Effects of Monopotassiumphosphate and Ethephon on Flowering of Litchi (Litchi sinensis Sonn.) cv. Nakorn Phanom 1

Abstract

The effects of 1 percentage monopotassiumphosphate and 800 ppm. ethephon on branching of litchi cv.
Nakorn Phanom 1. The experiment was conducted on randomized complete block design; sprayed with tap water
(control), 1 percentage monopotassiumphosphate, 800 ppm ethephon. and 1 percentage of monopotassium
phosphate and ethephon 800 ppm. The result revealed which the number of shoots had no different significance
before and after spraying with monopotassiumphosphate 1 percentage and monopotassiumphosphate 1
percentage and ethephon 800 ppm. The ethephon 800 ppm could promote the length of leaves, that had
statistically different significance. All treatments had no flowering. Thus, after hard prunning in one year and
chemical spraying could not promote flowering.
