Paclobutrazol For Vegetables Growing

Paclobutrazol is applied to plants and crops for increasing yield and quality.
The Plant Growth Regulator Paclobutrazol, a triazole derivate, inhibits gibberellic acid biosynthesis, and has been shown to shift assimilate partitioning from leaves to roots. It also increases the carbohydrate, soluble protein and mineral levels in leaf tissue.The translocation of Paclobutrazol from the root is primarily through the xylem
Paclobutrazol inhibits internode extension and frequently improves fruit set and yield. It also retards the growth of grasses.
Stem elongation in bean and chrysanthemum was reduced by Paclobutrazol and in rice it reduced stem length and lodging
Soil application was in most experiments more effective than foliar application and drench was more effective than spray. The effectiveness of the soil drench indicates that the chemical is readily translocated in the xylem. However, chemical taken up by the leaves would have to move through the phloem at least to the stem where it might translocate to the xylem
