Results showed that green firm callus and rooting were obtained with treatments of NAA 0.5-3.0mg/L, in which the NAA 0.5mg/L treatment appeared the optimal rooting result of 90%. White loose callus was obtained with treatment of 2,4-D0.1-3.0 mg/L.Callus can not be induced by adding BA solely at 0.5-3.0mg/L. There appeared bud redifferentiation only when appropriate concentration of combined BA,NAA and 2,4-D were applied.
结果表明:单独加入NAA0.5~3.0mg/L可诱导出绿色致密的愈伤组织,并再生出根,其中NAA0.5mg/L处理生根率最高,达90%;单独加入2,4-D0.1-3.0mg/L可诱导出白色疏松的愈伤组织;单独使用BA0.5—3.0mg/L不能诱导出愈伤组织;BA与NAA或2,4-D只有在适当的质量浓度范围内配合使用才能分化出芽,芽分化率最高的处理为BA3.0mg/L+NAA0.5mg/L,分化率为30%。

The daily total metabolic rates were determined for 31 fish with closed respirometers. In addition, resting daily total metabolic rates were determined for 20fish by confining the fish into a cage within the respirometer. The fish weighed 72.9-133.3g and were fed different ration levels from starvation to 4% bw / day at 25℃.
