    Effect of Storage Containers and Storage Periods on the Moisture Content, Germination and Biotic Status of Durum Wheat (Triticum turgidum L.) Seed

    To observe the moisture content and germination capacity of durum wheat seed stored in different storage containers for certain storage periods, a Lab. experiment was carried out at the Agronomy laboratory, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur, Bangladesh during March-May 2016. The experiment was designed completely randomized design (CRD) with three replications under three storage periods (30, 45, and 60 days after storage) and three seed containers (sealed plastic container, polythene bag and gunny bag). Initial seed moisture content (MC) and germination percentage (GP) was measured before storage of seeds. Seeds stored in containers gradually absorb moisture from air with the advancement of storage periods, and air leaked storage container i.e., gunny bag quickly absorb moisture than other two containers. The maximum values of GP were recorded of durum wheat seed with 30 days after storage (DAS) and the GP reduced significantly with increasing storage periods from 30 to 45 DAS. The highest GP (78.00 %) was found at 30 DAS in sealed plastic container while the lowest (57.67 %) at 60 DAS in gunny bag. The rate of reduction was found to increase with the advancement of storage periods. Durum wheat seed kept in sealed plastic container and ply bag maintained the minimum MC and eventually showed highest GP. An outstanding performance of GP was observed in sealed plastic container seed while the gunny bag provided the inferior GP among all of the three containers. Several fungi was observed such as Alternaria, Aspergillus, Colletotrichum, Fusarium, Penicillium and Rhizopus during germination study, although no insect was found to any storage container during the storage periods. Higher number of fungus was observed in seeds of gunny bag than sealed plastic container and poly bag. In conclusion, durum wheat seeds should be stored in air tight container for certain periods.

    Salinity Stress in Maize: Consequences, Tolerance Mechanisms, and Management Strategies
    (LIDSEN Publishing Inc, 2024) Islam, Mohammad Sohidul; Islam, Md. Rafiqul; Hasan, Md. Kamrul; Hafeez, A. S. M. Golam; Chowdhury, Md. Kaium; Pramanik, Moaz Hosen; Iqbal, Muhammad Aamir
    Maize, along with rice and wheat, is a popular staple food crop worldwide, and the most widely produced cereal crop. It is a versatile crop that may be utilized as a source of raw materials for human and animal fodders. Low agricultural yield and rapid population expansion significantly threaten future food security. Maize production is hampered by biotic and abiotic causes, with abiotic factors being the most critical limitation to agricultural output worldwide. Soil salinity is a key abiotic factor that reduces agricultural production by imposing negative impacts at several life cycle phases, including germination, seedling, vegetative, and reproductive development. Maize plants experience many physiological changes due to osmotic stress, toxicity of particular ions, and nutritional imbalance induced by salt stress. The degree and duration of stress, crop growth phases, genetic characteristics, and soil conditions influence yield reduction. Maize plants can tolerate salt stress involving a complex mechanism by changing their physiological, biochemical, and metabolic activities like stomatal functioning, photosynthesis, respiration, transpiration, hormone regulation, enzymes, metabolite generation, etc. After studying the salt tolerance mechanisms of maize plants under stress, integrated management techniques should be developed for maize agriculture in saline settings. Therefore, the study of plant responses to salt stress, stress tolerance mechanisms, and management strategies is one of the most imperative research fields in plant biology, and the study will focus on the effects of salt stress in different growth stages, plant tolerance mechanisms, and agronomic management practices for successful maize production all over the world. © 2024 by the author.
