aInjury rating scale: 0 = consistent with control treatment, 0–30% = cotyledon and minority of functional leaves showed whitening, except new leaves, 30–60% = cotyledon, minority of functional leaves and newborn leaves showed whitening, 60–100% = majority of the plants showed serious whitening symptoms, some plant even necrosis, 100% = all plants showed whitening symptoms and necrosis. bSignificant differences between the two rates P < 0.05 level according to Fisher’s protected LSD test. *Significant; NS, not significant.
