Abstract

In other to study the effects of different root zone temperature (RZT) and two STRAINs (Tehran and Zanjan STRAINs) on some grass-pea (Lathyrus sativus) varieties, an experiment was conducted in a controlled-environment chamber in air constant temperature 25°C. In this experiment, 3 varieties of grass-pea namely ardabil, shahrekord and zanjan and four root-zone temperatures included 5, 10, 15 and 25°C was evaluated as factorial with treatments organized following a randomized complete block design, with 3 replications. Result showed that there were differences among the grass-pea varieties for nodulation and nitrogen fixation, growth and development and dry weight. RZT enhancement increased nodulation and nitrogen fixation in varieties. STRAINs had different effect on measured traits of varieties, as that Inoculated plants with tehran STRAIN increased plant height, leaf number and area, nitrogen concentration in comparison with inoculated plants with STRAIN zanjan. Inoculated plants of zanjan and tehran STRAINs produced the most nodule number and nodule colonization number, plant nitrogen concentration and nitrogen fixation at 15 and 25°C RZT respectively.
