马铃薯种薯芽龄(种薯萌芽时间)影响种薯的生理年龄。根据不同芽龄种薯芽条形态解剖,种薯生理变化及植株形态生理,产量形成等方面的研究。结果表明,芽条发育程度,芽生长锥分化程度与芽龄大小成正相关,种薯内的生理变化、植株生长发育、生理兴衰变化、产量形成等与种薯芽条发育程度,特别是芽生长锥分化程度呈显著相关。芽条生长锥分化程度相近的种薯,具有相近的生理效应。
Potato seedling age (seed germination time) affect the physiological age of seed. According to the morphological and anatomical characteristics of potato buds at different budding ages, the physiological changes of seed potatoes and plant morphology and physiology, yield formation and other aspects of the study. The results showed that the degree of budding development and the differentiation degree of shoot growth cone were positively correlated with the budding age. The physiological changes, the growth and development of plants, the changes of physiology, the formation of yield, and the development of seed buds, especially bud growth Cone differentiation was significantly correlated. Bud growth cone similar to the degree of differentiation of seed, with similar physiological effects.
