垦稻系列水稻品种发芽特性研究

试验选取黑龙江省农垦科学院水稻研究所选育并已大面积推广种植的7个品种进行发芽试验,根据调查数据分析,在确定参试种子能发芽的前提下,试验的7个品种在发芽速度、出根速度、芽长、根数、根形等方面均有较大差异,充分体现了不同品种间不同的发芽特性,在试验过程中,7个品种的发芽速度根据不同品种间的萌发特性,适度改变育苗模式进行生产。

Study on the Germination Characteristics of Kendao Series Rice Varieties

Germination trial was carried out on 7 rice varieties bred by Rice Research Institute of Heilongjiang Academy of Land Reclamation Sciences which were cultivated at present. On the premise of germination the conclusion was drew by analyzing survey data, there was great difference on germination speed, root speed, shoot length, root length, root number, root shape of the 7 rice varieties. Germination characteristic difference of different varieties was reflected. Different seedlings methods could be taken according to difference of rice varieties.
