The availability suggests the need for Phenetic analysis of Polypodiaceae in Nagarawagi Village to facilitate the classification of ferns as well as create a database of flora and fauna diversity in Indonesia. Therefore, this study aimed to determine the species and … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 7 Aug 2026 · 889 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDifferences in the Response of Diploid and Tetraploid Anthurium andraeanum Seedling Roots to Salt StressYun Zhang, Yongping Zhang, Yongxu Qiao et al.To investigate the effects of salt stress on the growth, development, and endogenous hormone content of roots in diploid and tetraploid seedlings of Anthurium andraeanum, the enhanced salt tolerance was elucidated. The seedlings of A. andraeanum 'Pink champion' were placed at NaCl concentrations of 0, 50, 100, 150, and 200 mmol·L⁻¹. The results indicated that NaCl stress can reduce leaf … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 29 Jan 2026 · 1,776 accessesView PDF Cite

Research ArticleOpen accessIn the abstractResponse of Cowpea (Vigna unguiculata L. Walp.) Varieties to Striga gesnerioides (Willd.) Vatke InfestationAlhassan Bawa, Ismael Yakubu, Yussif SeiduProduction of cowpea within the sub-Saharan Africa, and Ghana in particular, is bedeviled with many challenges, including Striga infestation, resulting in abysmal low grain and biomass yields. Thus, the study was conducted to evaluate Striga's impact on cowpea growth and yield. During the 2023 agricultural season, the study was carried out in Northern Ghana. A control (non-infested) experiment and a … …American Journal of Agricultural and Biological Sciences, Vol. 20, Issue 1 · 18 Sep 2025 · 4,867 accessesView PDF Cite

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 PDF Cite
