Megjegyzések:	We still lack knowledge concerning the mode of action of engineered nanoparticles in agriculture. The key point of this study is to investigate the role of nano-silica (NS) to enhance the seed germination and growth development of common bean. Four different concentrations of NS suspensions (100, 200, 300, and 400 mg L-1) were supplemented to nursery and growth media. Our results showed that 300 mg L-1 of NS increased the final germination percentage from 82.3 to 97.7%, the germination speed from 24.9 to 36.2% / day, the vigour index from 14.3 to 20.2, and decreased the mean germination time from 4.3 to 3.3 days. Strikingly, 300 mg L-1 of NS increased the root dry mass of common bean seedlings by 93.5%,the shoot dry mass by 78.7%, the root length by 32.7%, and the shoot length by 13.2% versus untreated seedlings.This study proved that NS is able to improve the germination and growth of common bean as a result for altering some physiochemical reactions after penetrating the seed coat.

Cím:	Engineered silica nanoparticles alleviate the detrimental effects of Na+ stress on germination and growth of common bean (Phaseolus vulgaris) / Abdullah H. Alsaeedi, Hassan El-Ramady, Tarek Alshaal, Mohamed El-Garawani, Nevien Elhawat, Mahdi Almohsen

Megjegyzések:	During the past 10 years, exploiting engineered nanoparticles in agricultural sector has been rapidly increased. Nanoparticles are used to increase the productivity of different crops particularly under biotic and abiotic stresses. This study aims to test the ability of nanosilica (NS) to ameliorate the detrimental impact of Na+ with different concentrations on the seed germination and the growth of common bean seedlings. Five doses of Na+ have been prepared from NaCl, i.e., 1000, 2000, 3000, 4000, and 5000 mg L-1, and distilled water was applied as a control. Seeds and seedlings were treated with three different NS concentrations (100, 200, and 300 mg L-1). The results proved that Na+ concentrations had detrimental effects on all measured parameters. However, treating seeds and seedlings with NS improved their growth and resulted in higher values for all measurements. For instance, the addition of 300 mg L-1 NS leads to an increase of the final germination percentage,vigor index, and germination speed for seeds irrigated with 5000 mg Na+ L-1 by 19.7, 80.7, and 22.6%, respectively. Although common bean seedlings could not grow at the highest level of Na+, fortification seedlings with NS helped them to grow well under 5000 mg L-1 of Na+. An increase of 11.1 and 23.1% has been measured for shoot and root lengths after treating seedlings with 300 mg L-1 NS under irrigation with 5000 mg Na+ L-1 solutions, and also at the same treatment, shoot and root dry masses are enhanced by 110.9 and 328.0%, respectively. These results proved the importance of using NS to relieve the detrimental effects of Na+-derived salinity. This finding could be reinforced by low Na content which was measured in plant tissues after treating seedlings with 300 mg L-1 of NS.
