『壹』 英文前言翻译

翻译： 英语 » 中文
Chlorocholine chloride (2-chloroethyltrimethyl-ammonium chloride,CCC) is an anti-gibberellin growth retardant,its mechanism is based on the restraint of the gibberellin biosynthesis in plant tissues.It is well known that CCC inces changes in the growth rate of grasses and the morphogenesis of potato plants cultured in vitro (Aphalo et al.,1997;Bandara et al.,1998;Luoranen et al.,2002). Attention has been paid in recent years to chlorocholine chloride (CCC) used widely in agricultural instry,especially increase potato tuber yield and quality, prevent wheat lodge and cotton growth like mad (Cao et al.,1997; Yamamoto and Nakata,1997;Caldiz et al.,1998).However the effects improved potato yield by CCC are not incarnated adequately.
Many researchers have studied the effects of CCC on the different aspects of photosynthesis of potato,such as carbohydrate composition and activities of sucrose metabolising enzymes (Sharma et al.,1998; Sharma et al.,1998; Liu,et al.,2005).Leaves of high-yielding potato usually have high chlorophyll content and higher net photosynthetic rate and longer functional leaf period (Dyson et al.,1965;Geigenberger et al.,2004).CCC was found to decrease the growth of stems,leaves and stolons,but promotes tuberisation in potato (Kumar and Wareing,1974;Menzel,1980;Nemchenko et al.,1981; Hussain et al.,2006.).CCC also promote tuberisation in potato plants growing under non-incing long day conditions and completely reversed the inhibitory effect of high temperature on tuber proction (Pruski et al.,2001;Tekalign and Hammmes,2004).CCC treatment effectively increased tuber yield under different salinity levels (Silva et al.,2001).These effects of CCC were suggested to be the modification of the carbohydrate metabolism and the relation between source and sink of plants (Deng and Prange,1988).But the effects of CCC on photosynthesis of potato leaf and its photosynthetic proctivity were poorly understood (Jansen et al.,2001;Navrátil et al.,2007).Yet very few attention focused on the effects of CCC on transport and distribution of photoassimilates in potato.Therefore,it is important to study the effects of foliar spray of CCC on the photosynthetic characteristics of potato leaves, transport and distribution of 14C -photoassimilates in potato such as 14C-soluble sugar and 14C-starch with 14CO2 isotopic tracer technique.To our knowledge,these effects have not been systemically studied.
The goals of this study were 1) to study the effects of CCC on photosynthetic characteristics,2) to compare the photosynthatic capacity,especially transport and distribution of 14C -photoassimilates in potato such as 14C-soluble sugar and 14C-starch after treatments with CCC in potato plants, 3) to discuss the relationship between source and sink regulated by CCC, and 4) to provide a theoretical basis for CCC application in the high-yield and good-quality cultivation of potato.

矮壮素（ 2 - chloroethyltrimethyl氯化铵， CCC认证）是一种反赤霉素增长阻燃剂，其作用机制是基于约束的赤霉素合成的植物tissues.it是人所共知的中华基督教会诱导的变化，增长率草形态发生马铃薯植物细胞体外培养（ aphalo等人， 1997年; bandara等人， 1998年; luoranen等人， 2002年） 。注重在近年来矮壮素（ CCC ）的广泛使用在农业产业化，特别是增加马铃薯块茎产量和品质，防止小麦投诉和棉花生长的疯狂（曹等人， 1997年;山和中田英寿， 1997年; caldiz等人， 1998年） ，但效果改善，马铃薯产量由中华基督教会都没有充分体现。
