Artificial Pollination of Japanese Pear and Kiwifruit Using Electrostatic Pollen Dusting Machines

Electrostatic forces in wind-pollination—Part 1: Measurement of the electrostatic charge on pollen

Under fair weather conditions, a weak electric field exists between negative charge induced on the surface of plants and positive charge in the air. This field is magnified around points (e.g. stigmas) and can reach values up to 3 10Vm . If wind-dispersed pollen grains are electrically charged, the electrostatic force (which is the product of the pollen’s charge and the electric field at the po...

scour modeling piles of kambuzia industrial city bridge using hec-ras and artificial neural network

today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

Effect of Pomegranate, Grape and Kiwifruit Juice and Extract on Postharvest Quality of Intact Pear Fruits

Fruits and vegetables contain an array of antioxidant compounds. In this experiment, the effect of pomegranate, grape and kiwifruit juice or extract viz., pomegranate husk on pear fruits were investigated and compared with chitosan 1.5% and distilled water (control). The changes in the ascorbic acid, total soluble solids, total acid, weight loss, firmness and peroxidase and polyphenol oxidase a...

Electrostatic forces in wind-pollination—Part 2: Simulations of pollen capture

During fair-weather conditions, a 100Vm 1 electric field exists between positive charge suspended in the air and negative charge distributed on the surfaces of plants and on the ground. The fields surrounding plants are highly complex reaching magnitudes up to 3 10Vm . These fields possibly influence the capture of charged wind-dispersed pollen grains. In this article, we model the electric fie...
