 ABSTRACT

The present study was carried out in the Department of Seed Science and Technology Section, CCS Haryana Agricultural University, Hisar, India. The study evaluated the effect of seed invigoration treatments on seed performance under field condition of American cotton varieties (H-1098(I), H- 1117 and H-1236) which were picked at different intervals and stored at 20oC with six per cent moisture content in sealed plastic containers. Study evaluated the effect of different seed priming treatments on Electrical conductivity, mean emergence time, Field emergence index and seedling establishment of cotton varieties to determine and exploit their usefulness in improving cotton seed quality for better seedling establishment. Seed ageing or progress in storage period led to reduction in seed quality, during storage as there is reduction in seed vigor potential and performance, stand establishment, poor emergence and high seedling mortality, thus leading to poor crop stand. Study reveals that improvement in field performance by seed priming may combat this problem as this physiological technique results in faster and synchronous seed germination as found in the study that when cotton seeds were primed for two hr. at 25o C with different chemicals (Control, KH2PO4, KNO3, PEG, GA3, Hydration- Dehydration) showed increase in seedling establishment. It was found that seeds primed with      GA3 significantly enhances the field performance in terms of mean emergence time, field emergence index, seedling establishment and lower electrical conductivity Maximum performance was observed in seeds of second pick seeds with priming treatment whereas minimum was observed in third pick seeds.

Key words: Gossypium, Electrical conductivity, Mean emergence time, Field emergence index and seedling establishment
