“…Hence, the use of the micropropagation approach can address this problem. This technique has been widely utilized in the agriculture and forestry sectors for large-scale production of high-quality plant materials that are free from any infections, which is necessary for biomass production (Oseni et al 2018;Chawla et al 2020).…”

Energy consumption in human society has increased as more energy supplies are required to meet the needs of the world’s growing population. However, there is a major concern about fulfilling energy demand while reducing reliance on fossil fuels. Bamboo-based biomass has great potential for use as a raw material for the production of biofuels and bioenergy. Bamboo possesses excellent fuel qualities that can be converted into solid, liquid, and gaseous biofuels. Hence, the cultivation and harvesting operations must be performed efficiently to ensure that the availability of this biomass is sufficient to meet the demand for biofuel production. Several studies have shown that the micropropagation technique has increased bamboo production and that proper bamboo plantation management can benefit both the environment and society. Nevertheless, there are several challenges in bamboo cultivation and biofuel production, such as environmental impact from land management and economic risk from the industrial supply chain. Bamboo-producing countries, including Malaysia, have initiated several policies to propose strategies for sustaining the bamboo industry.

“…Availability of and easy access to diverse plant germplasm, including cultivation crops, their wild relatives, and wild species, are of great importance to human survival and contribute to people's livelihood via staple and cash crop breeding [1], pharmaceuticals [2], rehabilitation [3], environmental beautification [4,5], and ecological governance and stabilization [3]. Vegetatively propagated plants shipped by wrapping the plant or vegetative mass in express containers for long-distance transportation increases the risk of quarantine and environmental contamination [6].…”

“…Thus, a safe and efficient method for plant germplasm transportation, especially for vegetatively propagating plants, is needed. Micropropagation, which exploits the totipotent nature of plant cells to generate new individuals from protoplasts, cells, undifferentiated masses of cells (callus), small pieces of tissue, and/or excised organs, is a time-tested and practical ex situ technique for the short-and medium-term conservation of plant germplasm [2,7,8].…”

Shipping of in vitro micro-cuttings in tubes or jars is a frequently used method as the plants are more likely to quickly reproduce and comply with quarantine regulations in plant germplasm distribution. However, these containers are fragile during transportation. To diminish the risk associated with the long-distance shipping of in vitro plants, a safe and widely applicable packing and conservation technique based on microplate and slow growth was developed in this study. Potato cultivar ZHB and ginger cultivar G-2 were used to optimize the system with microplates (96 wells), vacuum-sealed packaging, and slow-growth techniques. Under regular culture conditions, packing in vacuum-sealed microplates reduced the survival of ZHB and G-2 micro-cuttings to 85.8% and 20.0%, respectively, and regeneration to 61.8% and 0%, respectively. Reducing the temperature to 10 °C maintained the survival of ZHB and G-2 micro-cuttings in the range of 83.3–100% after 60 days. Exposure to darkness decreased the survival of G-2 and inhibited regrowth. Thus, conservation in darkness at 10 °C is suggested. The effects of iron concentration and plant growth retardants were further assessed. The addition of 1/4 MS medium combined with 100 mg/L chlormequat chloride (CCC) resulted in full survival and growth inhibition of plantlets, without malformation identified. Finally, incubation with 1/4 MS medium supplemented with 100 mg/L CCC in vacuum-sealed microplates at 10 °C in the dark resulted in high survival and suppressed germination. Sweet potato HXS was incubated as well to test the broad-spectrum applications of the technique; 100% survival and 6.7% germination was gained. Morphological indices of released cuttings recovered to control levels after two cycles of subculture in MS medium. A 0.1–0.2% genetic variation was detected by SSR and ISSR, suggesting genetic stability of the conserved samples. Finally, micro-cuttings were safely transported to cities located thousands of kilometers away without package and sample damage. Our results enable easy distribution of in vitro plant germplasms.

“…By taking into account techniques like RS and GIS, the current study classi ed groundwater likely zones in and around the Srikakulam area and AHP techniques ). Remote sensing is a method used for collecting physical data from the objects on earth without any physical contact and that data is to be integrated in GIS (Chawla et al 2020). Groundwater studies frequently employ high-resolution satellite images because of their excellent spectral and spatial resolution (Golekar et al 2015;Suganthi, Elango, and Subramanian 2013).This study mainly emphasizes the application of slope, rainfall, drainage density, lineament density, topographic wetness index, soil texture, land use and landcover, lithology, land surface temperature, curvature, elevation, groundwater depth were combined by the weighted index analytical hierarchy process (AHP) method to produce the groundwater potential zones ; Ifediegwu 2022; Igwe, Ifediegwu, and Onwuka 2020).…”

Groundwater supplies across the world are under tremendous strain due to overuse and noticeable climatic changes over time. The requirement to assess groundwater potential and aquifer productivity rises along with the global need for potable water for human consumption, agriculture, and industrial applications. Because they are quick and will give first-hand knowledge on the resource for future projects, geographic information system-based studies have recently become quite popular in groundwater exploration. With this in mind, the current work uses remote sensing and GIS techniques to select and define groundwater potential zones for the evaluation of groundwater availability in the Srikakulam district of Andhra Pradesh, India.In the current work, an analytical hierarchical process approach (AHP) was combined with a geographic information system. For the purpose of defining the groundwater potential zone, a total of 12 thematic layers, including slope, rainfall, curvature, soil, drainage density, lineament density, topographic wetness index, land surface temperature, elevation, land use & land cover, lithology, and groundwater fluctuation, were taken into consideration. According to their qualities and water potential capacity as determined by the AHP technique, weights are allocated to each class in all thematic maps. To determine the groundwater potential zones, overlay analysis was performed after the creation of all the maps. The resulting groundwater potential zone map, which had a ground water potential index of 33, was divided into five classes which are ranging from very high to very low.
