In the present study, seeds were evaluated for their influence at laboratory condition with dry dressing seed treatment, using inorganic and organic nanopowder that can maintain the seed quality in groundnut VRI 2. Fresh seeds of groundnut were treated with inorganic NPs of ZnO, Ag and TiO2 each @ 750, 1000 and 1250 mg kg-1 and organic nanopowder of CLP and FSP each @ 1, 2 and 3 g kg-1 and stored for 12 months under ambient condition and to assess their effects on physiological parameter of seeds and explore of volatile metabolites emitted from the aged seeds relate with seed quality. Seeds treated with inorganic NPs and organic nanopowders did not vary for seed germination analyzed immediately after treatment. However, after 12 months of storage, seeds treated with ZnO NPs @ 1000 mg kg-1 enhanced germination (77%) against the control (66%). In the case of organic nanopowders, seed treated with FSP@ 2g and CLP@ 3g kg-1 had higher germination (75 and 75%) compared to control (66%). Volatiles emitted from the seeds treated with NPs revealed that the number of compound emitted under aldehyde, ketone, acids, ether, ester and carboxyl groups was less (20) while the control had 36 compouds, expressing a negative correlation to the germination. The present investigation clearly demonstrated the effect of inorganic NPs of ZnO @ 1000 mg kg-1 and Ag @ 1250 mg kg-1 and the organic nanopowders of FSP @ 2g kg-1 of seeds in maintaining the quality.Keywords

In cultivation of medicinal trees, seed germination is a very important problem. Various seed enhancements are being adopted nowadays to improve seedling emergence. Among these seed enhancement, seed fortification is an efficient method for increasing of seed vigour and improvement of germination and seedling growth. The laboratory experiment was conducted at the Department of Seed Science and Technology, Tamil Nadu Agricultural University, Coimbatore. The present study was conducted for evaluation of ecofriendly seed treatment with three botanical fresh leaf extracts in two concentrations with the soaking durations of 3 and 6h in Bael (Aegle marmelos). The results revealed that soaking of seeds in one per cent moringa (Moringa oleifera) leaf extract for 6h adopting 1:1 seed to solution ratio enhanced the seedling quality characters of bael in germination room and it was followed by 0.5 per cent tamarind (Tamarindus indica) leaf extract. On evaluation of these treatments at polypot nursery upto three months also exposed the efficacy of these treatments in production elite seedlings.Keywords
