Exploratory surveys were carried out in the Andamans and Nicobar group of islands during 2006 and 2014 to locate wild species viz. Mangifera andamanica King, Mangifera camptosperma Pierre and Mangifera griffithii Hook. Not much variation was observed for fruit shape and size for the species Mangifera andamanica, which was endemic to this region. The species M. griffithii has been reported to be only in Mt. Harriet. However, another plant of M. griffithii in the Shoalbay region was found during the second survey. The foliage & fruit characteristics of the two specimens were similar, with a slight difference in the morphological features, which could be attributed to their origin from seeds. The DNA finger printing carried out showed minor changes in the species. The phylogenetic relationships amongst five Mangifera species viz. M. indica, M. griffithii, M. camptosperma, M. odorata and M. andamanica were analyzed by employing chloroplast markers viz., petB-petD intergenic spacer, rps16 gene, trnL-trnF intergenic spacer and nuclear marker—External Transcribed Spacer (ETS). The nuclear markers and chloroplast markers based on phylogenetic analysis showed that the common mango M. indica L. was closely related to M. griffithii and M. camptosperma, which belonged to subgenus Mangifera. However, M. odorata that belonged to subgenus Limus was grouped separately along with M. andamanica. The above results are in congruent with the accepted classification of genus Mangifera reported by Kostermans and Bompard with the exception of M. andamanica, which has been earlier classified under subgenus Mangifera. Results clearly indicated that classification of M. andamanica under subgenus needed to be reconsidered. 展开更多

评价了10个多功能树种--阿江榄江树(Terminalia arjuna)、印楝(Azadirechta indica)、牧豆树(Prosopis juliflora)、水黄皮(Pongarnia pin-nata)、木麻黄(Casuarina equisetifolia)、角豆树(Prosopis alba )、阿拉伯金合欢(Acacia nilot... 评价了10个多功能树种--阿江榄江树(Terminalia arjuna)、印楝(Azadirechta indica)、牧豆树(Prosopis juliflora)、水黄皮(Pongarnia pin-nata)、木麻黄(Casuarina equisetifolia)、角豆树(Prosopis alba )、阿拉伯金合欢(Acacia nilotica)、细叶桉(Eucalyptus tereticornis)、牛蹄豆(Pithecellobium dulce)、铁刀木(Cassia siamea )等10年间的生物量和生物能产量,这些树种采用单种栽培的农作方式种植于印度北部恒河平原苏打土壤。该地区土壤紧密、盐碱化、透水性差、营养匮乏。10个树种中,细叶桉植株最高,牧豆树和木麻黄次之。阿拉伯金合欢林分基面积为3.04m2·hm-2,植株胸径优于其他树种,牧豆树和木麻黄植株胸径次之。10年间,牧豆树和Acacia nilotica分别产出生物量56.50和50.75 Mg·hm-2,而阿拉伯金合欢、水黄皮和角豆树生物量产出量较小。牧豆树的营养需求和净生物量产出均最大,而且叶片中营养元素(N,P,K,Ca和Mg)含量较高。然而,树种间木质成分差异较小。以每吨木材营养元素产出量计算,氮素在阿拉伯金合欢中产出量最低,磷和钾分别在阿江榄仁树和牛蹄豆中产出最低,钙和镁在牧豆树中产出最低。牧豆树生物质能产量最高1267.75 GJ·hm-2,阿拉伯金合欢次之1206 GJ·hm-2,印楝最低(520.66GJ·hm-2)。图2表7参31。 展开更多

The present work aims to optimize the foaming conditions for tomato juice using three level Box-Behnken Experimental Design of Response surface Methodology. In the following study three process parameters namely concentration of egg albumin (EA) as foaming agent, Carboxy methyl cellulose (CMC) as foam stabilizer and whipping time (WT) was optimized. The levels for various input variables were EA: 5% - 15%, CMC: 0.10% - 0.60% & WT: 3 - 7 min. The responses measured were expansion volume (EV), foam density (FD) and drainage volume (DV) which are an indication of foaming ability and foam stability. The predicted levels of responses as generated by software were EV: 91.49%, FD: 0.558 g/cc & DV: 10 ml, which on validation was found closer to experimental value. 展开更多

The multiple uses of forests continue to draw interest from diverse stakeholders. Forest Management Teams model has been used to accommodate the interests of stakeholders and facilitate better forest management and improve community livelihoods through managed citizenship. In Kenya, the model has been practiced the longest in Arabuko Sokoke forest. This paper reviews the 25-year-old Arabuko Sokoke Forest Management Team using the Influence and Importance tool. The assessment demonstrates that Influence and Importance factors affect forest management either positively or negatively, fair and just use of this tool could lead to a team (citizenship) that is perpetually adapting to new tasks and emerging scenarios where local communities and stakeholders are empowered by new rights conferred to them by the partnership. In Arabuko Sokoke forest, the use of Forest Management Team has achieved enviable success in forest management, community livelihoods, organizational development and rural development—which are essential elements for forest citizenship. This paper documents how appropriate application of Influence and Importance tool bounded by external and internal actors can enhance an inclusive and adaptive participatory process. 展开更多
