Seasonal variation in specific leaf area,epicuticular wax and pigments in 15 woody species from Northeastern Mexico during summer and winter

The present study has been undertaken on the variability in specific leaf area,epicuticular wax and pigment content of 15 native woody species in northeastern mexico. the species showed considerable variability in responses of these leaf traits. majority of the species showed a decline in specific leaf area and epicuticular wax content. with respect to pigments,only few species showed a decrease,but some species showed an increase in pigments (chlorophyll a,b and total chlorophyll (a+b)) showing mechanism of adaptation to winter season.however,in few species there was a decline in pigment contents showing susceptibility to winter. © 2017,pakistan botanical society. all rights reserved.
