Evaluation of Tolerance of Several Corn Genotypes (Zea mays L.) to Salinity Stress at the Germination Stage
Abstract
Corn (Zea mays L.) is a vital food crop with the potential to enhance food supply and support other sectors, such as livestock production. This study aims to determine the level of salinity stress that can be utilized to select maize genotypes tolerant to such stress. The research was conducted in the greenhouse of the Maros Cereal Research Center (Balitsereal) starting in February. The experimental design employed a split-plot arrangement consisting of two factors. The main plot consisted of five levels of NaCl concentration: no salinity stress and concentrations of 30, 60, 90, and 120 mM. The subplot included eight maize genotypes. Each treatment combination was replicated three times. Corn seeds were germinated for five days in petri dishes lined with germination paper, with ten seeds per dish. Afterward, the seeds were treated with NaCl and distilled water. The germinated seeds (after 5 days) were then transferred to the next germination medium, specifically styrofoam. At the germination stage, the tolerance selection of several corn genotypes under salinity stress revealed that NaCl concentration significantly affected plumule length, root length, and the number of roots. As the NaCl concentration increased, plumule length, root length, and the number of roots decreased. Additionally, genotype significantly impacted root length, the number of roots, and the percentage of seed growth. The results of the variance analysis indicated that there was no interaction between NaCl concentration and genotype at the germination stage.
