Figure 5.

A spider plot of 16 selected JIP parameters form chlorophyll a fluorescence in pigeonpea young leaves (a), mature leaves (b), young pods (c), and mature pods (d) after 24 h of incubation in normal temperature (25°C) as control, and high temperature 45°C for 24 h (HT), asterisks showed significant differences at p < 0.05 by multiple comparison (Tukey’s 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.
