1.子叶展开阶段辣茭最初子叶面积大,表明生育明显地被促进。子叶小、细长,是由于温度高,如果同时日照弱,更助长这种趋势,胚轴也长,子叶早期黄化脱落。相反,昼夜温差大,夜温稍偏低时,子叶宽大,胚轴长3厘米左右,健壮。2.花芽分化阶段真叶展开2片,第3片开始展开时,内部形成花芽,进入生殖生长期,并同时开始分枝。分枝数一般是2个,也有3个的。夜温低易发生3个分枝。也有一部分植株由1个侧枝和2个分枝结合的不完全分枝。在较低温度
1. Cotyledon phase spicy Tui cotyledon initial large area, indicating that fertility was significantly promoted. Cotyledons small, slender, is due to the high temperature, if at the same time weak sunlight, but also to promote this trend, the hypocotyls are long, cotyledons early yellow shedding. On the contrary, when the temperature difference between day and night is large and the night temperature is slightly lower, the cotyledons are large and the hypocotyls are about 3 cm long and strong. 2. Flower bud differentiation stage true leaf expand 2, the first three began to expand, the internal formation of flower buds, into the reproductive growth period, and at the same time began to branch. The number of branches is generally 2, there are 3. Low night temperature prone to three branches. There are also some plants that are not completely branched by 1 branch and 2 branch. At lower temperatures
