Abstract:
Pumpkin varieties inbred line ‘112-2’ and ‘Jiujiangjiaoding’ were used as materials.At 2-4 true leaf-fully expanded periods，morphological indexes (leaf length，leaf width，leaf area，stem length test，stem width)，chlorophyll content，stomatal density and disease index were determined，and relationship of different pumpkin indexes and powdery mildew resistance was discussed.The results showed that at the 2-3 true leaf-fully expanded periods，some morphological indexes (leaf area，leaf length，leaf width) and disease index of inbred line ‘112-2’ were slightly lower than those of ‘Jiujiangjiaoding’，other morphological indexes (stem width and stem length) and stomatal density were higher than ‘Jiujiangjiaoding’，and no significant difference was found.Chlorophyll content of inbred line ‘112-2’ was significantly higher than ‘Jiujiangjiaoding’.While，there were significant difference in the morphological indexes (except for stem width)，chlorophyll content，stomatal density and disease index of two kinds of pumpkin materials at 4 true leaf-fully expanded period.At the 2-4 true leaf-fully expanded periods，pumpkin materials (inbred line ‘112-2’ and ‘Jiujiangjiaoding’) respectively existed a negative correlation with disease index and stomatal density，a significantly positive correlation with chlorophyll content；disease index showed a negative correlation with chlorophyll content or stomatal density.Therefore，the powdery mildew resistance of the inbred line ‘112-2’ was stronger than that of ‘Jiujiangjiaoding’，which might be positively correlated with the chlorophyll content and stomatal density.
