Lipid composition of peanut seeds (Arachis hypogaea L.) obtained under different situations of water availability.

The changes in the lipid composition, oleic/linoleic ratio (O/L) and iodine value (IY) for Florman INTA peanut seeds of different sizes obtained under two different water availability conditions during reproductive period wer e, evaluated. The water availability affected O/L ratio, IY, and the content of all fatty acid but behenic. The seed size affect the oleic, eicosenic and behenic co ntents. Interaction between water availability and size seed in relation to lipid and lignoseric acid content were also detected. The greatest water availability produced seeds with more lipid content. Mor eover, probably due to an indirect effect of less soil temperature, the ins aturated lipid concentration was increased as can be seen in the less O/L r atio and augmented IY.
