The fertility in sweet cherry is determined by a gametophytic self-incompatibility system, controlled by a multi-allelic S locus who prevents self-pollination. The fertilization is controlled by the interaction of an S allele specific ribonuclease (S-RNase) in the style with a pollen S specific F-box protein gene (SFB). Knowledge about the S genotype of sweet cherries is very important for cherry growers and breeders. In the last years molecular markers have been developed to distinguish the...

The influence of Effective Microorganisms and number of buds per cane in viticulture on chemical composition in fruitsAlicja Auriga, Ireneusz Ochmian, Jacek Wróbel & Jan Oszmianski
As a result of climate warming, wine-growing zones have moved to the north, where conditions exist may result in poor fruit quality. Fruits may develop significant amounts of tannin compounds, which are not acceptable to all consumers. The aim of this study was to demonstrate the influence of selected factors on the quality and content of polyphenols in grapevine fruits. The differentiating factors were as follows: two grapevine cultivars, varied number of buds per cane,...
Dioscorea nipponica Makino is an optimal candidate to develop the diosgenin industry in North China. Given the large fluctuations in soil water availability induced by global climate change, information on drought tolerance of this species is urgently needed. Thus, seedlings of three provenances, selected from Manghe, Pangquangou nd Luyashan Nature Reserves in Shanxi Province, were exposed to 70%-85%, 55%-60%, 40%-45% and 20%-35% of water holding capacity, representing normal-watered, light drought stress, moderate drought stress and...

Fruits of five apple cultivars were treated using 1-methylcyclopropene (1-MCP or SmartFreshTM) after cropping and were stored at normal atmosphere 2 ± 0.5 °C, 90 ± 5% relative humidity (RH) and 20.9 kPa O2 + <0.5 kPa CO2. Fruit firmness was assessed at three periods: 7 d after storing, 120 d after storing and 30 d after the second assessment and storing at room temperature. Contents of K in all of the cultivars and in...

Can plant bio-regulators minimize crop productivity losses caused by drought, heat and salinity stress? An integrated reviewRatna Kumar Pasala, M. I. R. Khan, Minhas P.S., Farooq M.A., Sultana R, T. S. Per, Deokate P.P., Khan N.A. & J. Rane
Plant bio-regulators (PBRs), are biochemical compounds which stimulate plant growth and productivity when applied, even in small quantities at appropriate plant growth stages. These are being extensively used in agriculture to enhance the productivity particularly in horticultural crops but are not as prevalent in field crops. Their central role in plant growth and development is through nutrient allocation and source-sink transitions while some of the PBRs stimulate hormones related to abiotic stress tolerance. Since climate...

Many phosphine-emitting products are used globally to control insect pests in dried vegetables, grains and pulses. However, variation in phosphide formulations is associated with colour change in many pulses. This study evaluated the effect of fumigation using Mg3P2 containing ammonium carbamate; AlP containing no ammonium carbamate and pure ammonium carbamate on colour of diferrent pulses. Different pulses showed different reactions towards fumigation with phosphine. A distinctly darker discolouration was observed in broad beans and lentils...

Computer-aid molecular docking is a simulative process that receptors and ligands recognize each other through energy matching and geometric matching. It is widely used in bioactive compounds simulative screening and preliminary exploring the bioactivity and toxicity of molecular, which plays important guiding role in toxicity and bioactivity study of molecular entities. In our study, we used the computer-aid molecular docking software-discovery studio 3.1 client to test the mechanism of aflatoxins such as aflatoxin B1, B2,...
