Description Pongamia (Pongamia pinnata (L) pier.) locally known as honge. It is indigenous to
India, belongs to family Leguminaceae and sub family Pappilionaceae.
In this study, 40 candidate plus trees were selected from 10 different agro climatic
zones of Karnataka to study the effect of provenance on seed quality, nursery mixture , pre
sowing treatments on seed quality and characterization in pongamia. Among different
candidate plus trees tested zone-3 (Bijapur) was found superior for seed quality and zone-5
(Bangalore) was found superior for seedling parameters.
Among different nursery mixtures tested black soil + black sand + vermicompost
found superior over other nursery mixtures for seed quality parameters.
Among hydro priming treatments seed soaking for 16 hours (H2) found superior for
seed quality and seedling parameters, among interaction seed soaking for 16 hours and seed
treated with 0.2 % Bavistin found superior for seed quality and seedling parameters.
Each of 38 SDS- PAGE electrophorograms obtained for different Pongamia candidate
plus trees contained (CPT’s) 3 – 17 bands and distinctly different bands 2, 3, 4, 5, 6, 8, 16, 17
were common in candidate plus trees 1-19 and bands 1, 3, 5, 6, 9, 14, 16, 17 were common in
candidate plus trees 20-38. It was interesting that bands 5, 6 were unique in CPT’s 3, 4, 10,
11, 12, 19, 20, 21, 22, 29 and 30, CPT’s 33 and 5 would be identified on the basis of absence
of bands 1, 2, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 and 17. On the other hand, bands 1, 2 were
missing in CPT’s 8, 27 and 32.
Among twenty candidate plus trees tested for catalase, peroxidase, phosphates and
amylase activity, maximum was noticed in CPT 31 (2428 units), CPT 23 (62.5 units) CPT 27
(12.9 mM) and CPT 20 (1.00mg) respectively.
