Abstract

Dendrobium as ornamental plants that are used as cut flowers, potted plants, wreaths, garden ornament has a high economic value (due to the type, beauty, shape, texture, flower size, and rarity), has a broad market opportunities, sources of germplasm as mains to cross in order to get new varieties, and to cultivate them do not require large tracts of land. to get orchid production which is reached with good cultivation, one of them is by using fertilizers and growth regulators (PGR) to obtain growth and good flowering of orchids. This study was conducted to answer the following questions: (1) Which type of foliar fertilizer that can generate the best response to the growth and flowering of orchid Dendrobium, (2) how the effect of benzyladenine (BA) on the growth and flowering of orchid Dendrobium, (3) whether there is an interaction between foliar fertilizers and provision of benzyladenine (BA) to influence the growth and flowering of orchid Dendrobium. The research conducted in the greenhouse, Faculty of Agriculture, University of Lampung from January to June 2014. The experiments were carried out with a complete randomized block design with three replications. The treatments arranged in factorial (2x5). The first factor of 2 types of fertilizers, was (NPK 20-15-15) and (NPK 10-40-15). The second factor is the various concentrations of BA are: 0, 100, 200, 300, and 400 mg/l. based on data and discussion of experimental results that have been raised, it can be concluded as follows: Gandasil fertilizer (NPK 20-15-15) and Hyponex (NPK 10-40-15), had no effect on the growth and flowering of plants Dendrobium hybrids indicated by a variable percentage of plants to germinate, the number of new shoots, the height of new shoots, the increase of leaf pseudo stem diameter, and the percentage of flowering plants. Application of benzyladenine (BA) on the concentration of 100-400 mg / l, can stimulate flowering orchid hybrid Dendrobium, which is indicated by an increase in the percentage of flowering from 60.50 to 64.83%. Application of BA on the concentration of 100-400 mg / l had no effect on the percentage of ornamental plants whis have new sprout, and the number and the height of new shoots. There is no interaction between the two types of NPK (20-15-15 and 10-40-15), with concentrations of BA in influencing all observed variables.

Abstract

In order to support the needs of the national textile industry, the necessary raw materials of high quality cotton, high grain yield and widely adaptable. To achieve these objectives, it is necessary the introduction of new cotton crop accession so that the resources can be available breeding elders. Given the genetic diversity and varieties of national cotton production stagnant. The study was conducted with the aim of getting the results of evaluation of growth of cotton plants introduced in tropical environments. Based on the analysis of variance, character growth, plant height, number of branches and monopodial simpodial, and time of harvest showed significant differences in the level of 1%. While the character of days to flowering and boll opening age showed significant differences in the level of 5%. There was variation in plant height were heterogeneous due to genetic differences. Differences in flowering dates, age boll opening and harvesting with significant variation is caused by environmental influences. Anticipated environmental factors that have the most primary role is long irradiation, recorded some sensitivity to fotoperiodisitas accession. The results of the study recommend accession CRIS-664 and CRIS-342 as source code elders with early maturity, because it has a lifespan of flowering and harvesting age equal even faster than local cultivars.

Abstract

The study of vegetable oils fortified with crude extract of carotenoid pigments from tomatothat contains lycopene as dominant antioxidant compounds becomes an interesting researchto be done. The aim of this research is testing the stability of the pigment of tomatoesextracts in the vegetable oil treated on some temperature levels. Spectroscopy method isused to measure the respond of pigment stability in fortified vegetables oils which treated bytemperature from 250C to 700C. Before the measurement is done by a spectrophotometerwhich connected to the thermostat, as much as 1 mg of extract pigment of tomatoes in crystalform was weighed for per sampel, then dissolved into 10 ml palm oil, coconut oil, sunflowerseed oil, and canola oil separately. The results showed that the temperature treatment causesthe value of the optical absorption decreased, which means that the pigment moleculesexperienced instability. The amount of impairment of the optical absorption withtemperature treatment from 250C to 700C at a wavelength of 482 nm, respectively, are: palmoil (Abs = 0.201); coconut oil (Abs = 0.213), sunflower oil (Abs = 0.232); and canola oil(Abs = 0.260). Decreasing value of absorbance (Abs) also indicates the lycopenedegradation that formed the derivatives molecule of this pigment.Keywords: fortification, lycopene, vegetable oil, temperature, tomato
