Abstract

The reduction of salt toxicity in the soil environment significantly contributes to the growth and development of plants. In this study, tolerance and development status of strawberry plant were investigated through irrigation solution including 50 mmol L-1 NaCl salinity and the application of 50 mg L-1 humic acid (HA). The physiological and biochemical parameters in vegetative and fruit stages and the mineral contents of strawberry plants were assessed if application of HA contributed to salt tolerance mechanisms of strawberry plants. HA improved physiological parameters such as crown and root fresh weight, crown and root dry weight, stomatal conductance as well as improving biochemical parameters and reducing stress metabolites such as (total chlorophyll contents, proline, malondialdehyde, catalase, and peroxidase enzyme activities). HA application (50 mg L-1) under salt stress (50 mmol L-1) also improved the quality parameters such as vitamin C and lycopene contents. We suggest that HA application is beneficial via increasing the tolerance mechanisms of salt-sensitive strawberry plants.

Özet

Topraktan tuz toksisitesinin azaltılması, bitkilerin büyüme ve gelişimine önemli katkılar sunmaktadır. Bu çalışmada 50 mmol L-1 NaCl içeren sulama suyu ile sulanan çilek bitkisinin 50 mg L-1 hümik Asit (HA) uygulaması ile tuz stresine karşı toleransı ve gelişim durumu araştırılmıştır. Çilek bitkilerinin tuz toleransına HA uygulamasının katkıda bulunup bulunmadığı, vejetatif ve meyve aşamalarında fizyolojik ve biyokimyasal parametreler ve çilek bitkilerinin mineral içerikleri değerlendirilmiştir. HA, taç ve kök taze ağırlığı, taç ve kök kuru ağırlığı, stomatal iletkenlik gibi fizyolojik parametri ve bunun yanı sıra artan biyokimyasal parametreler ve azalan stres metabolitleri ile (toplam klorofil, prolin, MDA, katalaz ve peroksidaz) bitki gelişimini sağlamıştır. Tuz stresi altında (50 mmol L-1) HA uygulamasının 50 mg L-1 vitamin C likopen gibi kalite parametrelerini artırdığı belirlenmiştir. HA uygulaması tuza hasas olan çilek bitkisinin tolerans mekanizmasını artırarak fayda sağlamıştır.
