Abstract
Through germination experiment in the laboratory, allelopathic effects of rape(Brassica campestris) root exudates on seeds activities, seedlings growth and physiological-biochemical characters of wheat, rape, faba-bean and maize have been studied. The results showed that the addictive effects of rape root exudates had significant influences to seeds germination percentage, shoot fresh and dry weight, root fresh and dry weight, peroxidase (POD) activities, malondialdehyde (MDA) content and root activities in seedlings of the different 4 crops. The allelopathic effects of rape root exudates were the weakest to wheat seedlings, and they had a promoting effect on germination percentage, root length, shoot dry weight, POD activities and root activities of wheat and biological destroyed degree of cells membrane in seedlings of all crops, but had an inhibition effect on other growth characters of wheat and all growth characters of rape, faba-bean and maize seedlings. It was concluded that the allelopathic effects of rape root exudates had different selectivity on different crops and different growth characters. Therefore, the key planting techniques for high quality and output of rape are adopting correct intercropping and rotating of crops.
