Deep tillage of compacted soils can improve potato (Solanum tuberosum L.) tuber yield and quality if no other production factors are limiting. We hypothesized that within-row subsoiling and N placement would affect tuber yields and availability of plant nutrients. Potato (cv. Russet Burbank) was grown after winter wheat (Triticum aestivum L.) in 1989 and after dry bean (Phaseolus vulgaris L.) i...

In order to investigate the effect of different levels of biological fertilizers on potato performance (cv. Marfona), an experiment was carried out as strip plot based on RCB design with 3 replications in 2011 at Isfahan. Treatments included Nitrocara at 4 levels (0: control, 220, 330 and 440 ml.ha-1) as a first factor and Nitroxin+ Phosphate at 4 levels (0+0: control, 20+100, 30+150...

Traditionally, Corydalis tuber has been used for the control of pain including headache, stomach ache, and neuralgia. In the present study, modulation of the Corydalis tuber on glycine-activated ion current in the acutely dissociated periaqueductal gray (PAG) neurons was studied by a nystatin-perforated patch-clamp technique. High concentrations of Corydalis tuber elicited ion current, which wa...

Greenhouse experiment was conducted for four months using Leucaena leucocephala and Pleurotus tuber-regium to determine their bioremediation potentials. Leucaena leucocephala, Pleurotus tuber-regium and Leucaena leucocephala combined with Pleurotus tuber-regium were tested for their ability to improve nutrient (N, P, K, total organic carbon) and reduce heavy metals (Zn, Ni, Pb, Cu) of soil poll...

Apios americana is a wild legume-bearing plant with edible tubers. Domestication of Apios is in progress because of the superior nutritional value and health benefits of the tuber. Objectives of this study were to: (1) characterize physicochemical properties of the Apios tuber starch; and (2) understand differences in starch structures and properties between the mother (seed) and child (progeny...

Tuber pseudoexcavatum, Tuber sinoaestivum, and Tuber indicum are the 3 most important truffles growing in southeast China; however, their cultivation is still inefficient owing to the lack of understanding regarding the composition and function of the bacterial and fungal communities from the soils around the fruit bodies and the ectomycorrhiza of these truffles. The aim of this study was to di...

build, maintain the body's structure and supply energy for vital activities. Protein tends to be the most expensive. The safest, simplest and cheapest source is the non protein nitrogen urea. It has been reported that one hundred grammes of urea are equivalent to 200g of digestible protein provided the remainder of the ration supplies enough readily usable energy (McDonald et al., 1995). The ce...

Potato tuber development has proven to be a valuable model system for studying underground sink organ formation. Research on this topic has led to the identification of many genes involved in this complex process and has aided in the unravelling of the mechanisms underlying starch synthesis. However, less attention has been paid to the biochemical pathways of other important metabolites or to t...
