A qualitative study of the nodulating ability of legumes of Pakistan-list 6

摘要

Nodulation was studied in 31 species belonging to 24 genera distributed in 18 tribes of subfamilies Caesalpinioideae, Mimosoideae and Papilionoideae from Balochistan. Of these Caesalpinia gilliesii (Hook) Dietr., Delonix regia (Bojer) Rafin., Cercis siliquastrum Linn., and Ebenus stellata Boiss., were found as non-nodulators whereas Senna holosericea of Caesalpinioideae, Caragana ambigua and Onobrychis dealbata of Papilionoideae have been reported as nodulators for the first time. The nodulation status of Ebenus stellata as non-nodulator is also being reported for the first time. Nodule colour, shape and frequency of the nodulated species is described.
