Daily Changes of Photosynthetic Rate on Strawberry in Greenhouse of Cold Region

摘要：

By using the open exchange system LI-6400 Portable Photosynthetic System, the photosynthetic rate and their influence factors of siji strawberry in greenhouse were studied. Daily change of Net Photosynthetic Rate in Strawberry appears double peaks curve. The photosynthetic rate in greenhouse is higher than that in open field. Photosynthetic rate has significant correlation with the environmental factors, like photosynthetic effective radiation, temperature and relative humidity; Photosynthetic rate has significant correlation with plant vegetative factors, like stomata conductance. If stomata conductance increases, photosynthetic rate increases, and conversely it will decrease. The result can provide theoretical basis for further study on Strawberry in greenhouse.
