Comparison of salinity tolerance of selected hemp genotypes grown in vitro

Janošťáková, Barbora

Salinity stress is a threat for present population, but most importantly for future generations. Salinization of soil is a current issue, which should not be underestimated. Most of the usual crops are not physiologically adapted to survive in saline soil, which means reduced yields of edible plants. As the population grows and the harvest decreases, it is becoming clear that the ratio is getting imbalanced and there is a serious threat of food shortage. This thesis aims to assess and follow the negative effects of NaCl on hemp plants which have been cultivated in vitro. The impact of NaCl was monitored and recorded. The results were shown in graphs, which helped to evaluate more clearly the effect of NaCl on hemp plants. NaCl affected morphology and specific physiological parameters of Beniko and Fibrol hemp breed. The results clearly show the influence of increasing NaCl concentration on plants including changes at the cellular level.
