Abstract:

Poliploid is an attempt to obtain new variants by manipulating the number of chromosomes from diploid (2n) to polyploid using the seed immersion method of cayenne pepper 2n for 30 days at colchicine concentrations of K0 = 0,0% (control); K1 = 0,1%; K2 = 0,2%; and K3 = 0,3%. Data were analyzed by using analysis of variance. Results of analysis of variance indicated that there were highly significant effect of colchicine concentrations on the entire observed variables. Percentage of seed germination in 0.0% of colchicine was 92.20% with the number of chromosomes 24 (2n) and in 0.1% of colchicine was only 26.20% with the Number of chromosomes 48 (4n). The increase in colchicine concentration to 0.2% to 0.3% had a lethal effect on the immersed seeds and no seed germination occurred (0,00%). The growth of cayenne pepper post immersion in colchicine resulted in a large stem diameter, a large number of branches, a small number of leaf, a greater chlorophyll content, a large number of stomata, a small leaf area, a shorter flowering age, glossy in fruit color, shorter fruit maturity, a longer size of fruit stalk, longer fruit size, bigger fruit diameter, heavier fruit weight, the number of fruit harvested, heavier fruits harvested, higher number of seeds per fruit, and weight per 100 seeds when compared with control plants (K0 = 0,0%).
