Abstract
The rate/temp. relation of several developmental processes in groundnuts was examined in greenhouses maintained at mean air temp. of 19, 22, 25, 28 or 31°C. The sensitivity of the processes to soil water deficit was also examined by applying 30 mm of irrigation immediately after sowing and when tensiometer readings at 0.1 m depth exceeded 20 kPa. (wet soil treatment) to half of each house, the other half being the dry soil treatment. When the relation between rate and temp. was linear, measurements were analysed in terms of thermal time and an extrapolated base temp. (Tb) at which the rate was zero. Tb was c. 10°C for leaf appearance, branching, flowering, pegging and podding. A higher value of Tb for seedling emergence (16°) was probably an artifact caused by soil pathogens. Leaf appearance and branching were more sensitive to soil water deficit than the other processes examined
