6-苄氨基嘌呤对水涨龙眼花芽分化的效应
Effects of 6-Benzylaminopurine on the Flower-Bud Differentiation of “Shuizhang” Longan

摘要: 6-BA25—100ppm11月下旬处理水涨龙眼,对小年树的花芽分化有一定的效应,植株的花穗抽生率,随着处理浓度的增加而提高,高浓度(10 ppm)处理有明显的促花效应(P≤0.05)。大年树处理后花穗抽生率与对照相比无明显差异。所有处理对大年和小年的花穗、夏梢和秋梢结果母校的生长发育均未见不良影响。Abstract: 6-Benzylaminopurine at 25-100 ppm was applied to "Shuizhang" longan trees in late-November. Results showed that this practice has effects on the flower-bud differentiation in off-year. Flower cluster rate increased with the increase of 6-benzylaminopurine concentrations. The high concentration (100 ppm) has a significantly primotive effect on flowering (p≤0. 05). However, 6-benzylaminopurine had no obvious effect in on- year. All treatments have no unhealthy effect on the development of flower cluster, summer shoots and autumn shoots.
