QUALITY ENHANCEMENT OF TOMATOES (Lycopersicum esculentum Mill.) USING GIBBERELLIC ACID (GA) FROM VARIOUS PLANT MATERIALS

Tomato (Lycopersicum esculentum Mill.) is a fruit with many benefits. Plant growth regulators (PGRs) prove effective in improving the quality and production of tomatoes. Gibberellic Acid/GA PGR that stimulates process flowering, parthenocarpy, carbohydrate mobilization during germination influences other plant physiological aspects. However, because synthetic GA costly, numerous natural ingredients have been proposed as its source, for example, bamboo shoots, vegetable ferns, corns, shallots can improve This study aimed to determine role from various extracts on tomatoes, providing recommendations best extract It was conducted experimental garden at Agronomy Horticulture Laboratory, Physiology Laboratory Faculty Agriculture, Food Analysis Agricultural Technology, Udayana University. research compiled using Randomized Group Design consisting one factor, i.e., type five settings four repetitions. The tomato treatments were E0 = no sprayed, BE sprayed shoot extract, VE fern OE onion CE corn extract. results showed gibberellins significantly affected diameter, thickness, total sugar content tomatoes obtained by applying source gibberellins.
