Differential responses of two fenugreek (Trigonella foenum-graecum L.) landraces pretreated with melatonin to prolonged drought stress and subsequent recovery

Table 1 Summary of variance analysis to determine whether there are statistically significant differences among the treatments (SC, SD, SM, VC, VD, and VM) regarding the measured parameters in the responses to prolonged drought stress and subsequent rewatering
