چکیده

The objective of the present study was to investigate the impact of foliar application of putrescine and humic acid on the qualitative traits of strawberry plant cv. Camarosa in soilless culture. The experiment based on completely randomized block design included foliar application of putrescine at five levels (0, 0.5, 1, 2, 3, 4 mM) and humic acid at four levels (0, 10, 20 and 40 mgl-1). To carry out the experiment, totally, 20 treatments with 3 replicates (blocks), each replicate consisted of 2 pots (each pot containing one plant) and hence a total of 120 plants were used. Foliar spraying of the chemicals was done five times; 3 and 5 weeks after transplanting, at onset of flowering and first and third week after fruit setting. The results showed that foliar application of putrescine significantly increased total soluble solids of fruit and humic acid reduced fruit titrable acidity insignificantly. It seems that if humic acid is used at higher concentrations or mainly in vegetative period may be more effective in improving various qualitative characteristics of strawberry fruit.
