Abstract

Zat Pengatur Tumbuh (ZPT) adalah senyawa organik bukan hara, yang dalam jumlah sedikit dapat mendukung, menghambat dan dapat merubah proses fisiologis tumbuhan. Salah satu ZPT yang biasa digunakan untuk merangsang pertumbuhan tunas pada setek daun nanas adalah Benzil Adeno Purin (BAP) dari golongan sitokinin. Penelitian ini bertujuan mencari konsentrasi sitokinin untuk pertumbuhan setek daun nanas. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 6 taraf perlakuan Sitokinin dan setiap perlakuan ada 4 ulangan, setiap ulangan ada 5 sampel, sehingga terdapat 6 x 4 x 5 = 120 unit percobaan. Adapun perlakuan sitokinin  tersebut terdiri dari : s0 = tanpa pemberian sitokinin, s1 = 0,2 mg/l, s2 = 0,3 mg/l, s3 = 0,4 mg/l, s4 = 0,5 mg/l, s5 = 0,6 mg/l. Variabel yang diamati dalam penelitian ini adalah waktu terbentuknya tunas (hari), persentase terbentuknya tunas (%), tinggi tunas (cm), jumlah tunas (tunas), jumlah daun (helai). Hasil penelitian menunjukan bahwa pemberian berbagai konsentrasi sitokinin berpengaruh tidak nyata terhadap waktu terbentuknya tunas, tinggi tunas, jumlah tunas dan jumlah daun.

Abstract

Plant Growth Regulator (PGR) are non-nutrient organic compounds, which in small amounts can support, inhibit and can change the physiological processes of plants. On the PGR bosa used to stimulate shoot growth in pineapple leaf cutting is benzyl adeno purine (BAP) from the cytokines group. This study aims to find the concentration of cytokines for the growth of pineapple leaf cuttings. The design used in this study was a Completely Randomized Design (CRD) with 6 levels of Cytokinin treatment and each treatment had 4 replications, each replication had 5 samples, so there were 6 x 4 x 5 = 120 units of experiment. The treatment of cytokines consists of: s0 = without the administration of cytokines, s1 = 0.2 mg / l, s2 = 0.3 mg / l, s3 = 0.4 mg / l, s4 = 0.5 mg / l, s5 = 0.6 mg / l. The variables observed in this study were the time of formation of shoots (days), the percentage of shoot formation (%), shoot height (cm), number of shoots (shoots), number of leaves (strands). The results showed that the various cytokines concentration had non significant effect on the time of bud formation, shoot height, number of shoots and number of leaves.
