采用盆栽,设计CK(清水,T1);30 mg/L细胞分裂素(6-BA,T2);0.1 mg/L芸苔素内酯(BR,T3);40mg/L赤霉素(GA3,T4);30 mg/L 6-BA+0.3 mg/L BR(T5);50 mg/L 6-BA+0.1 mg/L BR(T6);10 mg/L 6-BA+0.5 mg/L BR(T7)共7个处理,考察对分蘖苗数、干物质积累、生长速率及净光合作用速率的影响。结果显示,T2处理显著增加分蘖数,比对照高16.7%,T4则比对照低近50%;同时T2和T6处理的干物质积累显著高于其他,T6地上部干物质积累速率最高,T3、T4最低;光合作用速率也以T2最高。结论,T2和T6处理可以较好促进分蘖的发生及营养生长期干物质积累,T4处理抑制分蘖明显,T3处理的浓度可能太高,对植株生长有一定的抑制作用,同时T2和T3存在互作效应,不同浓度复配对植株生长影响明显。
In the pot experiment, CK (water, T1), 30 mg / L cytokinin (6-BA, T2), 0.1 mg / L brassinolide (BR, T4); 50 mg / L 6-BA + 0.1 mg / L BR (T6); 10 mg / L 6-BA + 0.5 mg / L BR (T7) for 7 treatments. The effects of tillering number, dry matter accumulation, growth rate and net photosynthesis rate were investigated. The results showed that T2 treatment significantly increased the number of tillers, which was 16.7% higher than that of the control and T4 was 50% lower than that of the control. The dry matter accumulation of T2 and T6 treatments was significantly higher than that of the other treatments, T4 lowest; photosynthesis rate is also the highest T2. Conclusions: T2 and T6 treatment can promote the tillering and accumulation of dry matter in vegetative growth stage. T4 treatment inhibited the tillering significantly, and T3 treatment concentration may be too high, which could inhibit the growth of plants. Effect, different concentrations of plant growth significantly affected.
