甘蔗的苗期生长,一开始就要求与自身相适应的自然环境。而气候环境条件对其生长发育的影响是关键性的因素,在目前提倡节种育苗工作中,有必要谈谈甘蔗苗期阶段生理上对气候的要求,供参考。一、甘蔗发芽成苗阶段发芽是有机体的一种复杂的内部生理变化,水份是促进生物体内部生理变化的基础,无性繁殖用的蔗种(包括芽片、蘖芽、蔗头芽) Sugarcane seedling growth, from the outset requires its own adaptation to the natural environment. The climatic and environmental conditions on its growth and development are the key factors in promoting the current section of seedling breeding, it is necessary to talk about the physiological requirements of sugarcane seedlings stage for the climate for reference. First, the stage of seedling emergence Sugarcane germination is a complex internal organism physiological changes, water is to promote the physiological changes within the body of the foundation, asexual use of sugarcane species (including shoots, tiller buds, sugarcane head)
