Application of plant growth regulators PGR for improvement of tomato fruit set under high temperature growing conditions

Effyanti M. S., . and Mohd Razi I., . (2003) Application of plant growth regulators PGR for improvement of tomato fruit set under high temperature growing conditions. [Proceedings Paper]

Application of five treatments of plant growth regulators PGRTomat R75 ppm Benzylaminopurine BAP or BA 20 ppm 10 ppm Tomatlane and without PGR were given to a tomato variety. This experiment was conducted ad Hydroponics Unit UPM to study the effect of using different plant growth regulators on physiological and yield to the Beril variety F1 Hybrid. The plants were grown in a tunnel with temperature ranged between 24 - 41.5 degree. This experiment was conducted in complete randomized design: five PGR treatments with six replication. The PGR were applied directly to the open flowers in the early morning. The results of the study indicate that application of Tomat R 75 ppm BAP 20 ppm and Tomatlane improved the fruit yield by increasing fruit set shortened the days to maturity and large fruit. Based on the results it could be concluded that application of PGR will improve the fruit set and yield of tomato plants that were grown under high temperature.
