Germination of Punica granatum seed according to temperature and storage period

Abstract: The aim of the study was to evaluate the germination of P. granatum seeds after storage under different temperatures. The experiment was performed at Universidade Tecnológica Federal do Paraná -UTFPR -Campus Dois Vizinhos. The seeds were stored in sealed glass jars under temperatures of 5°C, 10°C e 25°C, por 0, 30, 60, 90, 120, 150, 180, 210 and 240 days. After each period, the seeds were sowed in Gerbox ® boxes kept at 25°C. A completely randomized design was used, in a factorial 3 x 9 (temperature x period o… Show more

“…The lower 1000SW recorded with plants developed from 8% MC could be due to reduced plant growth and resources utilization associated with imbibitional damage (of seeds with cracks in the seed coat) and slow membrane repair. The period of membrane repairs is shorter for seeds with high moisture content than those of low moisture content [26]. The variation observed could also be due to the influence of the factors in preserving seed nutrient reserve in storage to produce vigorous seedlings on the field leading to good seed filling [27][28][29][30].…”

“…Accordingly, seeds stored at -10°C had the highest germination capacity in all storage months compared to the two storage temperatures. Many authors also reported that low temperature and low relative humidity are required to maintain the quality of the seeds (Schwallier et al 2011;Silva et al 2019). also reported that the storage environment influences the response of seed storage behavior.…”

“…Hence, proper seed storage minimizes the rate of deterioration and the loss of viability (Singh et al 2017). Environmental storage conditions such as temperature and seed water content are the most relevant factors for conserving seed viability (Silva et al 2019). The impact of moisture content and temperature on seed quality is, therefore, of particular significance in tropical countries where ambient conditions tend to lead to a rapid loss in seed quality (Singh et al 2017;Ibraheem et al 2021).…”
