Mean squares of different traits in 45 tomato genotypes during 2018 under normal and cold stress.
SOV: sources of variations; df: degrees of freedom; PH: plant height; SFW: shoot of fresh weight; SDW: shoot of dry weight; RFW: root of fresh weight; RDW: root of dry weight; PS: plant spread; FS %age: fruit set percentage; F/P: fruit percentage; SOD: superoxide dismutase; CAT: catalase.

* - P<0.05, ** - P<0.01 and n.s. - not significantly different at P=0.05. SOV: sources of variations; df: degrees of freedom; PH: plant height; SFW: shoot of fresh weight; SDW: shoot of dry weight; RFW: root of fresh weight; RDW: root of dry weight; PS: plant spread; FS %age: fruit set percentage; F/P: fruit percentage; SOD: superoxide dismutase; CAT: catalase.
