aThe data on SV, LG, LSP, LSW, LL, LW, LA and SG were recorded at 5th leaf stage of seedlings. The data on SV, LG, LSP and LSW were recorded on the scale of 1–5. LG was evaluated in the early morning hours when there was maximum reflection of light from the leaf surfaces whereas the observations on LSW were recorded between 7.00 to 7:30 A.M
bCD: Critical difference
cCV: Coefficient of variation
d± Value is standard error of difference
