油茶物种可分春花种和冬花种二大类。对花期不同的油茶物种、品种进行杂交育种时,必须搞好花粉贮藏,以保持花粉的生活力。为了正确判断花粉生活力,对影响花粉生活力的几个因素,如培养基配方、采粉时间、播种密度等与花粉发芽及花粉管生长作 Camellia species can be divided into two types of spring flowers and winter flowers species. For the hybridization of Camellia species and varieties with different flowering periods, pollen storage must be well done to maintain the viability of pollen. In order to correctly judge the pollen viability, several factors that affect pollen viability, such as medium formula, time of harvesting, sowing density, and pollen germination and pollen tube growth
