‘金帅’、‘双红’和‘富士’的直立新梢扭稍后当年成花率分别达74.4～77.9％、43.6～58.0％、28.7～32.4％,次年成花效果更好。‘金帅’、‘双红’、‘富士’的扭捎适期分别是春梢旺长期和旺长后期。‘金帅’直立新梢扭曲后,其下垂段叶片的净光合率在下降后不久又明显回升;其梢尖或顶芽中的磷素同化和核酸合成趋势逐渐增强;其中的~(32)p在缓慢通过扭曲部位、进入下垂段并逐渐增加后,又明显减少,最后保持一个较低的稳定水平。扭梢还加速了下垂段叶片和顶芽中过氧化物酶同工酶某些酶带的显现。 The annual turnover rates of ’Golden Delicious’, ’Double Red’ and ’Fuji’ were 74.4-77.9%, 43.6-58.0% and 28.7-32.4% respectively later, and the flowering rate in the following year was better. ’Golden Marshal’, ’double red’, ’Fuji’ twists and turns along with the appropriate period is the spring and spring Wang Wang long period and late. The net photosynthetic rate of its sagging leaves was significantly increased shortly after the twisting of ’Jin Shuai’ upright shoots, and the tendency of phosphorus assimilation and nucleic acid synthesis in its tip or tip bud gradually increased. The ~ (32) p slowly through the twist, into the sagging segment and gradually increased, then significantly reduced, and finally to maintain a lower level of stability. Phyllostachys korshinskii also accelerated the appearance of some bands of peroxidase isozymes in the sagging leaves and apical buds.
