Chemical composition and herbicidal potent of Cauliflower and Cabbage turnip
Journal Title: Scientia Agriculturae - Year 2016, Vol 14, Issue 2
Abstract
This study was conducted to evaluate the phytochemical content and allelopathic potential of two cabbages varieties, ie. Cauliflower (B. oleracea var. Botrytis) and cabbage turnip (B. oleracea var. gongylodes). Their aqueous and organic extracts were evaluated on lettuce (Lactuca sativa L.) and one of the most dominant weeds in Tunisia, nettle-leaf goosefoot (Chenopodium murale L.). Field experiments were conducted to evaluate the smothering potential of the two varieties. The total phenolics, flavonoids, flavonols and flavones, alkaloids and proanthocyanidins contents were higher in the aqueous extracts of both varieties. Whereas, for organic extracts, petroleum ether and methanol cauliflower extracts and chloroform and methanol cabbage turnip extracts were the richest ones. All aqueous and organic extracts significantly delayed germination, reduced its rate and affected seedling growth. Reduction of germination and growth were more important at the higher concentrations and in presence of cabbage turnip extract. The organic extracts of both varieties have significantly inhibited the seedling growth of target species, especially petroleum ether, and methanol cauliflower extracts and chloroform and methanol cabbage turnip ones. Field experiment highlighted the smothering potential of the twice varieties, and confirmed the higher allelopathic potential of cabbage turnip as compared with cauliflower.
