Abstract

The study examined photosynthetic efficiency of two barley landraces (cvs. Arabi Abiad and Arabi Aswad) through a prompt fluorescence technique under influence of 14 different abiotic stress factors. The difference in the behavior of photosynthetic parameters under the same stress factor in–between cv. Arabi Abiad and cv. Arabi Aswad indicated different mechanisms of tolerance and strategies for the conversion of light energy into chemical energy for both the landraces. This study confirmed the suitability of some chlorophyll fluorescence parameters as reliable biomarkers for screening the plants at the level of photosynthetic apparatus.

Highlights

In this fast growing world, increasing productivity of the agricultural areas is a main objective of agronomical planners with a need of more productive and better adapted plant varieties to achieve it
Transient fluorescence curves: Transient fluorescence curve for 14 abiotic stress factors on barley landraces were drawn for two time intervals of 1 and 7 d of treatment (DOT)
In order to visualize better the influence of different abiotic stress factors on barley landraces, the curves were plotted as the ratio of relative fluorescence at time t (Ft) to relative fluorescence at time 0 (F0)

Summary

Introduction

In this fast growing world, increasing productivity of the agricultural areas is a main objective of agronomical planners with a need of more productive and better adapted plant varieties to achieve it. Research on plant phenotyping is performed all around the world in order to make crop improvement efficient (Walter et al 2015, Lootens et al.2016). Plant phenotyping is a process which requires deep knowledge of plant physiology. Photosynthesis is always considered to be a good measure of overall performance in plants. It is the only energy input in plants and thereby impacts all aspects of plant metabolism and physiology.
