Abstract
We have performed chemical proximate analysis and determined the carbohydrate profile of mature seeds ofLupinus albus, cv.Rio MaiorandLupinus mutabilis, cv.Potosiplants, either well watered (ww) or subjected to a water-stress period (imposed from the 15th to 35th day after anthesis). Protein content from lupin seeds was 450 and 320 g kg<sup>−1</sup> of seed on dry weight basis, for ww plants, respectively, ofL. albusandL. mutabilis. Water stress did not affect protein content. The oil content of ww plants was about 120 g kg<sup>−1</sup> of seed dry weight forL. albusand 180 g kg<sup>−1</sup> of seed dry weight forL. mutabilis. Water stress reduced those values of half. The sugar content was about 90 g kg<sup>−1</sup> forL. albusand 50 g kg<sup>−1</sup> of seed dry weight forL. mutabilis, in ww plants. Water stress led to an increase in sugar content to 200 and 130 g kg<sup>−1</sup> of seed dry weight, respectively, forL. albusandL. mutabilis. Theα-galactosides amounted to 70 % of the total sugars (raffinose being 30 % and stachyose, 40 %) and sucrose was about 20 % of the total sugars. Water stress increased total carbohydrates and increased the sucrose/α-galactoside ratio, although reducing raffinose content and increasing sucrose content
