Effect of silicon dioxide and nano silicon dioxide on seed germination indices of Cucurbita pepo

The pumpkin belongs to the family Cucurbitaceae. The bush is a one-year-old plant with fleshy fruits and usually oval seeds [۱-۲]. In order to investigate the effect of silicon dioxide and nano silicon dioxide on experimental pumpkin germination in a completely randomized design with three-dose silicon dioxide treatments (۱۰, ۳۰ and ۶۰ mg / L) and nano silicon dioxide Three levels (۱۰, ۶۰۰ and ۶۰ mg/L) were performed in ۳ replications in ۲۰۲۰. The studied traits were: germination percentage, germination rate, germination index, seed vigor index, bud length, bud diameter, fresh weight, dry weight and number of buds. The results showed that treatments had significant effect on germination percentage, germination rate, germination index, seed vigor index and number of buds at ۱% probability level but not on germination length, bud diameter, fresh weight and dry weight. The highest germination percentage, germination rate, germination index, seed vigor index and number of buds were observed in silica treatment at concentrations of ۱۰ and ۳۰ mg / L. According to the results of this experiment, application of silicon dioxide on pumpkin seeds can provide faster germination and stronger seedlings.
