abstract striped rice stem borer, chilo suppressalis walker (lepidoptera: pyralidae) is one of the important pests in rice fields of mazandaran. therefore, almost the farmers of northern iran apply several pesticides in nurseries for the pest control; while it is causes environmental risks and damages to human. in this research two different items including, 1- study of egg masses density in nu...

Abstract Homestead resource utilization is widespread in Asia, while centuries of traditional approaches have been increasing throughout South Asia. resources are vital to maintaining sustainable life and livelihood local people Bangladesh remote areas as coastal zones mostly engaged with their homestead resources. The study was conducted Sandwip Upazila (sub-district) Chittagong district asses...

Recent advance of bioinformatics and analytical apparatuses such as next generation DNA sequencer (NGS) and mass spectrometer (MS) has brought a big wave of comprehensive study to biology. Comprehensive study targeting all genes, transcripts (RNAs), proteins, metabolites, hormones, ions or phenotypes is called genomics, transcriptomics, proteomics, metabolomics, hormonomics, ionomics or phenomi...

Variations in ̄avonoid and chlorogenic acid levels within fruit, within tree, between orchards, between cultivars and among mutants were characterised and quanti®ed in `Elstar' and `Jonagold' apples by reversed-phase high performance liquid chromatography (RP-HPLC). The sun-exposed skin of individual fruit had much higher cyanidin 3-galactoside (anthocyanin) and quercetin 3glycoside levels than...

The dynamic relationship between the rates of water loss and uptake controls plant water status. Marked diurnal variations in water potential of both leaves and fruit occurred in all plants studied. Variations in water status during the day were most clearly related to changes in evaporative demand of the air and were different for the east and west sides of a tree. At night, the plant water po...

Development of disorders during postharvest ripening and storage of fruit depends on a range of preharvest factors. The most obvious of these is maturity of fruit at harvest. However, a number of other factors may be just as important in ripening-related disorders and in determining how fruit respond to low temperatures or other imposed postharvest conditions. Fruiting position on the tree and ...

In southern pine seedbeds, weed control relies on the use of diphenylether herbicides (oxyfluorfen, lactofen) and selective grass herbicides (sethoxydim and fluzifop-p-butyl). A number of nurseries use a polymer to stabilize the soil after sowing. This helps keep the herbicide barrier intact and extends the preemergence activity. Weekly postemergence applications of low rates are common and hav...

In this paper, a cooperative visual servo controller is presented for autonomous citrus harvesting. A fixed camera provides a global view of a tree canopy for the camera-in-hand, attached to the end-effector, to servo to a target fruit. The paper focuses on the development of a robust, image-based, nonlinear visual servo controller to regulate the end-effector to the fruit location in the prese...
