Freshness-keeping effect of pretreatment solution for the cut flowers of Eustoma russellianum Griessb
We researched the freshness-keeping effect of four kinds of inorganic salt of pretreatment solutions for cut flowers of Eustoma russellianum Griessb.The results of this experiment show that all pretreatment solutions can prolong the vase-holding time,increase the fresh weight and the diameter of flowers,accelerate blooming,inhibit loss of water,delay the decrease of the content of soluble sucrose,reduce the accumulation of malondialdehyde(MDA) and maintain the stability of membrane to a certain extent.The best ornamental quality was observed in the pretreatment solution:2% S(sucrose)+200 mg·L-1 Al2(SO4)3+50 mg·L-1 NaClO.
