| Title : | INFLUENCE OF STORAGE TIME ON QUALITY OF ENCRUSTED MAIZE SEEDS |
| Abstract : | The field germination of maize seeds is significantly affected by high soil moisture and suboptimal temperature, under adverse conditions it can decrease to 39%. Pre-sowing treatment of seeds by encrusting them with a conjugate based on biodegradable polymers and containing bioregulators increases the resistance of seeds to unfavourable conditions and promotes uniform germination and growth. The purpose of this study was to determine the changes in germination capacity, vigour and metabolic efficiency of encrusted maize seeds during 12 month of storage. The bioconjugate used for encrustation is based on sodium salt of carboxymethylcellulose containing genistifoliosides (iridoid glycosides extracted from Linaria genistifolia) as growth bioregulator. Seeds of P427 and P458 hybrids were encrusted and stored under laboratory condition. Their quality was compared with maize seeds of the same hybrids, commercially encrusted. Both vigour I and vigour II of P458 hybrid seeds were 1.15-1.54 and 1.28-1.94 times higher than those of P427 hybrid seeds, respectively. This regularity also persisted in seeds encrusted with the bioconjugate during the entire period of the investigation. High negative correlations between the biomass eliminated for respiration and the metabolic efficiency were revealed; the correlation coefficients were - 0.9557 (P427) and - 0.9457 (P458). The initial metabolic efficiency of seeds encrusted with the bioconjugate was reduced compared with intact seeds, but upon storage, it became higher than metabolic efficiency of intact seeds and commercially encrusted seeds. Thus, the encrustation with an environmentally friendly bioconjugate preserved the sowing qualities of maize seeds for a long storage time. |
