Allelopathic effects of redroot pigweed (Amaranthus retroflexus L.) root exudates on common bean seedling growth
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2012, Vol 3, Issue 6
Abstract
The study was conducted to evaluate the allelopathic effects of redroot pigweed (Amaranthus retroflexus L.) root exudates on seedling growth of common bean (Phaseolus vulgaris L.) cultivars. The study was arranged in a factorial experiment based on randomized completely block design (RCBD) with four replications. The factors were three common bean cultivars including Akhtar, Daneshkade and Khomein, redroot pigweed densities at 0, 4, 8, 16, 24 and 32 pre-germinated seeds in each beaker and redroot pigweed growing time at 3, 6, 9 and 12 days. Results indicated that the effects of common bean cultivar, redroot pigweed seed d nsity and growth time were significant on common bean root and shoot length. The redroot pigweed growing time of 6 days and densities of 16 and 24 plants per beaker had the greatest inhibitory effect on common bean root and shoot length. Also the redroot pigweed had the greatest inhibitory effect on seedling growth of cv. Daneshkadeh.
