Wendl.) H. Wendl. ex Benth. & Hook. f. that belongs to the same genus as sago palm (M. sagu Rottb.). Seedlings at the 11th to 13th leaf stages were used for the treatment of 342mM (2%) NaCl for 31 days in a phytotron at 30°C and 75% relative humidity under natural sunlight in mid-summer in central Japan. The Na+ and Cl- concentrations increased in the roots, petioles and leaflets with the NaCl treatment, while, the K+ concentration did not change in the top parts. The Ca2+ and Mg2+ concentrations increased in the leaflets, especially at lower and higher leaf positions, respectively. Leaf emergence and dry matter weight of the top parts were not affected by the NaCl treatment, whereas the transpiration rate decreased. It was, therefore, considered that salt avoidance to maintain the water status in the leaves by restricting the transpiration is important for the salt resistance of M. vitiense. The changes in the Ca2+ concentration can be considered to play a role in adequate absorption of K+, which would enable the plant to maintain osmotic adjustment in the leaflets.","PeriodicalId":118800,"journal":{"name":"Tropical agriculture and development","volume":"377 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132121006","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}

These bananas are more frequently cooked as staple food and snack, and used for brewing than eaten in the raw form. Each banana farming area has developed a unique set of cultivars°, cropping systems, and uses of bananas. Humid zones in the southern part of Ugandan, as well as Rwanda and western part of Tanzania, are famous areas for fanning unique banana cultivar subgroup called the East African highland bananas' (AAA-EA). As a conventional cropping system, it has extremely high productivity and supports local people in areas with one of the highest population density in Africa. However, in Uganda with population migration, land shortage, and pest and disease prevalence, areas that produced and supplied bananas to urban areas have drastically changed in the last half century. This paper reports the current situation of banana-based livelihood system of Nkore, formerly agro-pastoralists in Southwestern Uganda, presently the main banana producing area in Uganda. We describe their farming system, cultivars, uses, and distribution of bananas.","PeriodicalId":118800,"journal":{"name":"Tropical agriculture and development","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115720726","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}
