dc.description.abstract | Organogenesis melalui kalus diharapkan meningkatkan keragaman genetik
vanili melalui induksi keragaman somaklonal. Penelitian ini bertujuan mempelajari
pengaruh pemberian 2,4-D dan kinetin serta menentukan konsentrasi yang tepat
dalam menginduksi kalus dari ruas vanili var. Vania 1 secara in vitro.Penelitian
dilakukan dengan Rancangan Kelompok Lengkap Teracak (RKLT) faktorial
dengan dua faktor perlakuan. yaitu konsentrasi 2,4-D (0; 0,5; 1,0; 1,5 mg L-1
) dan
kinetin (0; 0,05; 0,1 mg L
-1
) yang diulang sebanyak 10 kali sehingga terdapat 120
satuan percobaan. Hasil penelitian menunjukan bahwa kombinasi 2,4-D dan
kinetin tidak berpengaruh signifikan terhadap persentase eksplan hidup dan
browning serta ukuran kalus, namun interaksi keduanya dan pengaruh tunggal 2,4-
D berpengaruh signifikan terhadap persentase eksplan berkalus. Kombinasi 2,4-D
1,5 mg L
-1
dan kinetin 0,05 mg L
-1 menghasilkan persentase eksplan berkalus
tertinggi sebesar 22,22%. Pemberian 2,4-D konsentrasi 1,5 mg L?¹ secara tunggal
menghasilkan persentase kalus tertinggi sebesar 14,36%, sementara pemberian
kinetin dengan konsentrasi 0,05 mg L?¹ menghasilkan waktu tercepat untuk
munculnya kalus yaitu 13,94 hari. Kalus dapat beregenerasi membentuk tunas pada
kombinasi 2,4-D 1 mg L-1
dan kinetin 0,05 mg L-1
. Kalus yang terbentuk memiliki
tekstur kompak dengan variasi warna dari pale yellow (p.Y) hingga moderate
orange yellow (M.OY). | |
dc.description.abstract | Organogenesis through callus formation is expected to enhance the genetic
diversity of vanilla through the induction of somaclonal variation. This study aimed
to examine the effects of 2,4-D and kinetin application and determine the optimal
concentrations for inducing callus from vanilla var. Vania 1 internode in vitro. The
experiment was conducted using a factorial Randomized Complete Block Design
(RCBD) with two factors: 2,4-D concentrations (0, 0.5, 1.0, 1.5 mg L?¹) and kinetin
concentrations (0, 0.05, 0.1 mg L?¹), replicated 10 times, resulting in 120
experimental units.The results showed that the combination of 2,4-D and kinetin
did not significantly affect explant survival percentage, browning, or callus size.
However, their interaction and the single effect of 2,4-D significantly influenced the
percentage of callus-forming explants. The combination of 2,4-D 1.5 mg L?¹ and
kinetin 0.05 mg L?¹ produced the highest percentage of callus-forming explants at
22.22%. The application of 2,4-D at a concentration of 1.5 mg L?¹ alone resulted in
the highest callus percentage at 14.36%, while kinetin at a concentration of 0.05
mg L?¹ produced the shortest time for callus initiation, at 13.94 days. Callus
regeneration into shoots was observed in the combination of 2,4-D 1 mg L?¹ and
kinetin 0.05 mg L?¹. The resulting callus exhibited a compact texture with color
variations ranging from pale yellow (p.Y) to moderate orange yellow (M.OY). | |
