Abstract

The sweet orange, scientifically labeled as Citrus sinensis L. and belonging to the Rutaceae family, holds significant global importance as a fruit. While its origins trace back to Southeast Asia, it is now cultivated in various regions across the world. Its pulp and the juice extracted from it are essential components of diets, rich in vitamin C, liminoids, synephrine, hesperidin, polyphenols, pectins, calcium, potassium, thiamine, niacin, and magnesium. A systematic study was carried out to investigate the Effect of Different Levels Gibberellic acid on Seed Germination and Seedling Growth of Sweet Orange (Citrus sinensis L.) cv. Malta. The experiment was allocated with three replication and each replication contained 15 seeds under a randomized complete block design with 11 different treatment combinations of GA3. The best results in terms of minimum days taken for germination, maximum germination per cent, survival per cent, shoot length, shoot diameter, number of leaves, leaf area, shoot fresh weight, shoot dry weight, root length, root diameter, total number of roots, root fresh weight, root dry weight, total fresh weight, total dry weight and cost benefit ratio were obtained with T11 (GA3 @ 200 ppm). The goal of this study was to determine how Gibberellic acid influences seed germination with different concentrations and which concentration is best or suitable for further future applications to grow seedlings easily and quickly.

Conclusion

In the present investigation, it was concluded that GA3 @ 200 ppm (T11) was proved superior in respect to germination of Sweet Orange (Citrus sinensis L.) cv. Malta seed as well as growth parameter, survival percent, shoot characters, root characters, total fresh weight, total dry weight and maximum cost benefit ratio was also observed in it (1:5.173).Future scope the seed treated with GA3 200ppm identified in this study can be recommended commercially for overall growth of seedlings and Cost benefit ratio for Sweet orange cv. Malta.
