Results are expressed as mean value±standard error. Values with the same letter within the column are not significantly different at p<0.01 according to Tukey’s HSD test. *Statistically significant factor at 99% confidence level. 1=early flowering stage (May, 2019), 2=early fruiting stage (August, 2019), 3=late fruiting stage (October, 2019)
