| Abstract: | The morphology and partial physiological indexes of Salvia splends,Zebrina pendula and Chlorophytum comosum were studied after 24 h exposure of formaldehyde gas(0,40,80 and 120 mg/m3)in a closed chamber.The results showed that: S.splends was injured firstly,whose leaves appeared coke side;the leaves of Z.pendula wilt at 80 mg/m3 content;but C.comosum had no significant changes with the increasing of formaldehyde content.The contents of MDA and soluble sugar,relative conductivity,chlorophyll content showed a... |
