Abstract
At two distinctive habitats, the chlorophyll contents (Chl.), its thermostability (CSI) and some metabolic substances in four shrubs were studied. The obtained results revealed that, the Chl. content, Chl. a/b ratio and CSI were variables among the investigated species in response to seasonality, habitat, species and their interactions. Generally, the low Chl. contents were accompanied by an increased in CSI. Statistically, the single factors and their interactions had significant effects on the investigated constituents of plants with some exceptions. It was found that, the seasonality was greatly affected the Chlb, Chl. a/b ratio and total chlorophyll. The species factor had a major role on the Chla and CSI. The same was true in case of the rest constituents in plant tissues, whereas the habitat factor had a dominant role on Mg+2. The results showed that the C. procera was the highest in chlorophyll stability to heat and the lowest in the amount of chlorophyll, and vice versa was in the O. europaea plant. The correlations between CSI and free amino acids were significantly positive. Also, the Chl. contents were positively correlated with soluble sugars. Within species, the specific correlations between different chlorophyll parameters and other components in plant tissues were discussed.
