Abstract:
With three peppers as materials,using hydroponic method,from four aspects which were gas environment,temperature(15,20,25,30℃),light intensity (0,60,117 μmol·m-2·s-1),and collection time (1,2,3,4,5,6 h),collection method of collecting pepper root exudates were studied in pepper root.Meanwhile,as cucumber seedlings as receptor,allelopathy test of pepper root exudates that gathered by this method were conducted.The result showed that,at ventilation conditions,when the temperature was 20℃,light intensity was 117μmol·m-2·s-1 and collection time was 3 h,the amount of pepper root exudates were the most.Allelopathy of pepper root exudates on seedlings growth of cucumber manifested that low concentrations promoted and high concentrations inhibited.Therefore,this collection method could be used as a method of collecting root exudates of pepper.
