Passion Fruit Quality under Acidic Soil Conditions
Passion Fruit Quality under Acidic Soil Conditions

Deficiencies in these minerals may have led to a low photosynthetic rate and SPAD index ,under, the higher pH ,condition,. With excessive ,acidic, soil (pH 3.5), vegetative growth, photosynthetic rate, and the number of flowers were as high as those at pH 4.5, although the fruit-set percentage and fruit quality were lower.
