Abstract
Variability of pineapple seeds tissue culture result through gibberellins application
and nitrogen fertilizer to the leaves. Elfiani and Vivi Aryati. One of the problems in
pineapple cultivation in Indonesia is unavailable seeds producer who provide variety pineapple seeds, whether in its form or in it’s nature, with major quantity and short relative time. The aims of this research is to study the impact giving Nitrogen fertilizer to the leave, gibberellins and time application through the development pineapple seeds tissue culture result. The field study is held at the Center Tropical Fruits Research (PKBT), research institution and human resources (LPPM) IPB, Baranang Siang, Bogor. It was started in August until December 2010. This research used factorial random design. The first factor is time application consist of two standards, in the morning (W1) and at night (W2). The second factor is gibberellins concentration consist of three standard, 0 ppm (G0), 50 ppm (G1), 100 ppm (G2). The third factor is N fertilizer dose consist of three standard 0 g/I (N0), 0.5 g/I (N1), 1.0 g/I (N2). There are 18 combination treatments with three repetitions with the result 54 experiment units. Each unit consists of 10 pineapple plantlet, with the result 540 experiment. Fertilizer distribution 0.5 g/I
increase the plant high, the number of the leaves, and the width of the leaves, wet
weight and dry weight. Giving extra Nitrogen can reduce the development of the pineapple seeds tissue culture result. Giving gibberellins and time application cannot increase the development of pineapple seeds tissue culture result.
