  4. Rubber tree ( hevea brasiliensis ) is an important economic woody - crop in tropical areas. its latex is the unique source of crude rubber used in current industry. because of its special and important use, the rubber tree has been extensively planted in tropical areas. increase production is always the main target in rubber tree cultivation. since the ethrel was applied in increasing latex production in 1968 for the first time as a chemical stimulant, not only the latex production had been increased largely, but also a new set of rubber tapping system had been established, leading to a series of economic benefit. owing to ethrel " s extensive application, its side effects had been found more and more obviously, such as tapping dry, speeding up senescence, shortening the life span of rubber tree etc. in order to overcome the side effects and increase production more availably, for a long time, people had carried out lots of research work on cell level, membrane level, physiology and biochemistry of laticifer contents. but the mech anism why ethrel increased latex production was not yet understood completely. this study had cloned the ethylene receptor gene ( efrl ) from rubber tree, and researched the relationship between etrl expression in laticifers and ethrel stimulation on transcription level and protein translation level. the results were as follows : 1

    但是，由於乙烯利應用的普及，乙烯利刺激割膠引起橡膠樹發生死皮病及加速膠樹衰老，縮短膠樹壽命等副作用也越來越明顯。為了克服這些副作用，使乙烯利能更有效地刺激增產，長期以來，人們在細胞水平、膜水平和乳管細胞內含物的生理生化層面上進行了大量的研究，但仍未完全了解乙烯對膠樹的作用機制。本研究從分子水平入手，克隆橡膠樹的乙烯受體基因（ etr1 ） ，並在轉錄水平和蛋白質翻譯水平上研究etr1基因在乳管細胞中的表達及與乙烯刺激的關系，取得了以下結果： 1
  5.
