  • Ozone impacts on assimilation and allocation to reproductive sinks in the vegetatively propagated C4 weed, yellow nutsedge

    Crop production in many irrigated agricultural regions is challenged by both air pollution and weed pressure. Impacts of ozone (O3) on C4 plants have received little attention. Yet many important crops and weeds utilize the C4 pathway, including yellow nutsedge (Cyperus esculentus L.). A previous study suggested that this species may respond to O3 exposure with enhanced allocation of ...

  • Plant regeneration from zygotic embryo-derived embryogenic cell suspension cultures of Ranunculus kazusensis

    Culture conditions for high frequency plant regeneration via somatic embryogenesis from cell suspension cultures of Ranunculus kazusensis are described. Zygotic embryos formed white nodular structures and pale-yellow calluses at a frequency of 84.9% when cultured on half-strength Schenk and Hildebrandt (SH) medium supplemented with 0.1 mg l−1 2,4-dichlorophenoxyacetic acid (2,4-D). However, ...

  • Growing substrates for aromatic plant species in green roofs and water runoff quality: pilot experiments in a Mediterranean climate

    Green roof technology has evolved in recent years as a potential solution to promote vegetation in urban areas. Green roof studies for Mediterranean climates, where extended drought periods in summer contrast with cold and rainy periods in winter, are still scarce. The present research study assesses the use of substrates with different compositions for the growth of six aromatic plant species ...

  • Total phenol content of guava fruit and development of an in vitro regeneration protocol amenable to genetic improvement

    Total soluble phenolics in two white ('Allahabad Safeda' and 'Lucknow–49'), two pink ('Beaumont' and 'Gushiken Sweet'), and three red fleshed ('Ka Hua Kola', 'Ruby Supreme' and 'Red Fleshed') guava (Psidium guajava L.) fruits were assessed using the Folin–Ciocalteu procedure. 'Allahabad Safeda' and 'Ruby Supreme' contained the highest level of phenols (1,967.5 and 1,921.25 g/g gallic acid ...

  • Grow to Order and Seed Collection

    Local provenance planting is important to help restore our natural habitats and retain the genetic integrity of plant populations and is strongly recommended for projects within or near environmentally sensitive areas. Forward planning is essential when undertaking local provenance seed collection as there are seasonal constraints such as seed maturation time, finding seed donor sites and gaining ...

  • Technical efficiency of organic tea smallholding sector in Sri Lanka: a stochastic frontier analysis

    Organic tea is emerging as a major farming activity in Sri Lanka. In this paper, using a stochastic frontier analysis, we analyse the technical efficiency of organic tea smallholdings in the mid country wet zone of Sri Lanka. The Cobb-Douglas functional specifications are found to be an adequate representation of the cross-sectional data obtained in 2002. Our results indicate that there is great ...

  • A comparative study of multiple linear regression, artificial neural network and support vector machine for the prediction of dissolved oxygen

    Dissolved oxygen (DO) is an important indicator reflecting the healthy state of aquatic ecosystems. The balance between oxygen supply and consuming in the water body is significantly influenced by physical and chemical parameters. This study aimed to evaluate and compare the performance of multiple linear regression (MLR), back propagation neural network (BPNN), and support vector machine ...

  • Article: Consultative Opinion on Liability of Public and Private Actors for Genetic Contamination of Non-GM Crops

    By ICEAC Chamber of Consults     The basic claim of the request is formulated in the following terms: in case of GMO contamination in non-GMOs crops, especially in absence of national legislation, who is responsible to pay the damage among all the different public and private actors involved in the GMO chain of production, distribution and ...


  • Technology for life? Or technology for death?

    Mostly business people are  honest in their dealings. They work honestly with their customers. Most of the machinery manufacturers and suppliers have a tendency to make and sell bigger and bigger machines. Naturally bigger machine has bigger profit. So everybody is tempted to  sell bigger machines and bigger plants. They take satisfaction that they are working honestly. They are ...

  • `Good Agricultural Practices’ in the Agri-food Supply Chain

    Keywords: Voluntary private standard schemes, food quality, food safety, ethical production, environmental standards, SPS Agreement, TBT Agreement, market entry barriers, product liability. Abstract: Criteria defining 'good agricultural practice' (GAP) were originally developed for on-farm production methods and resource use. For a decade, GAP principles have been applied ...


  • Coffee production systems

    Types of production systems Roughly, five types of coffee production systems can be distinguished (Moguel, 1996, in Courville, forthcoming): 1)Traditional rustic coffee system: coffee production under forest trees by substitution of plants growing on the floor of a (sub)-tropical forest with coffee. There is a minimal impact on the original forest ecosystem; 2)Traditional polyculture system ...

  • Soil and water: towards a larger-scale perspective of their relations

    Land use changes over time have altered relations between soils and water cycles throughout Europe. There are regions where forests were cut for agriculture or herding, or for industrial, mining, and/or railroad use. Soils were lost, through mud floods, and the water cycles changed so that their present status is one of badlands and/or desert-like areas. Early stages in the path to degradation ...

  • Bamboo: The Secret Weapon in Forest and Landscape Restoration?

    In the world of forestry, bamboo doesn’t always get the credit it deserves. Dismissed as a weed or marginalized in traditional forest management, bamboo could actually play an important role in forest and landscape restoration. With adequate attention, investment, and the right standards in place, it could become ...
