Effect of invasive plant Solidago canadensis L. on photosynthetic physiology of wheat

Abstract

Abstract: Invasive plant Solidago canadensis L. and the native plant Solidago decurrens Lour. were used as donor plants, and wheat was employed as a receiver to study the effect of the solutions containing water extracts from the two different donors on photosynthetic physiology content of wheat receiver. The result showed that the specific solutions containing water extracts from Solidago canadensis L. and Solidago decurrens Lour. significantly decreased Chlorophyll content, changed fluorescence induction kinetics parameters of Chlorophyll a, and in turn reduced photosynthetic efficiency. The solution with water extracts from invasive plant Solidago canadensis L. inhibited photosynthetic physiology of wheat leaves more seriously than that from native plant Solidago decurrens Lour.
