Effects of Mulching with Hyperaccumulator Straw on Photosynthetic Pigment Contents in Grape Seedlings under Cadmium Stress
Year: 2018
Type: conference-paper
Abstract: To study the effects of mulching with straw of different cadmium hyperaccumulators (Crassocephalum crepidioides, Galinsoga parviflora, Youngia japonica and Gnaphalium affine) on photosynthetic pigment contents in grape seedlings was conducted by a pot experiment under cadmium stress. The results showed that mulching with straw of C. crepidioides and G. parviflora increased the content of chlorophyll a and total chlorophyll of grape seedlings. All the straw-mulch treatments increased the chlorophyll b content of grape seedlings, and the chlorophyll a/b for all the treatments had no significant difference. Except mulching with Y. japonica reduced the content of carotenoid, other straw-mulch treatments increased the carotenoid content of grape seedlings. Especially, mulching with G. parviflora significantly increased the content of chlorophyll a , chlorophyll b , total chlorophyll and carotenoid, with a increasing of 40.60%, 47.85%, 42.80% and 47.79%, respectively. In conclusion, mulching with G. parviflora straw could increase photosynthetic pigment contents of grape seedlings under cadmium stress.
