“…The osmotic potential of the solution regulates the amount of water uptake by the seeds, thus enabling the completion of the early phases of germination under controlled conditions. The duration of the priming treatment may range from less than 24 h (Guedes and Cantliffe 1980) to several weeks (Khan et al 1980). Several American studies have indicated that osmopriming beetroot seed in PEG improves the emergence rate, the final stand and total yield of beetroot crops (Khan et al 1983;Khan and Taylor 1986).…”

“…Dentre as técnicas que têm sido estudadas para esta fi nalidade destaca-se o condicionamento osmótico ou "priming" (Khan et al, 1978;Khan, 1992), que consiste na pré-embebição das sementes em soluções osmóticas ou em água, de modo a permitir a ocorrência das etapas metabólicas iniciais do processo de germinação, sem permitir a protrusão da raiz primária (Heydecker et al, 1975;Khan et al, 1978;Bradford, 1986).…”

“…A partir daí, as sementes iniciam a embebição de água normalmente, paralisando o processo assim que entram em equilíbrio com o potencial osmótico da solução. O potencial osmótico é ajustado de maneira a permitir a ocorrência de todos os processos preparatórios da germinação, mas impedir o alongamento celular e, conseqüentemente, a emergência da radícula, mesmo após semanas de contato entre as sementes e a solução osmótica (Heydecker et al, 1975;Khan et al, 1978).…”
