Abstract

Puar tenangau is a herbal plant of Zingeberaceae that from Thailand. The Plant has a big potential as pharmacy and traditional medicines, but the spread of this plant was unknown well in Indonesia even so needed a conservation for this plant. In vitro conservation is a one of alternative. In in vitro method, adding plant growth regulator is needed like Auxine and cytokinine.  Napthtalen-3-Acetid is kind of auxine that good to root growth and Benzil amino purin is kind of cytokinin to shoot growth. The research aimed to know the influence of Benzylamino purine (BAP) and Napthtalen-3-acetid acid (NAA) concentration on the growth of puar tenangau.The research was carried out in the Tissue Culture Laboratory, Agriculture’s Faculty of Nort Sumatera University from March to June 2012. This research used Completely Randomized Design with two factors. First factor was BAP concentration consist of four levels:0 mg/l; 2 mg/l; 4 mg/l; 6 mg/l. The second factor was NAA concentration consist of three levels are 0 mg/l; 1.5 mg/l; 3 mg/l. The results showed that BAP concentration give effect significantly only on leaves number in 12 weeks after planting, but it have no effect significantly on the percent of living explant, plantlet height, leaves number on 4 and 8 weeks after planting. NAA and interaction of BAP and NAA have no effect significantly to living explant, plantlet height, leaves number on 4,8 and 12 weeks after planting.   Keywords: puar tenangau, BAP,NAA, In vitro.

Abstract

The effect of giberellin on growt of sugar palm in nursery (Arenga pinnata Merr). Application of giberellin were done to know effect on the growth of sugar palm seed. The research  used randomized block design with 5 levels of  0 ppm, 50 ppm, 100 ppm, 150 ppm, and 200 ppm. The parameters observed were seed height, leaf sum, leaf chlorophyl, steam diametre, wide leaf, fresh weight of crown, fresh weight of root, dry weight of crown and dry weight of root. The result of research showed that effect of giberellin  significantly on  seed height 10, 12, 14 weeks after planting and the optimum concentrate was on 200 ppm and not significantly number of leaf, chlorofil content, steam diametre, wide leaf, fresh weight of shoot, fresh weight of root, dry weight of shoot and dry weight of root.   Keywords : sugar palm, giberellin, growth.
