Abstract
Three types of hydrangea,Hydrangea areborescense'Annabelle'(A),Hydrangea paniculata'Vanilla Strawberry'(B),and Hy-drangea macrophylla'Endless Summer'(C)were used as experimental materials,during the natural cooling process in the open field of Bei-jing,the differences in cold tolerance of Hydrangea were studied by measuring the survival rate of the following year,the relative conductance of leaves,soluble sugar,soluble protein,and relative water content under three cold resistant covering conditions.The results showed that dur-ing the natural cooling process,overwintering survival rate,soluble sugar and soluble protein content in leaves were ranked with C>A>B,the relative conductance of leaves was ranked with C>A>B,relative water content ranked with C>B>A.The conductance of the three types of Hy-drangea increased with the decrease of temperature;there was a partial correlation between soluble sugar,soluble protein,and relative water content and temperature changes.The comprehensive evaluation results showed that almost all three types of Hydrangea could achieve outdoor overwintering in the Beijing area,but there were certain differences in cold resistance.The cold resistance was ranked with'Endless Summer''Annabelle'and'Vanilla Strawberry'.The use of covering could have a certain cold resistance effect.关键词
