Table 1 Effects of different R: FR values on plant height, stem diameter, fresh and dry weights of root, stem, and leaf in tomato seedlings under salinity stress in wild type (WT) and phytochrome B1 mutant (phyB1 mutant)
From: Exposure to lower red to far-red light ratios improve tomato tolerance to salt stress
