Abstract
This research was conducted under laboratory conditions at the Faculty of Natural and
Life Sciences, University of Hamma Lakhdar - El-Oued during the academic year 2020/2021
in order to study the effect of gibberellin GA3 on two cultivars of quinoa (Chenopodium
quinoa willd)
V4(Q18) and V7(Q27) under increasing concentrations of NaCl (S0= 0,
S1=200, S2=400, S3=600, S4=800, S5=1000) mmol/l during the germination stage, where
these cultivars were treated with gibberellin soaking in order to reduce the negative effects of
salinity .
The results we obtained confirmed the effect of salt stress on the germination of quinoa
seeds with the different response of the two cultivars to salinity, through the results of some
studied criteria for the germination process such as: germination percentage, germination
speed, germination stress index, dry matter tension index, salinity tension index, seedling
length, weight. Dry and soft. This study showed more positive results for the variety V7
(Q27) compared to the variety V4 (Q18), and therefore we can consider the variety (Q27)
more resistant to salt stress.
The obtained results showed that Nacl reduces the germination of quinoa seeds, and the
use of the phytohormone gibberellin GA3 helped to increase the resistance of the quinoa plant
to stress.
