Guano-Induced Germination and Responses of Wheat Seedlings to Guano Under Water Stress Treatments
Abstract
The present study was conducted to investigate the effects of guano (organic fertilizer) on
germination and growth parameters of wheat (Triticum durum L. Karakılcık). Guano was applied into
germination medium at a rate of 6g /100 ml - for 3 days. Following the germination of seeds, one
group was water stressed by applying a water deficit for 7 days and the other group was irrigated
ordinarily. The germination rate and the dry weights of germinated seeds were higher in guanoapplied
group. In vegetative stage, guano treatments improved relative water content (RWC) and
relative growth rate (RGR) under water stress. Water stress increased malondialdehyde (MDA) and
hydrogen peroxide (H2O2
) content but both parameters did not significantly change in combined water
stress and guano treatments. At the seedling stage, ABA (abscisic acid) content decreased in guano
group and under water stress but guano treatment increased ABA contents under water stress. It was
concluded herein that guano treatments improved germination and growth parameters of wheat seeds
and protected the wheat seedlings from oxidative damages under water stress.
