Abstract

Tectona grandis is an annual woody plant that has high economic value in trade commodities. Tectona grandis were usually produced in a conventional way using seed. However, large quantities of seed production in a given time become limited because of an outer layer of a hard seed. The success of tissue cultures is influenced by some factors, among which nutrients composition and plant growth regulator balance as a media component. Plant growth regulator which is used as a media component of tissue culture is the cytokinin  and auksin. The aim of this research is to identify the concentration of kinetin and BAP (Benzyl Amino Purine) concentration is the best for Tectona grandis. The research was carried out for three months, from October to December 2019, located in The Biotechnology Laboratory of Agriculture, Faculty of Agriculture, Tadulako University, Palu. The research was utilizes completely randomized design, with 6 handling of BAP 1 mg, BAP 2 mg, BAP 3 mg, Kinetin 1 mg, Kinetin 2 mg dan Kinetin 3 mg. The result of observation shown giving handles BAP and Kinetin have a distinct effect on seedling Tectona grandis growth by in vitro. Besides the other treatment, kinetin 2 mg provides the best response that is emerge bud (5.1) of the day, the number of shoots (1.6) of shoots and the number of leaves (4) of sheets.Keywords: Tissue Culture, Tectona grandis, Kinetin

Abstract

Macadamia (Macadamia integrifolia) is one kind of tree that have highly prospects as a non forest timber product. Macadamia produce nut that has many benefits. Macadamia nut were widely used in the food industry such as cookies, ice cream, candy and chocolate blend. One of the obstacles to Macadamia were to the processing a quality seeds for the cultivication of plants has not unfulfilled, so it must be imported from Australia. That’s why we need to research how to establish Macadamia plantation in improving germination process by using environmentally friendly technology to save the time, energy, and materials. The purpose of this research was to know the effect of seed condition and scarification. The method used was a complete randomized design, with two factors to impacted seeds. First one is seeds condition that are unintact (K1),intact (K2), and cracked (K3). Second one is scarification with the handling S0 (without submersion), S1(submersion with cool water for 24 hours), and S2 (submersion for 24 hours and drying  for 3 hours). The result showed that the condition of seeds and scarification significantly effect gemination rate percentage (%), and germination  seeds (day), but no significantly effect on height seedling (cm) in Macadamia. The best interaction of condition and scarification obtained intact the seeds that submersed by cool water for 24 hours and drying for 3 hours.Keywords: Macadamia integrifolia, Seeds,  Scarification, Submersion.
