Fig. 6From: Specific Streptomyces strain enhances the growth, defensive mechanism, and fruit quality of cucumber by minimizing its fertilizer consumptionThe effect of different quantities of NPK fertilizer and PGPR bacteria on some physiological characters. A Variation of Chla content of inoculated cucumber fruit. B Variation of Chlb content of inoculated cucumber fruit. C Variation of carotenoid content of inoculated cucumber fruit. D Variation of anthocyanin content of inoculated cucumber fruit. E and F Variation of total and reduced ascorbate content of inoculated cucumber fruit respectively. Values represent means of three replicates; bars represent standard deviation of the three replicates. Different levels of NPK fertilizers are a1 (50% = 1 g/L) a2 (75% = 1.5 g/L) and a3 (100% = 2 g/L) based on recommended amount of different growth levels of cucumber (vegetative growth, flowering and fruiting). Different letters within columns indicate significant differences according to Duncan’s Multiple Range Test (P ≤ 0.05)Back to article page
