Abstract

Propagation method of pineapple that can be developed to increase the number of seedling is crown leaf bud cuttings method. The level of fruit maturity is thought to affect the successfull of crown leaf bud cuttings. This study was aimed to obtain information about the effect of fruit maturity level when taking the crown for cutting material for pineapple cv. Smooth Cayenne seedling production. The experiment used a RCBD with one factor, the factor is the level of maturity with four levels of treatment: Level of maturity 1 (K1): all eyes were green; maturity 2 (K2): yellow fruit eyes <20%; maturity 3 (K3): yellow fruit eyes 40-55%; and maturity 4 (K4): yellow fruit eyes> 90%; but the reddish-orange color <20%. Each treatment was repeated five times, so there were 20 experimental units. The results showed that the levels of endogenous auxin and cytokines were not different at all levels of maturity stage, but the C / N ratio of K3 and K4 showed higher results. All maturity stage showed maximum bud formation at 4-6 WAP. The best fruit maturity level for pineapple seedling production with basal leaf crown cuttings is K4 (yellow fruit eyes> 90%, but reddish orange <20%). K4 had trend to produce higher survived, sprouted cutting and seedling dry weight. K4 showed the highest shoot dry weight and adequate seedling certification standards faster.
