Little seed canary grass (Phalaris minor Retz.) promoting own growth functional traits but suppressing of wheat crop (Triticum aestivum L.) at vegetative stage: An ecological assessment
Journal Title: Annals of Plant Sciences - Year 2017, Vol 6, Issue 11
Abstract
Weed-crop interaction in the agro-ecosystems is a serious biological concern which hampers production and yield of the crops. Present study conducted to assess growth functional traits of selected weed and crop species under weed-crop interaction experiment that was established in a Latin square matrix model (LSM) in the backside of Department of Botany in a fenced dome. We investigated the ability of little seed canary grass that how it suppresses wheat crop growth at vegetative stage under mono- and mixed culture combinations. Data sampling for selected growth traits (Shoot height, Leaf area and Tiller number) were monitored at different temporal days after seed sowing (30-, 60-, 90- and 120 DAS). Results indicated that at initial stage (30 DAS), wheat exhibited significantly better growth (more leaf area and shoot height than little seed canary grass) under both combinations (Mono- and Mixed culture); however, little seed canary grass (Phalaris minor) suppressed both traits of wheat (leaf area and shoot height) due to interspecific competition. After 30 DAS, however little seed canary grass switched own growth traits in increasing mode therefore shoot height and leaf area were increases till 120 DAS, while, growth traits of wheat crop was significantly suppressed. Since, a linear trend was observed in the growth traits particularly shoot height with respect to days after sowing. Therefore, a significant relationship between growth traits and days was developed under both combinations that evidently indicated impact of little seed canary grass on suppression of wheat crop. In conclusion, wheat crop growth seriously undergo suppression due to little seed canary grass as inter-specific competition at least from initial stages of growth while growth traits of little seed canary grass less affected in competition which may be act as facilitation for weed under weed-crop interactions.
