Abstract

Agarwood has a high economic value because they have many benefits that cause agarwood to be hunted to meet the increasing market demand and its presence in nature is decreasing due to unwise conventional retrieval systems.The research objectives were to study the effect and determine the best concentration of NAA and BAP in callus induction of agarwood (Aquilaria malaccensis Lamk.). This research was conducted in the Tissue Culture Laboratory, Faculty of Agriculture, Andalas University from October 2018 until January 2019. The leaves of Agarwood were used as explants. The method used was completely randomized design (CRD) with different combinations of NAA and BAP (1.5 + 0.5 ppm, 3.0 + 0.5 ppm, 1.5 + 1.0 ppm, and 3.0 + 1.0 ppm). Data were analyzed using the F test and continued with Duncan’s Multiple Range Test at a level of 5%. The results showed that there was the effects of combination of growth regulator substances NAA and BAP on callus induction of agarwood. The concentration of NAA 3.0 ppm + BAP 0.5 ppm was the best in inducing callus with the percentage of explants life and explants form callus with 100%. The color of callus obtained varies, yellow, brownish yellow and brown.

Abstract

The germination process is the key to plant phenology, which significantly influences the success of early plant growth. Some seeds have a dormancy, so the germination process is hampered or does not occur. However, dormancy-breaking treatments in plants have been widely reported, such as breaking the dormancy of sugar palm seeds through physical scarification. This research aims to determine the best scarification position to break the dormancy of sugar palm seeds. This research was carried out at the Seed Technology Laboratory, Faculty of Agriculture, Universitas Andalas from July to October 2023. The design was completely randomized with scarification in two position variations, the operculum (A1) and dorsal (A2) points, repeated thrice. The results showed that the position of seed scarification affected the emergence time of cotyledon petioles and coleoptiles, germination capacity, and seed moisture content. Scarification at the operculum point requires a dormancy break of 16 DAP (Days After Planting) compared to 29 DAP for the dorsal. Seed viability was good in seeds sacrificed at the operculum point, with a germination percentage of 81.94%. Keywords: dorsal, operculum, cotyledon petiole
