Effect on root growth - Root growth compensates for the effects of above-ground stress events, like high temperature and low humidity, by supplying water and nutrients to the shoot under stress. Any injury to the roots due to the high air temperature may aggravate the stress effects. High day temperature reduces root growth, while high night temperature does not result in similar response. 

During the early stages of growth, the optimum shoot growth occurs at soil temperatures between 31 and 37° C, whereas optimum root growth occurs between 25 and 31° C. Root dry matter increases with increasing soil temperatures from 20 to 30° C. The effect of soil temperature on root growth is less understood. Effect on the time to first flower, peg and pod formation - Initiation of flowers and subsequent flower production (i.e. flower number per plant) play a vital role in the reproductive cycle as they determine the potential sink size and the duration of seed filling. However, actual sink size is often limited by environmental stresses. 

Variations in the duration from sowing to flower opening in groundnut are correlated to mean temperature and thermal time. Similar to germination and leaf production, genotypes also differ in their time to flowering in response to temperature. Warmer day and night temperatures hasten flower initiation. Once fertilization is complete, the fertilized ovary (gynophore) begins to elongate geotropically towards the soil within 5-7 days after flowers are fertilized. An intercalary meristem, which is most active just below the base of the ovarian cavity, is responsible for the rapid growth of the peg during the aerial and early subterranean phases of fruit development.

 

Peg initiation rate increases as temperature increases. In terms of thermal time, peg initiation occurs when the plants have accumulated 660° Cd (cumulative degree-days) above a base temperature of 10° C. The optimum air temperature for pod development is about 25-28° C and varies with the cultivar. High temperature delays time from flowering to peg formation and pod initiation. Effect on flower, peg and pod numbers - Flower production in groundnut is affected by temperature.

Continuous high temperature during later stages of vegetative development can decrease flower production due to its effect on branching and growth. Reduction in flower number can also occur if flowers drop due to abscission when plants are exposed to severe or stressful environments.
