THE UTILIZATION OF THE LOG-LINEAR MODEL OF THE R譙 CONTINGENCY TABLE IN AGRICULTURAL EXPERIMENT ANALYSIS

This paper presented the log-linear model of the rxs contingency table to be used on the analysis of the effects of plant growth regulators which were used in the female flowers blooming of cv. Lantek Litchi.The crowns were sprayed with GAS, NAA, 2,4-D and tri acontanol for raising fruit setting percentage. When 20 days after treatments the results showed very significant differences among the levels of NAA and 2,4-D, but hadn’t shown difference among the levels of GA3 and triacontanol. Compared with CK, GA3, NAA, and 2,4-D came up to very significant difference for raising fruit setting percentage except NAA 5 ppm and 2,4-D 5 ppm, and triacon-tanol came up to very significant negative levels. When 40 days after treatments,no significant difference among the levels of each regulators were observed. The results compared with CK had shown NAA and GA3 came up to very significant levels for raising fruit setting percentage, 2,4-D came up to significant levels except 5 ppm, but triacontanol reduced fruit setting percentage and didn’t come up to significant levels.
