Abstract
An experiment was conducted during the wet season of 2010 to determine the effects of paclobutrazol on the lodging resistance, agro-morphological characteristics and yield performance of Elon-elon and Palawan red. Paclobutrazol was effective in shortening the length of the lower internodes which resulted to shorter plants but with increased lodging resistance. There was a reduction of 12.42 % on culm length and 9.59 % on plant height of the two varieties sprayed at 1000 ppm compared to the untreated plants. Lodging resistance increased with increased concentration of paclobutrazol and lodging index was described by the equation Y = -0.007x + 7.234. At all concentrations of paclobutrazol, Palawan red had the longest first and fourth internodes, heavier 1000 grain weight and higher leaf area index but with more unfilled grains per panicle than Elon-elon. On the other hand, smaller stem diameter, more productive tillers per hill and longer panicle length were obtained from Elonelon than Palawan red. Application of increasing concentrations of paclobutrazol did not affect the chlorophyll contents of the leaves at 15, 30 and 50 DAFS. The percentage filled grains/panicle, number of spikelets/panicle, weight of 1000 grains, dry matter yield, harvest index and grain yield were likewise unaffected owing to lodging at later stages of rice maturity.
