Pengaruh Pemberian Auksin dan Giberelin terhadap Pertumbuhan Vegetatif Tanaman Bawang Putih Lokal Timor (Allium sativum L.)

Abstract

Local Timor garlic has more distinctive taste and aroma and is used as a flavoring and as a medicinal ingredient for people on the island of Timor, especially in Nort Central Timor Regency, but a production has decreased since 2015. Therefore, an efforts to increase production are needed, one of which is by using auxin and gibberellin. This research aims to determine the effect of auxin and gibberellin on the vegetative growth of local Timor garlic. The study used a Completely Randomized Design with 7 treatments, namely P1 (no treatment), P2 (Auxin 50 ppm), P3 (Auxin 100 ppm), P4 (Auxin 150 ppm), P5 (Gibberellin 50 ppm), P6 (Gibberellin 100 ppm), and P7 (Gibberellin 150 ppm). The results showed that the addition of auxin and gibberellin had a significant effect on plant height, especially at 15, 45 and 60 days after planting, but had no significant effect on the number of leaves and stem diameter.
