Abstract:
Leaflet area, stomatal frequency, stomatal number per leaflet and their size in seven Trombay Groundnut
varieties were compared in summer and rainy seasons. Among them were evs TAG-24 and Somnath, which
were already proved to have higher water use efficiency. In all evs leaflet area was reduced during summer.
In TAG-24, Somnath, TG-22 and TKG-19A, reduction of leaflet area was associated with increased
stomatal frequency and stomatal number on adaxial surface. However, no significant differences were
observed for stomatal length and breadth. Reduced leaflet area with corresponding increase in stomatal
frequency and number of stomata on adaxial surface appear to be related with water use efficiency in TAG-
24 and Somnath.
