When the potato planter works on sloping field, it will cause problems such as poor film mulching quality due to difference in volume of soil covering both sides discs and inconvenient adjustment disc. The device with linkage differential was designed improve quality. main research content includes explaining structure principle analyzing structural parameters mechanism. field experiment comple...

Current study aimed to search for safe and effective natural products to control the potato soft-rot disease, Erwinia carotovora subsp. carotovora. Antibacterial efficiency of edible mushroom extracts (MEs) and garlic essential oil (EO) were compared with two bactericides; streptrol and oxolinic acid as well as two fungicides; mancopper and copper oxychloride. Bioassay experiments were conducte...

According to traditional knowledge, Fagonia cretica has medicinal potential, especially against cancer and tumors. In the present study, this information was analyzed at laboratory level by performing cytotoxic, antitumor (potato disc) and DNA damage assay. Significant cytotoxic activity was found against brine shrimps at LD50 118.89 ppm, while antitumor assay showed that the extract inhibited ...

Hedera nepalensis is a ground-creeping evergreen woody plant growing mainly in the Himalayas and Kashmir. This plant is frequently used in folk medicines for the treatment of various ailments. The present research focused on the pharmacological evaluation and phytochemical analysis of crude methanolic extract (CME) and three fractions, n-hexane (nHF), ethyl acetate (EAF) and aqueous (AQF). The ...

potato is one of the main crops which is suffering from the great losses in storage and the most conventional method of its tuber rot is using hazardous chemicals. using antimicrobial potential of lichens can be one of the safe, green, environment friendly methods for plant diseases management. in this study, antimicrobial activity of acetone, methanol, chloroform extracts of ramalina capitaat,...

Sweet potato is grown extensively from tropical to temperate regions and is an important food crop worldwide. In this study, we established detection methods for 17 major sweet potato viruses using single and multiplex RT-PCR assays. To investigate the current incidence of viral diseases, we collected 154 samples of various sweet potato cultivars showing virus-like symptoms from 40 fields in 10...

The study examined the effect of ploidy elevation through unreduced gametes on transgene expression in potato. Tetraploid transgenic progenies were obtained from one tetraploid potato cultivar crossed with 2n pollen producing diploid clones harbouring an exogenous transgene (cry3Aa). Both singleand multiple-insert diploid transgenic lines that were regenerated by Agrobacterium tumefaciens leaf ...
