Figure 2.

Tissue specific photosynthetic pigments of pigeonpea under normal temperature (I, D) and elevated temperature (heat stress) (IHT and DHT): Chlorophyll a (a), chlorophyll b (b), total chlorophyll (c) and carotenoids (d) contents in different stages of leaf and pod. Each value is the mean of replicates (n = 10) with standard error of mean in percentage with 5% value. Significant differences at p < 0.05 are indicated by asterisks (student t-test).

Abbreviation: I: irradiance; D: darkness; IHT: high temperature under irradiance; DHT: high temperature under darkness; YL: young leaves; ML: mature leaves; YP: young pods and MP: mature pods
