Chlorophyll a (a,b), b (c,d), and total (e,f) of sour passion fruit cv. BRS GA1 under irrigation depths, pit volumes of and, different doses of water-retaining polymer. Means with same lowercase letters do not differ in irrigation depths of 70% and 100% ETc within the same dose of the water-retaining polymer and the pit volume according to the Tukey test (p > 0.05), and means with same uppercase letters do not differ in pit volumes of 64 and 128 dm3 within each dose of water-retaining polymer and irrigation depth according to the Tukey test at 0.05 probability.
