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 ...

The impacts of fosthiazate on potato (Solanum tuberosum) tuber yields and populations of root lesion nematodes (primarily Pratylenchus penetrans) were studied during 1991-1994 in experimental plots on Prince Edward Island. Tuber yields were greater in treated plots when compared to untreated plots by 8% and 30% during 1991 and 1993, respectively. Numbers of nematodes in roots were reduced by th...

a 16-year-old class ii female patient was treated without tooth extraction. the upper first molars were distalized by the pendulum appliance. after six months, the molars tipped significantly to the distal. to correct this side effect, we decided to upright the molars using skeletal anchorage. on each side, a mini-screw was inserted between first and second premolars in the buccal cortical plat...

Maximum potato (Solanum tuberosum L.) tuber yields occur when an active plant canopy is maintained until normal plant maturation. Plaid nutrient concentrations and uptake rates play a major role in maintaining an active plant top. The objectives of this study were to relate the plant P concentrations to the P and dry matter balance between tuber and total plant growth needs. Growth analysis dat...

This study examined the effects of season-long exposure to elevated carbon dioxide (CO2) and/or ozone (O3) on tuber quality in potato (Solanum tuberosum L. cv. ‘Bintje’). Stands of potato were grown to maturity in open-top chambers (OTCs) in 1998 and 1999 under a factorial combination of three CO2 (ambient, 550 and 680 mol mol−1) and two O3 levels (ambient and elevated; 8 h per day seasonal mea...

Rapid wound-healing is crucial in protecting potato tubers from infection and dehydration. Wound-induced suberization and the accumulation of hydrophobic barriers to reduce water vapour conductance/loss are principal protective wound-healing processes. However, little is known about the cognate mechanisms that effect or regulate these processes. The objective of this research was to determine t...

in order to study of yield and qualitative characteristics of potato (aola variety), an experiment was conducted in mashhad conditions under irrigation regims and different levels of potassium fertilizer. this experiment was based on randomized copmpletely block with split plot design with three replications in khorasan razavi agricultural and natural resource research center in 2010. three lev...

The uptake and distribution of Cd in potatoes over the course of a growing season was investigated in two cultivars of potatoes that differed in tuber Cd concentration. Plants were grown in soil with supplemental Cd. The concentrations of Cd in different tissues varied greatly in the order roots>shoots>> tubers. After the initiation of tuber bulking, shoot growth ceased and the increase in tota...

Methods to identify Pinelliae Tuber and Arisaematis Rhizoma are required because of frequent reciprocal substitution between these two herbal medicines and the existence of several closely related plant materials. As a result of the morphological similarity of dried tubers, correct discrimination of authentic herbal medicines is difficult by conventional methods. Therefore, we analyzed DNA barc...

Potato late blight, caused by the oomycete phytopathogen Phytophthora infestans, is a devastating disease found in potato-growing regions worldwide. Long-term management strategies to control late blight include the incorporation of host resistance to predominant strains. However, due to rapid genetic changes within pathogen populations, rapid and recurring identification and integration of nov...
