55%之间,而胚胎育苗的成活率则在... 展开更多

Understanding the embryo physiology of Hizikia fusiformis(Harvey) Okamura will promote the development of artificial seedlings. In this study, H. fusiformis embryos were cultured under different environmental conditions, including different temperatures(15℃, 20℃, and 25℃), sunlight intensities(100%, 50%, and 25% of full solar radiation) and types of UVR(UV-A and UV-B). Then, we determined the lengths, maximal quantum yields( Fv/Fm), and survival rates of the embryos. The results showed that the embryos had the highest lengths, Fv/Fm values and survival percentages when cultured under a temperature of 20℃ and 25% sunlight intensity. The full level of solar radiation severely reduced the growth and survival ratios of the embryos. Hizikia embryos recovered within 2 h from the damage caused by short-term(30 min) high radiation(about 70% of full solar radiation) and UVR exposure. However, the viabilities of the embryos were significantly decreased after 4 h exposure to UVR. According to these results, we propose that culture conditions with indoor natural light and room temperature would be favorable for the growth, development and physiology of H izikia embryos. 展开更多
