Studies on maturity indicators of Leucaena leucocephala in northern India

Leucaena leucocephala is a medium-sized, multipurpose tree which is a valuable source of pulpwood, small timber, fuel wood, fodder and green manure. Poor and delayed seed germination is reported due to seed collection at improper maturity stage coupled with physical dormancy. Hence, the present study was carried out to determine the exact maturity stage for seed collection at three locations of northern India i.e. Agra (S1), Mathura (S2) and Hathrus (S3). Among the different pod/seed collection periods, 1 st week of June (8th collection)was found best across all the sites as maximum germination 58.7+0.25% at S1, 55.1+0.43% at S2, 54.2+0.28% at S3 was recorded during this stage. The results revealed that moisture content decreased with advancement of maturity. The brown colour of pod and dark brown colour of seed were identified as seed maturity indicators. | Studies on maturity indicators of Leucaena leucocephala in northern India
