Abstract

Micropropagation of Phalaenopsis Orchid Using Explants of Flower Stalk. This studyaimed to obtain optimum media formulations for bud multiplication of micropropagation ofPhalaenopsis orchid using flower stalk. This study employed Completely Randomized Designwith 5 different treatments, i.e. M0 = MS + 150 ml/l coconut water + 2 g activated charcoal,M1 = MS + 1 ppm IBA+ 1 ppm BAP + 150 ml/l coconut water + 2 g/l activated charcoal M2= MS + 1ppm IBA+ 2 ppm BAP+ 150 ml/l coconut water + 2 g/l activated charcoal, M3 =MS + 1 ppm IBA+ 3 ppm BAP + 150 ml/l coconut water + 2 g/l activated charcoal, M4 = MS+ 1 ppm IBA+ 4 ppm BAP + 15 0ml/l coconut water + 2 g/l activated charcoal. Eachtreatment consists of 5 replicates, so there were 25 units experiment, with 3 explants each.Results of this study revealed that M2 media exhibited the best growth, as shown by swellingbuds (23.77 Days After Planting/DAP), earliest buds formation (49.33 DAP) and height ofbuds of 2,12cm.

Abstract

The Effects of Ecology, Growth and Yield Component to The Production of Grape:Multivariate Analysis Approach of SEM-PLS. The effects of the two main componentnamely ecological environment and genetic cannot be avoided during the process of growth ofplant since the early growth until it has produce yield. Ecological environment consist of soil,climate, and treatment mean while genetic mean variety of the plant. This research wasdesigned to study the effects of ecology, vegetative and gerative growth, and yield componento the production of grape. Structural Equation Modeling variance base with PLS Smart 2.0M3 was use to analysed the data. The result show that three of the four component hadsignificant effects on the production of grape, namely ecology, vegetative growth and yieldcomponens (p<0.05) mean while only generative component not has significant effects (tstatistic0.521 < 1.96). The production equation was PRODUCTION = - 0,235 KEKO + 0,243KVEGE + 0,020 KGENE + 0,417 KKHS (R2 = 63,2%).
