不同生态区蚕豆品种的光合特性研究

Research on Photosynthetic Property of Bean Variety in Different Ecology Region

通过对不同生态区蚕豆品种的生育进程、叶绿素含量、净光合速率、光合速率日变化以及产量构成因素等特性研究,表明攀西地区蚕豆与云南蚕豆的生态类型比较接近,生育期、产量及产量构成因素相近,攀西地区的蚕豆的叶绿素含量及净光合速率较云南蚕豆高,更能充分利用强光;阿坝、甘孜州蚕豆的生态类型与攀西地区蚕豆相差较大,偏向于春性品种,南移后生育期长, 植株高大,结实性差,叶片叶绿素含量及光合速率较高;成都地区的蚕豆表现为冬性较强,南移后, 虽能正常结实,但产量较低,对高原亚热气候区生态条件适应力较差。

By researching property on breeding process, chlorophyll content, photosynthetic speed rate, date change of photosynthetic speed rate and yield formed factors of bean variety in different ecology region, it shows that ecological type of bean in Panxi region and Yunnan is more similar, and breeding period, yield and yield formed factors are still similar. But chlorophyll content and photosynthetic speed rate of bean in Panxi region are higher than it in Yunnan, it can make full use of strong light. The ecological type of bean in A＇ba and Ganzi is more different from it in Panxi region, it is apt to spring variety, when moving to the south, its breeding period is long, its plant is higher, its fruits are not good and chlorophyll content in leaves and photosynthetic speed rate are higher. Bean in Chengdu region shows strong winter property, when moving to the south, it can get normal fruits, but yield of it is lower and its adaptation is bad for ecological condition of subtropical climate at highland.
