將採收後的綠蘆筍嫩莖用室溫的水、冷水和室溫的三種硝酸鹽溶液淋洒,然後基部浸泡,在不同時間下取出樣品,切成原來的長度後,測量各種處理的嫩莖長度、鮮重、乾重、纎維素含量和木質含量。冷溫處理會減低抽長,使一定長度嫩莖的乾重不至減少太多。同時纎維化和木質也被抑制。以10^(-1)M左右的硝酸鎂、硝酸鈣、硝酸鈉溶液處理,嫩莖的抽長被抑制得更多;纎維化和木質化也受到明顯的抑制。
The effects of salt solutions (magnesium nitrate, calcium nitrate and sodium nitrate) and low temperature storage on the elongation, weight, and fiber and lignin contents of post-harvested green asparagus spears were conducted. Results showed that cold treatment inhibited the elongation of green asparagus spears. Fiber formation and lignification were also decreased. Salt solution (approximate 10^(-1)M) treatments were more effective in the inhibition of elongation. Fiber formation and lignification were also inhibited to various degrees by salt solutions.
