Abstract

Variation in chemical contents of seed, and foliage in Albizia lebbek (L.) Benth. of different provenances.

Abstract

Protein, oil, carbohydrate and starch contents of seeds of 12 provenances of Albizia lebbek [A. lebbeck] collected from sites in north and south India (latitude 9-32°N., longitude 72-85°E., and rainfall 40-400 cm), varied significantly (P<0.05). Seed protein content was positively correlated (r=0.838, P<0.05), and carbohydrate and starch contents were negatively correlated (r=-0.755 and r=-0.623, respectively, P <0.05), with the latitude of the seed source. Significant variation of N, P, K, Ca and Mg in stems and leaves of 1- and 3-yr-old plants was also observed when the provenances were grown at Hisar (29°10′N., 75°46′E., altitude 215 m), an arid region in north India. In general, provenances from north India at 3 yr old had greater chemical and mineral contents than those from south India. Chlorophyll content was highly correlated with the latitude of the seed source at 1- and 3-yr-old (r=0.742 and r=0.659, P<0.05, respectively), while crude protein of foliage at 3 yr old was significantly correlated (r=0.673) with latitude. Dehradun, Jammu and Hisar provenances from the north had comparatively greater concentrations of N, P and K at 3 yr old than those from south India.
