  2. RESEARCH ARTICLE Analysis of Environmental Effects on Leaf Temperature under Sunlight, High Pressure Sodium and Light Emitting Diodes

    Jacob A. Nelson; Bruce Bugbee
    The use of LED technology is commonly assumed to result in significantly cooler leaf tem-peratures than high pressure sodium technology. To evaluate the magnitude of this effect, we measured radiation incident to and absorbed by a leaf under four radiation sources: clear sky sunlight in the field, sunlight in a glass greenhouse, and indoor plants under either high pressure sodium or light emitting diodes. We then applied a common mechanistic energy-balance model to compare leaf to air temperature difference among the radiation sources and environments. At equal photosynthetic photon flux, our results indicate that the effect of plant water status...

    The objective of this study was to identify the aggregation pheromone of the melon thrips Thrips palmi, a major pest of vegetable and ornamental plants around the world. The species causes damage both through feeding activities and as a vector of tospoviruses, and is a threat to world trade and European horticulture. Improved methods of detecting and controlling this species are needed and the identification of an aggregation pheromone will contribute to this requirement. Bioassays with a Y-tube olfactometer showed that virgin female T. palmi were attracted to the odour of live males, but not to that of live females,...

  6. MINI-REVIEW The plant strengthening root endophyte Piriformospora indica: potential application and the biology behind

    P. Franken
    Abstract The successful conversion of plant production sys-tems from conventional resource-exhausting to sustainable strategies depends on knowledge-based management of envi-ronmental factors. Root-inhabiting fungi came more and more into focus because their hyphae connect in ideal manner resources and challenges of the surrounding with the plant. A paradigm for such root endophytes is presented by the basid-iomycete Piriformospora indica. This fungus possesses a broad host spectrum and positively affects different aspects of plant performance. This so far unique combination of attrib-utes makes P. indica and its close relatives among the Sebaci-nales very interesting tools for cultivation of various crops. This review...

    spp.) and share most of the same diseases and pests. Almost every peach pest is also a plum pest, so most of the pest and disease information in ATTRAs Organic and Low-Spray Peach Production publication is applicable to plums as well. The present document, therefore, will be limited to problems and considerations peculiar to plums. Organic fertilization and weed control techniques are covered in ATTRAs Overview of Organic Fruit Production. Much of the basic information on tree fruit production will be the same whether the grower uses low-spray, organic, or conventional pest and fertility management. For instance, variety choices must...

  14. USE OF NANOTECHNOLOGY IN HORTICULTURE: A REVIEW

    Gurteg Singh; H S Rattanpal; Corresponding Gurteg
    The development of nanotechnology creates an excellent opportunity to address complex technical issues of food supply chain. Failure to embrace nanotechnology will deny the horticultural sector an opportunity to capitalize on improved product visibility, food safety, quality and security and associated economic benefits. Agricultural and food supply chain management is complex due to the diverse characteristics of agricultural products. There are numerous types of horticultural crops and products, many of which are perishable. In addition, the degree of standardization of some kinds of fruit products and their management is still low. In this regard, the potential application of nanotechnology to...

    Approximately 30 exotic ant species have been introduced into New Zealand, including the Argentine ant Linepithema humile (Mayr). Many of these ant species are known to affect horticulture worldwide by tending hemipteran insects. These ants may protect these hemiptera from their natural enemies, resulting in higher pest densities and potential economic loss. Our aim in this work was to survey the ant species associated with the various horticultural crops in the North Island. Our focus was on L. humile, but we also collected other ants and associated hemipteran species. Linepithema humile appeared to be an opportunistic species and was found...
