Pertumbuhan Tunas Sansevieria trifaciata Prain ‘Laurentii’ pada Beberapa Komposisi Media Tanam dan Konsentrasi GA3

Abstract

<p style="text-align: justify;">The objectives of this research was to know the effect of growing media composition and concentration level of GA3, on growth of Sansevieria trifaciata Prain ‘Laurentii’ shoots. The research was conducted at Leuwikopo Experiment Field, IPB, Darmaga from March until July 2011. The research used Randomized Complete Block Design (RCBD) with two factors and three replications, Sansevieria trifaciata Prain ‘Laurentii’ variegata leafs used in this research. The first factor was growing medium composition, they were charcoal husk:soil:compos (1:2:1); pasir malang:soil:compos (2:2:1); cocopeat:soil:compos (3:2:1). The second factor was concentration of GA3 treatment consist of three level, 0 ppm; 100 ppm; 500 ppm. Charcoal husk and pasir malang gave good effect for growth of young shoots. Concentration of GA3 until 500 ppm had no significant effect on young shoot growth but it had significant effect on roots growth. The best interaction treatment effect on young shoots growth was charcoal husk medium and 500 ppm concentration of GA3.</p><p>Keywords: charcoal husk, cocopeat, leaf cutting, pasir malang</p>

Dissolving Pulp from Sansevieria Trifasciata Fiber Processed with Water-Pre-Hydrolysis, Soda-Anthraquinone Cooking and Clorine Free Bleaching<i> </i>

“…Comparing it to SB (57.3%) and Acacia mangium (52.1%) reveals no appreciable differences. The main benefit of ST as a potential resource for DP production in Indonesia is that this tropical plant is simple to grow and survives in a wide range of temperatures and light provided by its significantly more abundant stock than other plants, which have been estimated to be harvested only every 3-4 months [21,22,23].…”

Pemantauan Penyerapan Gas Beracun Menggunakan Tanaman Sansevieria Pada Ruangan Tertutup

“…Sansevieria trifasciata atau lidah mertua merupakan tanaman hias yang sering dijumpai dipinggir jalan, di taman, dan di perkarangan atau ditanam dalam pot sebagai penghias ruangan [7]. Lidah mertua mampu memberikan udara bersih bagi ruangan yang ditempatinya karena tanaman ini dapat menyerap zat berbahaya di udara [8], [9].…”

Effects of Planting Medium on the Propagation of Loquat (Eriobotrya japonica L.) from Cuttings and Seeds

“…Roasted rice husk has good aeration that can improve the physical and chemical structure of the soil, and the process of burning rice husk will produce a sterile medium that can protect plants from plant growth-disturbing pathogens (Gustia 2013). Suharsi and Andriani (2013) stated that the composition of roasted rice husk, soil, and compost of 2:2:1 is the best medium to stimulate Sansevieria leaf shoot cuttings.…”
