KAJIAN ETHYLENE TRIPLE RESPONSE TERHADAP KECAMBAH TIGA VARIETAS KACANG HIJAU ABSTRAK Pembudidayaan tanaman kacang hijau selalu terkendala dengan keadaan lahan yang terbatas. Tanaman kacang hijau di tanam dengan tumpang sari, sehingga mengakibatkan tanaman ini tumbuh dengan keadaan ternaungi. Naungan ini menyebabkan naiknya produksi etilen, sehingga menimbulkan triple response yang dapat mempengaruhi pertumbuhan dan perkembangan tanaman. Oleh karena itu hal ini menjadi alasan dilakukan penelitian ini dengan etilen pada tiga varietas kacang hijau yaitu VIMA I, Seriti dan Kutilang. Setelah dikecambahkan tujuan untuk menyeleksi varietas kacang hijau yang tahan dengan adanya peningkatan jumlah selama 5 hari, panjang kacang hijau varietas VIMA I yang diberi karbid (penghasil etilen) adalah yang tertinggi. Bengkokan varietas kacang hijau yang terendah adalah varietas VIMA I. Namun untuk diameter kecambah ketiga varietas tidak berbeda nilainya baik yang diberi karbid maupun yang tidak diberi karbid. Dari penelitian ini menunjukkan varietas VIMA I adalah tanaman yang tahan terhadap peningkatan etilen, sehingga varietas ini berpotensi untuk ditanam di naungan. Kata Kunci :Etilen, Triple Response, Kacang Hijau STUDY OF ETHYLENE TRIPLE RESPONSE ON SEEDLINGS OF THREE VARIETIES OF MUNGBEAN ABSTRACT Grow green beans are always constrained by the state of limited land. Thus the green bean crop planted with intercropping, resulting in these plants grow with shady circumstances. However, this shade causes increased production of ethylene, causing triple response which can affect plant growth and development. Therefore this is the reason of this research with the aim of selecting resistant varieties of green beans with the increased amount of ethylene on three varieties of green beans that VIMA I, Seriti and Kutilang. Once germinated for 5 days, the length of green beans varieties by VIMA I carbide (ethylene producer) is the highest. And bend varieties of green beans were the lowest observed varieties VIMA is I who have given carbide. But for the three varieties of sprouts diameter does not vary in value whether it is given or not given acetylene carbide. From this research shows VIMA I is a plant varieties that are resistant to an increase in ethylene, so that this variety has the potential to be planted in the shade.

Ethylene Signalling

Ethylene is the simplest unsaturated hydrocarbon, yet it has profound effects on plant growth and development, including many agriculturally important phenomena. Analysis of the mechanisms underlying ethylene biosynthesis and signalling have resulted in the elucidation of multistep mechanisms which at first glance appear simple, but in fact represent several levels of control to tightly regulate the level of production and response. Ethylene biosynthesis represents a two-step process that is regulated at both the transcriptional and post-translational levels, thus enabling plants to control the amount of ethylene produced with regard to promotion of responses such as climacteric flower senescence and fruit ripening. Ethylene production subsequently results in activation of the ethylene response, as ethylene accumulation will trigger the ethylene signalling pathway to activate ethylene-dependent transcription for promotion of the response and for resetting the pathway. A more detailed knowledge of the mechanisms underlying biosynthesis and the ethylene response will ultimately enable new approaches to be developed for control of the initiation and progression of ethylene-dependent developmental processes, many of which are of horticultural significance.

A concept of ratio of radiant to thermal energy (RRT) has been developed to deal with the interactive effect of light and temperature on plant growth and development. This study further confirms that RRT is a useful parameter for plant growth, development, and quality control. Based on greenhouse experiments conducted with 27 treatment combinations of temperature, light, and plant spacing, a model for poinsettia plant growth and development was constructed using the computer program STELLA II. Results from the model simulation with different levels of daily light integral, temperature, and plant spacing showed that the RRT significantly affects leaf unfolding rate when RRT is lower than 0.025 mol/degree-day per plant. Plant dry weight is highly correlated with RRT; it increases linearly as RRT increases.

Brassinolide (BL) represents brassinosteroids (BRs)—a group of phytohormones that are essential for plant growth and development. Brassinazole (Brz) is as a synthetic inhibitor of BRs’ biosynthesis. In the present study, the responses of Wolffia arrhiza to the treatment with BL, Brz, and the combination of BL with Brz were analyzed. The analysis of BRs and Brz was performed using LC-MS/MS. The photosynthetic pigments (chlorophylls, carotenes, and xanthophylls) levels were determined using HPLC, but protein and monosaccharides level using spectrophotometric methods. The obtained results indicated that BL and Brz influence W. arrhiza cultures in a concentration-dependent manner. The most stimulatory effects on the growth, level of BRs (BL, 24-epibrassinolide, 28-homobrassinolide, 28-norbrassinolide, catasterone, castasterone, 24-epicastasterone, typhasterol, and 6-deoxytyphasterol), and the content of pigments, protein, and monosaccharides, were observed in plants treated with 0.1 µM BL. Whereas the application of 1 µM and 10 µM Brz caused a significant decrease in duckweed weight and level of targeted compounds. Application of BL caused the mitigation of the Brz inhibitory effect and enhanced the BR level in duckweed treated with Brz. The level of BRs was reported for the first time in duckweed treated with BL and/or Brz.
