Physiological quality in seeds of the common bean is aff ected by the period of nutri-priming
- Nutri-priming is a low-cost and highly e ff ective way of supplying seeds with micronutrients. The aim of this study was to evaluate the physiological quality of seeds of the Pérola cultivar of the common bean under nutrient solutions containing molybdenum, cobalt and zinc for di ff erent imbibition times. The experiment was carried out in the laboratory and greenhouse of the State University of Goiás UEG – UnU Ipameri, using a completely randomised experimental design, with eight micronutrient treatments (T1. Control; T2. Mo; T3. Zn; T4. Co; T5. Mo + Co; T6. Mo + Zn; T7. Zn + Co; T8. Mo + Co + Zn) and six imbibition times (6, 8, 12, 16, 20 and 24 hours). The variables under analysis were seed imbibition, germination test, fi rst germination count, accelerated ageing, seedling emergence, emergence speed index, shoot length, root length, total length, fresh weight, dry weight, and shoot and root biomass. The micronutrients a ff orded an increase in germination in the seed batches under evaluation; on the other hand, imbibition times of greater than four hours reduced the germination capacity of the seeds. It can be concluded that nutri-priming in the common bean is only bene fi cial for an imbibition time of up to four hours.

期刊介绍: To publish technical-scientific articles and study cases (original projects) that are not submitted to other journals, involving new researches and technologies in fields related to Agrarian Sciences. Articles concerning routine analysis, preliminary studies, technical notes and those which merely report laboratorial analysis employing traditional methodology will not be accepted for publication. The Journal of Agronomical Science also has the mission to promote the exchange of experience in the referred fields.
