Summary: This study evaluated the physiological and growth responses of potted mandarin plants to the application of polyacrylamide gel in water restriction conditions. The results showed that although the substrate moisture was higher in the treatment with polyacrylamide gel, it did not improve the plant's water status or growth. On the contrary, plants treated with polyacrylamide gel had lower biomass and poorer root conditions.

Summary: The study evaluated resistance of 19 sainfoin accessions to powdery mildew, identifying sources 15353 and 3001 as resistant, Oshnavieh and Polycross as semi-resistant, and others as susceptible. Resistant accessions exhibited high yields and quality traits, with powdery mildew severity negatively correlated with quality indicators. Sources 3001 and 15353 were found stable across locations, suggesting their potential for future breeding programs. Continuing evaluation of sainfoin germplasm is recommended to identify further resistant accessions.
