马铃薯脱毒种薯的生理年龄直接影响田间出苗的早晚、苗数、整齐度、植株的生长势和产量。以鲁引 1号脱毒薯原原种为试材 ,研究了种薯不同生理年龄对产量和生育的影响 ,结果表明 ,老龄种薯出苗较早 ,生育进程较快 ,前期薯块膨大和产量积累较快 ,但后期表现出早衰现象 ,不利于高产。以生理年龄处于壮龄的种薯最好 ,出苗及时 ,光合效率高 ,能充分发挥其最大增产潜力。
Physiological age of potato virus-free seed directly affects the emergence of the field sooner or later, the number of seedlings, uniformity, plant growth potential and yield. The results showed that the seedlings of old seedlings grew earlier, the growth process was faster, the tuberous tubers were enlarged and the yield Accumulation of faster, but the late signs of premature aging phenomenon is not conducive to high yield. Physiological age in the seedling age of the best, timely emergence, photosynthetic efficiency, can give full play to its maximum yield potential.
