Abstract

The number of developing fruits retained on the female parent after crossing influenced not only seed yield, but also quality of seeds harvested. Plant growth regulators play a key role in controlling internal mechanisms of plant by interacting with key metabolic processes such as, nucleic acid metabolism and protein synthesis. Use of the growth regulators (PGRs) might be a useful alternative to increase crop production. Looking to these, the study was conducted with an aim to study the effect of fruit load per plant viz., L1: Four crossed fruits per plant, L2: Six crossed fruits per plant, L3: Eight crossed fruits per plant, and L4: All crossed fruits per plant and growth regulators viz., G1: GA3 @ 50 ppm, G2: NAA @ 80 ppm and G3: Control (No spray) on fruit set, seed yield and quality of brinjal hybrid GJBH 4.

Conclusion

Fruit load per plant and plant growth regulators played an important role on seed yield per plant and quality of brinjal hybrid seeds after the harvest of seeds. Irrespective of plant growth regulators, retention of four crossed fruits per plant noted significantly the higher values for yield attributing components and seed quality parameters. But, seed yield per plant found to be the highest in all crossed fruits per plant because of maximum numbers of fruits. Similarly, irrespective of fruit load, foliar spray of GA3 @ 50 ppm at fruit initiation stage produced significantly the higher seed yield per plant, yield attributing components and seed quality parameters Among the different combinations of fruit load per plant and plant growth regulators, retention of four crossed fruits per plant and foliar spray of GA3 @ 50 ppm at fruit initiation stage (L1 x G1) was found to the best combination, as it having the maximum fruit weight with the highest test weight and different seed
