Research ArticleOpen accessIn the abstractGrowth Characters, Physiology and Leaf Fall Disease Resistance in Immature Plants of Rubber (Hevea brasiliensis) IRR 400 Series ClonesRahayu Novrina Rosa, Mohammad Basyuni et al.Superior rubber clones have been used in Indonesia, but productivity achievements are low. The area and rubber production in 2020 was 3,316,047 ha with a productivity of 1,022 kg/ha. The low productivity is caused use of seedling materials. Adaptation testing is one of the stages for selecting superior rubber clones in various environmental conditions, the influencing factors are clone or … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 22 Mar 2024 · 5,300 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Root Rot in Soybean Cultivars with Diverse Susceptibility to the Disease on Plant Physiology, Yield, Amino Acids and Mycotoxins Profile in Climatic Conditions of KazakhstanNurlan Kuldybayev, Yerlan Dutbayev, Bozena Lozowicka et al.Soybean is an important high-value crop but susceptible to soil-borne diseases. A field trial was conducted in Kazakhstan to evaluate the effects of soybean cultivars and Fusarium root rot severity on soybean crop physiology, chlorophyll fractions and amino acids profile. The highest yield was achieved in 2018 (up to 4 t ha-1) for K-9648 cultivar. The greatest root rot severity … …OnLine Journal of Biological Sciences, Vol. 21, Issue 4 · 27 Dec 2021 · 6,299 accessesView PDFCite
