提高无铅皮蛋色香味的试验研究

无铅皮蛋的凝固性和色香味较差，根据皮蛋成熟过程的化学变化和机理，经过多次试验，研究总结出可以通过调整料泥的碱含量，提高加工温度和增长密封时间，加速无铅皮蛋的凝固性和提高色香味风味，达到国家商品和卫生质量标准，推广无铅皮蛋。试验结果表明：气温２０℃左右，滚粉法每１００个鸭蛋加纯碱１９０—２００克，生石灰２８０—３００克，密封１４—１６天。气温２５℃左右，每１００个鸭蛋加纯碱１６０—１７０克，生石灰２４０—２６０克，密封１４—１６天，必要时，可根据具体情况，调整密封时间。

几种鉴定小麦背景中1BL/1RS易位染色体的分子标记方法比较研究

对 5种鉴定小麦背景中 1BL/ 1RS易位染色体的生化和分子标记方法 ,包括酸性聚丙烯酰胺凝胶电泳 (A PAGE)、荧光原位杂交 (FISH)、RFLP、RAPD和特异性PCR标记 ,进行比较研究。结果表明 ,RAPD标记难以鉴定1BL/ 1RS易位染色体 ,其余均能对 1BL/ 1RS易位染色体进行有效鉴定。FISH和RFLP方法比较费时费力且花费昂贵 ,而特异性PCR标记又在一定程度上受模板DNA浓度的影响。据此认为 ,APAGE方法是一种简单、快速、经济有效的方法 ,最易于在小麦育种选择中应用     

The ecology and management of the Miombo woodlands for sustainable livelihoods in southern Africa: the case for non-timber forest products

There is new and increasing emphasis on the contribution of non-timber forest products (NTFPs) to improving the livelihoods of rural communities and therefore the need for sustainable management of forest ecosystems of the Miombo woodlands to ensure the continued availability of these NTFPs. This paper examines and reviews some of the work that has been done in the Miombo ecoregion on the ecology, utilisation and management of the Miombo woodlands. The review points to the richness of the Miombo regions' plant species, with an estimated 8 500 species of higher plants, of which over 54% are endemic. The review also highlights the response of the Miombo ecosystem to fire and other anthropogenic processes and the lack of wide-scale adoption or implementation of the major research findings. The review shows that there is a wide range of NTFPs that significantly contribute to the total household income in forest areas and to the national economies through provision of opportunities for small-scale trade especially in the rural areas. However, there is a concern that commercialisation usually results in overexploitation of the resource by the outsiders who become the major players. It is suggested from the review that the lack of capacity by national institutions to manage Miombo woodland resources could be addressed by using participatory approaches to natural resource management. It is also proposed that for sustainable use and management of NTFPs in the Miombo region, research should focus on issues that specifically address NTFPs. In order to facilitate commercialisation and benefit the economically weak, policies that incorporate postharvesting technical assistance and access to information on markets, technology and microcredit should be developed and promoted.

Patterns and processes of carbon, water and energy cycles across northern Australian landscapes: From point to region

Savannas comprise a large proportion of the terrestrial land surface and are highly varied in their composition, structure and function. These characteristics alter land-atmosphere exchanges of heat, water, carbon dioxide and other trace gases, which feed back to the climate at multiple scales. Australian savannas provide significant ecosystem services and further systematic scientific study is needed to sustainably manage these ecosystems. We undertook an interdisciplinary research effort to understand the patterns and processes of carbon, water and energy cycles across northern Australian landscapes across scales from point to region. We quantified the land surface-atmosphere exchanges across the vast region of Australian savannas using a hierarchical, integrated measurement and modelling approach to determine regional greenhouse gas and water budgets. The research team comprised groups from seven institutions and four countries. The research effort comprised of a multi- year measurement and modelling endeavour and culminated in an intensive field program held in September 2008 (late dry season). The program aimed to improve our knowledge of the spatial and temporal variability of land-atmosphere exchanges and the processes driving them as well as our ability to remotely sense them and simulate them using land surface models, which are crucial components of Global Climate Models. We attempted to robustly integrate small scale processes, such as leaf photosynthesis to larger scales applicable to modelling and remote sensing for the savanna region. In this paper we provide the scientific background and our overall approach to the program with reference to the papers in this “Savanna Patterns of Energy and Carbon Integrated Across the Landscape” (SPECIAL) issue.
