Abstract:
Taking ‘American Dasusheng’ and ‘Hongkong Boli’ two scattered lettuce varieties as materials,three photoperiods(12 h,16 h,20 h) were set,the impact of different photoperiods on lettuce’s morphological index,quality and absorptive amount to ions were conducted.The results showed that the photoperiod extension could improve lettuce’s height,length and width of the seventh leaf,aboveground fresh weight,root fresh weight and shoot dry weight significantly；the extension of photoperiod could increase soluble sugar content and reduce nitrate content of lettuce significantly in which there was a negative correlation between soluble sugar content and nitrate content,and the change of protein content had no significance；the extension of photoperiod could result in the significant increase of absorptive amount of lettuce to nitrate ions,phosphate ions and potassium ions,and the increase of absorptive amount to ammonia ions was not significant.
