Cultivating resistant varieties of potato is the most effective and environmentally safe method of protecting against pests and diseases that affect potato crops. Therefore, potato breeding is focused on developing more resistant varieties so that the use of plant health products can be reduced during the cultivation cycle. Resistance to late blight, viruses and nematodes is the most important ...

The production of mycorrhizal fungi provides higher economic returns than any other forest product in many Mediterranean woods. In these areas, truffles {Tuber spp.) and mushrooms of Boletus and Lactarius genus are the fungi that yield the highest economic benefits. However, there are still evident gaps in the understanding of the truffle's biological cycles, ecology and interactions with host ...

Tiger nut (Cyperus esculentus) tuber contains oil that is high in monounsaturated fatty acids, and this oil makes up about 23% of the tuber. The study aimed at evaluating the impact of several factors and enzymatic pre-treatment on the recovery of pressed tiger nut oil. Smaller particles were more favourable for pressing. High pressure pre-treatment did not increase oil recovery but enzymatic t...

The effects of two mineral and two organic acids, four organic solvents (methanol, ethanol, 2-propano and acetone) and three inorganic metal salts in combination with temperature regimes 0 and 22C on the yield and resolubility of potato tuber proteins were studied. Using acids, the yield of precipitated protein ranged from 22.3% (citric acid, 0C) to 54.5% (acetic acid, 22C) of total protein; ho...

Number of Pratylenchus spp. (primarily P. penetrans) were recorded at planting in experimental potato plots over a 9-year period at one location on Prince Edward Island. Tuber yields of 'Superior' and 'Russet Burbank' potatoes in plots treated with aldicarb were compared with yields in adjacent untreated plots. There was a linear relationship between the number of root lesion nematodes at plant...

potato is one of the sensitive plants to drought stress and it is one of the main crops in the north regions of fars province. since the planting time is simultaneous with wheat irrigation period, due consideration should be given to reduce irrigation consumption for this crop. this research investigated the effect of potassium sulfate on the drought tolerance of potatoes. field experiment was ...

concentration of co2 in the atmosphere is likely to increase up to 550 µmol mol-1 by the middle of 21st century. such an increase in the atmospheric co2 would affect plant growth, and as well the productivity of crop plants. a field experiment was conducted with two potato cultivars namely kufri surya and kufri chipsona-3 grown inside open top chambers (otcs) at ambient (385±30 µmol mol-1) vs. ...

Potato microplants were inoculated with three commercial arbuscular mycorrhizal inoculants, Vaminoc (MicroBio, Hemel Hempstead, HP2 7SU, UK), Endorize IV and Glomus intraradices (both produced by Societe Biorize, 21000 Dijon, France) at establishment in the glasshouse. Monitoring of percentage root length colonization confirmed the persistence of all the mycorrhizal fungi during the trial. Colo...

Micropropagation and minituber production technology may enable the establishment of potato (Solanum tuberosum L.) seed tuber certification programs in arid and semiarid regions of the world and reduce dependency on expensive seed tuber imports. Therefore, we investigated possible carry-over effects of moderate salt stress on the following production cycle. The yields of seed tuberand microtube...

This study was conducted to explore the changes in soil microbial populations, enzyme activity, and tuber yield under the rotation sequences of Potato-Common vetch (P-C), Potato-Black medic (P-B) and Potato-Longdong alfalfa (P-L) in a semi-arid area of China. The study also determined the effects of continuous potato cropping (without legumes) on the above mentioned soil properties and yield. T...
