PENGARUH PEMBERIAN IBA (Indole Butyric Acid) DAN KONSENTRASI NAA (Naphthalene Acetic Acid) TERHADAP KEBERHASILAN PENYETEKAN SIRIH MERAH (Piper crocatum Ruiz and Pav.)

Abstract

The research was conducted at the cutting red bettle (Piper crocatum Ruiz and Pav.) to determined the effect of (1) the difference growth of cuttings of red bettle which are given IBA and without IBA, (2) the concentration of NAA on growth of cutting red bettle, (3) the concentration of NAA on growth of cutting red bettle on each given IBA. The treatment was arranged in factorial (2 x 4) in randomized block design with three replication. The first factor were without IBA (A) and the given of 1000 ppm IBA (A1). The second factor were the concentration of NAA consists of: 0 ppm (B), 1000 ppm (B1), 2000 ppm (B2), and 4000 ppm (B). The results showed that the NAA concentration of 4000 ppm produced the most number of roots on either at the node or at the base of cutting. Planting cutting red bettle which given IBA 1000 ppm was able to accelerated the time leaves open and increased the number of cutting which germinate. The mixtured of giving IBA 1000 ppm and the concentration of NAA 4000 ppm, produced the most number of cutting that germinated.

PENGARUH BERBAGAI JENIS AUKSIN DENGAN BEBERAPA KONSENTRASI TERHADAP PENGAKARAN SETEK MELADA (Piper colubrinum)

“…Pada tamanan stek lada varietas Natar 1 perlakuan campuran auksin NAA dan IBA dengan konsentrasi 6000 ppm adalah yang terbaik untuk merangsang pembentukan akar (Artha et al, 2015) pada Piper crocatum Ruizan Pav. konsentrasi NAA 4000 ppm + IBA 1000 ppm adalah yang terbaik untuk merangsang pembentukan akar (Maulida et al, 2014).…”

Induksi Somatic Embriogenesis dan Kultur Suspensi Sel Pada Tanaman Porang (Amorphophallus muelleri Blume)

“…Fase koleoptilar sel memanjang mengandung sitoplasma mulai muncul meristem apikal sehingga bagian ujung lebih runcing akan berkembang menjadi calon tunas karena akan muncul meristem perakaran. Hormon golongan auksin misalnya NAA dan 2,4-D memiliki peran untuk merangsang bagian sel, pembentukan kalus, pemanjangan tunas selain itu untuk merangsang pembetukan akar (Maulida et al, 2014).…”
