A grafting robot based on cleft grafting method has been developed to improve efficiency of grafting solanaceae vegetables. This robot consists of four parts including a clamping manipulator and carrying, cutting, feeding mechanisms. These not only enable the robot to conveniently perform clamping, carrying, positioning, cutting, joining, and binding rootstock and scion, but also improve the gr...

a principal obstacle facing intensive pear orchard establishment in iran is the absence of appropriate dwarfing or semi-dwarfing rootstocks, compatible with commercial cultivars, as well as showing adaptability with alkaline soils. this research aimed at an evaluation of the hawthorn seedlings (crataegus sp.) as a potential dwarfing rootstock for pear and a comparison of its dwarfing effects wi...

The effect of different pre-sowing seed treatments and sowing dates on germination and rootstock quality of ber was assessed to standardize a combination which could yield optimum germination and quality rootstock. Of the fourteen pre-sowing treatments, highest seed germination and best seedling growth was obtained in T10 x D2 (seed soaking in water for 48 hours followed by 6 days storage in mo...

The aim of this study is to analyze the effect excess boron (B) on nutrient uptake, growth, and physiological performance grapevines. Merlot Cabernet Franc grapevines, either own-rooted or grafted onto 1103P 101-14 Mgt rootstocks, were exposed in a hydroponic pot experiment 0.5 mM for sixty days. Twenty-five days following beginning B treatment, first symptoms toxicity appeared, including leaf ...

Abstract Warm and semi-arid climates are characterized by rainfall scarcity, resulting in the frequent use of low-quality water for irrigation. This work was undertaken to study effects stress saline irrigation on yield grape composition Monastrell grapevines grafted onto 1103P rootstock. The experiment carried out during three consecutive seasons a commercial vineyard located Jumilla (SE Spain...

This paper reviews preparation and applications of amylose supramolecules by means of phosphorylase-catalyzed enzymatic polymerization. When the enzymatic polymerization of α-D-glucose 1-phosphate (G-1-P) as a monomer was carried out in the presence of poly(tetrahydrofuran) (PTHF) of a hydrophobic polyether as a guest polymer, the supramolecule, i.e., an amylose-PTHF inclusion complex, was form...

This paper reviews the architecture of amylose supramolecules in form of inclusion complexes with synthetic polymers by phosphorylase-catalyzed enzymatic polymerization. Amylose is known to be synthesized by enzymatic polymerization using α-d-glucose 1-phosphate as a monomer, by phosphorylase catalysis. When the phosphorylase-catalyzed enzymatic polymerization was conducted in the presence of v...

The demand for an accurate financial risk management involving larger numbers of assets is strong not only in view of the financial crisis of 2007-2009. Especially dependencies among assets have not been captured adequately. While standard multivariate copulas have added some flexibility, this flexibility is insufficient in higher dimensional applications. Vine copulas can fill this gap by bene...
