THE EFFECT OF BAP AND THE LEVEL OF AGING STEM ON THE GROWTH OF PINEAPPLE (Ananas comosus (L) Merr) STEM CUTTING

A research was conducted to find out the effect of BAP and the level of aging stem on the growth of pineapple (Ananas comosus (L) Merr.) stem cutting from March to June 2009, at Indonesian Tropical Fruit Research Institute (ITFRI), Solok, West Sumatera. The experiment was arranged in factorial randomized block design with 5 replications. Two treatments applied were BAP (0; 100; 300; 500 ppm) and the level of aging stem (young stem; old stem). The Pieces of the stems was soaked into BAP solution in accordance with the treatment for 3 minutes and then dried. Based on the results of observation, it was found that all treatments have not significantly effect to all parameters. From the observation, it is also known that every stem cutting has the ability to produce shoots. Probably cutting requires longer time soaking BAP (> 3 minutes).
