The allelopathics effects of the aqueous extract of wonnseed goosefoot (Chenopodium ambrosioides L.) on germination of the tomato seeds (Lycopersicum esculentum Mill).
Abstract
A study was conducted to evaluate the effects of aqueous extracts from leaves and fruits of Chenopodium ambrosioides, on the percentage and rate of germination of tomato seeds (Lycopersicon esculentum). Each experimental unit was represented by a Gerbox box. Treatments had been constituted by the aqueous extract concentrated (100%) or diluted with distilled water, in the concentration of 25, 50 and 75% v/v, using distilled water as the control. The lesser percentage of accumulated germination was verified in the boxes that had received extract 100% and 75% v/v that they had been also the ones that had required greater average time of germination and minor average rate of germination.
