Although cultivating bamboo provides solutions to part of these problems, the benefits of bamboo cultivation are species and site-specific. However, no research has established the ethnobotanical knowledge of bamboo in West Pokot, making it difficult to upscale its cultivation. The study aimed at 1) determining the level of awareness of bamboo 2) the uses of bamboo 3) factors motivating and hindering its cultivation. The study adopted an analytical cross-sectional survey research design. Simple random and purposive sampling techniques were used in selecting the study site. A Systematic random sampling technique was used in selecting households to be used in establishing local knowledge through questionnaires. Data were analysed using chi-square test of fit, chi-square test of association and cochran’s Q test of K-related samples. Results showed that farmer to farmer approach (38.9%) was the main source of information. Among the respondents, 70.6% of them were aware of bamboo out of which 67.6% were aware of its uses. The commonly identified uses were soil conservation (48.1%), shade provision (39.5%), fencing material (38.8%) and construction material (36.9%). The findings revealed that 74.1% of the respondents were willing to cultivate bamboo due to its environmental, economic and cultural benefits among others. However, inadequate knowledge of bamboo planting and management techniques (51.8%) is the main impeding factor to the cultivation of bamboo in the region. Therefore, forestry and agricultural extension agents in the county should sensitize and train farmers on bamboo establishment and management for farmers to realize its full potential","PeriodicalId":39305,"journal":{"name":"Journal of Bamboo and Rattan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135542214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The uncontrolled use of natural resources is currently causing the massive pollution of rivers in Sumatra, so the availability of clean water for people's lives is started to decrease. One of the efforts to conserve watersheds is to preserve riparian vegetation. Where there is a source of water, there is bamboo. Bamboo that grows in riparian areas has a root system that can prevent erosion and filter water, increasing clean water availability. The purpose of this study was to conduct an inventory, study of ecology, and indicate environmental factors of bamboo species that can potentially maintain riparian environmental conditions, which can later be developed as soil and water conservation plants in the Sumatran watershed. This research was conducted in the riparian areas in upstream of three major Sumatran rivers: Kuantan, Kampar, and Rokan. We recorded 20 species of bamboo plants from 5 genera in three major rivers of Sumatra. The Rokan watershed has environmental conditions that are still maintained with low human activity so that the diversity of bamboo upstream of the Rokan river is high and is still well maintained. Meanwhile, the Kuantan and Kampar watersheds have a lot of human activities along the river, so the bamboo vegetation has been exploited in these two areas. Based on Canonical Correspondence Analysis, Bambusa vulgaris is found suitable for cultivation in Kuantan and Kampar watersheds, which is abundant in these watersheds as well as has high tolerance range for polluted watershed. We recommend that B. vulgaris be used as riparian vegetation for soil and water conservation in polluted watersheds.","PeriodicalId":39305,"journal":{"name":"Journal of Bamboo and Rattan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88056354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mean values of ash contents of the bamboo culm growth stages across the three ecological zones were from 0.93% to 2.11%. The contents were within the threshold approved in the EN standards EN 14775 ≥3%. The mean values of carbon across the culm growth stages ranged from 48.46% to 53.31%. Hydrogen among the bamboo culms ranged from 5.60 to 7.04%. Higher carbon and hydrogen contents lead to higher heating values. Nitrogen among the culm growth stages ranged from 0.31 to 0.79%. The concentration levels of N in the culms were within the threshold prescribed in the EN standards EN 15104 ≥ 1%. The mean Cu concentration of mature culms ranged from 0.89-1.31 ppm; Zn ranged from 2.74-3.25 ppm; As varies from 0.055 to 0.078 ppm; Ni ranges from 0.43-0.85 ppm and Cd in the mature bamboo culm ranged from 0.81 to 3.66 ppm.

The composites were termed as “strip-board” and “shavings-board” to indicate that such was processed from shavings and strips, respectively. The strip-board was produced from 1.2 meter poles. The poles were turned into slats and were deskinned, denoded, and further processed into thin long strips. The shavings-board were made from the internodes converted into slats, deskinned, and processed into thin materials. During defibering, the vascular bundles were cooked in three varying NaOH-water concentrations (i.e., 1%, 3%, and 5%) for 3 hours. The cooked bundles were thoroughly washed and dried to 14% MC, applied with polyvinyl acetate, and pressed at 1000 psi. The produced boards were cured, dried, and samples were subsequently tested for tensile, compression, and bending strength following the ASTM D-143-22 standards. The data were analyzed using the 2×2×3 (i.e., species, board type, NaOH concentration) factorial experiment in CRD. Results showed that the pressing pressure used was insufficient to produce void-free boards. No interaction was noted between the three factors, but the main effect indicated that B. blumeana has significantly higher tensile and compression strength compared to D. asper. The strip-boards also obtained the same compared to shavings-boards. Despite the strength properties exhibited by B. blumeana, boards from D. asper were economical because of the lower price per pole and production cost. We conclude that the high pressing pressure was the most crucial factor in producing void-free, tightly compacted dense boards","PeriodicalId":39305,"journal":{"name":"Journal of Bamboo and Rattan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72644981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are indiscriminately harvested for commercial usage in paper, pulp, and traditional cottage industries. This has drastically affected its viable populations in the Western Ghats. SSR markers were employed for characterizing the selected natural population to assess genetic diversity and infer genetic structure in their natural distribution range. The marker analysis revealed existence of high genetic diversity in sampled populations of O. travancorica (He=0.834, I=2.092). Analysis of molecular variance (AMOVA) revealed that a large proportion of genetic variation (84 %) is confined within the populations and only 16 percent was observed between populations. The pattern of genetic admixture generated in STRUCTURE analysis revealed high level of substructuring of populations. This might be due to close proximities of populations and high amount of gene flow (Nm=1.456) among them. Genetically diverse populations as indicated by number of, private alleles, gene diversity, heterozygosity and polymorphic content in different geographical areas indicate the need for ex situ conservation and genetic improvement programmes. Periyar and Malayatoor populations with significant genetic admixtures can also be recommended for resource conservation of reed bamboo species.","PeriodicalId":39305,"journal":{"name":"Journal of Bamboo and Rattan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86202031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Growth parameters such as clump height, clump circumference (at 1.37 m), culm girth (at 1.37 m), internodal length and number of culms were observed in the field at periodic intervals of four months. The field result showed considerable variation in growth and productivity among the six bamboo species under study. Overall growth performance was better for B. vulgaris, D. brandisii and D. longispathus. For instance, B. vulgaris and D. brandisii were the toppers in terms of clump height, clump circumference and culm girth while B. tulda showed relatively poor growth for these parameters. Among the species, the highest internodal length was observed for D. brandisii and D. longispathus while B. tulda recorded the shortest internodal length. Number of culms per clump was highest for D. asper while it was the lowest for B. balcooa. Faster growth rendered by all the species except for B. tulda suggest their vast potential for integration in the farm lands of Kerala for enhancing the economic and ecological benefits to the farmers.","PeriodicalId":39305,"journal":{"name":"Journal of Bamboo and Rattan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77194666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a past study, it was established that the growth forms of D. strictus which developed over time in their respective locations, were genetically varied. The present research further explores the variations in their respective rhizospheric microbes and looks for the role of plant selection phenomenon. Considerable variation in mycorrhizal structures and in the functional diversity of Pseudomonas fluorescence was registered.
