• 摘要： 种子萌发除了需要充足的水分和足够的氧气以外还需要适宜的温度。温度是植物种子萌发和出苗的基本条件之一，温度过高或过低会影响种子活力，造成发芽和出苗不良，而发芽势、发芽率、发芽指数和活力指数则是直接衡量种子发芽好坏的重要指标。不同低温处理对多油辣木种子的萌发率和出苗率有着明显影响，随着处理温度的降低，幼苗生长速度随之减慢，本实验通过设置不同的温度处理，探索温度对多油辣木种子的萌发率和出苗率的影响，寻找适宜多油辣木种子萌发和出苗的最佳温度，促进辣木的优质培育，达到速生丰产的目的。
• In addition to adequate water and oxygen, seed germination requires the proper temperature. Temperature is one of the basic conditions for seed germination and seedling emergence. Too high or too low temperature will affect seed vitality and cause poor germination and seedling emergence. Low temperature treatment on many different between seed germination rate and germination rate has a significant effect, with the loss of the processing temperature, seedling growth rate slows, then the experiment by setting the different temperature treatment, exploring the temperature of between seed germination rate and germination rate, the influence of looking for suitable between wood seed germination rate and the best temperature is the highest germination rate, promote the moringa quality cultivation, achieve the goal of fast-growing fertility.
