Abstract

Cabe jawa merupakan tanaman obat dan rempah yang penting dalam industri obat di Indonesia. Cabe jawa diperbanyak dengan cara stek sulur, namun kendala yang dihadapi dalam penanaman adalah mudah layu dan lambat pertumbuhannya. Penggunaan jenis sulur dan konsentrasi zat pengatur tumbuh (Rootone F) merupakan salah satu upaya untuk mempercepat pertumbuhan stek tanaman. Penelitian ini bertujuan untuk mengetahui respon pertumbuhan tiga jenis sulur cabe jawa terhadap pemberian berbagai konsentrasi Rootone F. Penelitian menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan dua faktor. Faktor pertama adalah konsentrasi Rootone F yang terdiri dari 4 taraf yaitu 0 mg/liter, 100 mg/liter, 200 mg/liter, 300 mg/liter, dan faktor kedua adalah jenis sulur yang terdiri dari 3 taraf yaitu sulur tanah, sulur panjat, dan sulur produktif. Hasil penelitian menunjukkan adanya interaksi antara jenis sulur dan konsentrasi Rootone F pada variabel jumlah tunas. Konsentrasi Rootone F tidak berpengaruh nyata terhadap semua variabel pengamatan. Sulur tanah merupakan jenis sulur terbaik dalam pertumbuhan stek cabe jawa.

Abstract

[GROWTH OF DRAGON FRUIT (Hylocereus constaricensis) STEM CUTTINGS AS AFFECTED BY CONCENTRATIONS AND DIPPING TIMES OF COCONUT WATER]. Dragon fruits (Hylocereus constaricensis) is commonly propagated vegetatively by using stem cutting. In this respect the use of natural plant growth regulator, such as coconut water, to promote the growth of the cuttings is very important. The objectives of this experiment were to evaluate water coconut concentration, dipping time of stem cutting in the coconut water, and the combination of both to promote the growth of dragon fruit cuttings. The experiment was arranged in Randomized Complete Block Design (2 factors, 5 replications). The first factor was the concentration of coconut water, consisting of 5 levels: 20, 40, 60, 80, and 100%. The second factor was dipping time of cutting in the coconut water, consisting of 4 levels: 2, 4, 6, and 8 minutes. The results showed that the increasing coconut water concentration had increased the shoot growth in a liner fashion. A similar trend was also observed for coconut water dipping time. The highest shoot growth was found on 60 % coconut water.

Abstract

[GROWTH AND YIELD OF F4 SWAMP RICE LINES ON LINE SWAMP]. Growth and yield of swamp rice are depending on the plant ability to adapt in swampy agro-ecosystem which characterized by several limiting factors. This study was addressed to evaluate the growth and yield characteristics of six lines of swamp rice bred for the development of high-yielding rice varieties best suited for swamp land production. Evaluation was conducted in a pot experiment using UBPR2, UBPR3,UBPR6, UBPR7, UBPR9, and UBPR10 as planting materials. These lines were the F4 generation derived from crosses involving local Bengkulu swamp rice varieties. Observations were made on 13 plant characteristics, dry matter accumulation,  leaf area ratio, specific leaf weight, net assimilation rate, plant height, productive tiller number, heading date, maturity date, panicle length, grain number per panicle, percent of filled grain, and plant yield (the grain weight per clump).  The collected data were subjected to analysis of variance and least significant difference test at 5% level.  Results indicated that all lines physiologically exhibited similar growth patterns, excepting the capability of accumulating dry matter at 40 dap. In this case, UBPR6 produced the highest dry matter accumulation (24.34 g). Based on the morphological performances, significant variations among the lines were observed on most of the observed characteristics, except on productive tiller number and panicle length UBPR10 was the line produced the tallest plant stature (160.72 cm), UBPR2 was the earliest flowering and maturing line (76,33 and 111 dap), whereas UBPR6 was the line produced the highest grain number per panicle (212,2), percent of filled grain (95%),  and plant yield (82.50 g per clump).

Abstract

[STIMULATION EFFECTS OF BIOURINE CONCENTRATION AND THE STEM SEGMENT OF CUTTINGS ON  GROWTH OF TEA (Camellia sinensis) SEEDLINGS]. Tea seedlings can be prepared by the stem segment cutting and provide treatment to stimulate the growth of cuttings. This study aims to determine the optimal tea seedlings growth from different material of stem segment and biourine concentration. The experiment was conducted in February to June 2020 at PT. Sarana Mandiri Mukti Kelurahan Tangsi Baru, Kabawetan District, Kepahiang Regency, Bengkulu Province. This research uses factorial completely randomized design (CRD) with two factors. The first factor, biourine concentration consisting of 5 levels including 0%, 25%, 50%, 75%, 100%. The second factor, the stem segment of cuttings consisting of 3, 4, and 5 segments. The treatment was repeated 3 times, with 5 plants sample in each treatment. There was totally  225 plants. The results showed that biourine concentration of 100% has significantly different from the variable roots number and root length. The stem segment of the tea cuttings has no significantly difference  effect on all variables. The interaction between biourine concentration and stem segment of the tea cuttings has significantly different in variables of shoot length and seedlings fresh weight. The optimum growth of tea seedling was obtained in stem cutting of 3 segment and application of biourine concentration of 100%.
