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 induces 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 industry,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-inducing long day conditions and completely reversed the inhibitory ......余下全文>>
