Capital market, subsidies, agricultural and rural developments in the Republic of Macedonia

The undeveloped rural capital market in the Republic of Macedonia is constrained by an urban–rural development gap with limited capacities for rural development and imperfections in the rural capital market. Among the most striking hindrances are the illegal status of a large share of agricultural buildings and other real estate in rural areas, particularly, on the individual family farms that prevail in the...

Effect of 1-methylcyclopropene, potassium permanganate and packaging on quality of banana

The experiment consisted of ten treatments some of which are: teff straw, banana leaf, perforated and non-perforated polyethylene bag. KMnO4 or 1-MCP was found in polyethylene (perforated or non-perforated) and 1-MCP treated fruits were kept in open air as control. Banana fruits were assessed for important physical and chemical quality. Banana fruits treated with 1-MCP showed better fruit quality. Perforated...

Harvest, export and economic status of freshwater crayfish (Astacus leptodactylus Esch.1823) in Turkey

This study was carried out on the export and economic status of freshwater crayfish (Astacus leptodactylusEsch. 1823) in Turkey. Due to the fact that there is a very low domestic consumption of freshwater crayfish in the country, Turkey had been the largest provider of A. leptodactylus to Western Europe from 1970 until 1986. The peak production of the country was attained in the early 1980s, with over 5.000...

High temperature induced fertility transition and anther carbohydrate metabolism modification in a canola recessive genic male sterile line

High temperature stress is an important abiotic stress during plant growth and development that can damage canola male reproductive organ development. In this present study, we characterized a canola genic male sterile line that its fertility can be restored after high temperature induction with heterozygous but not homozygous condition. Anther length and weight was elongated and increased 2 and 5.7 times at 9 days...

Genetic and postharvest factors affecting macadamia kernel quality

Macadamia (Macadamia integrifolia, Macadamia tetraphylla and hybrids) is cultivated in regions of Eastern Australia. Genotype and geographical location, a factor seldom studied, may influence kernel quality. Macadamias from three cultivars were harvested from three commercial plantations, each in a different region of Eastern Australia over three consecutive seasons. Kernel quality was assessed by...

Extracellular lipase of the antarctic bacterial isolate, Pseudomonas sp. INK1 as a potential tool for improving the flavor quality of dairy products

An antarctic bacterial isolate displayed extracellular lipolytic activity. Based on the 16S rRNA sequence analysis, the strain was named Pseudomonas sp. INK1. The INK1 lipase was secreted into the production medium during transition to the stationary phase. The enzyme reached the apparent maximal activity at pH 8 to 9, with optimal activity at 50°C. The enzyme was active against a wide range of fatty acid...

Growth and physiological responses of five Malus species to the pH of hydroponic solutions

We characterized the growth and physiological responses of five wild Malus species indigenous to China to acid and alkaline abiotic stresses. At the six-leaf stage, seedlings of Malus sieversii, Malus prunifolia, Malus robusta, Malus mandshurica and Malus hupehensis were transferred to hydroponic systems in which the solution pH was 5.5, 7.0 or 8.5. Fresh and dry weights,...

Physiological traits, yields and nitrogen translocation of ratoon rice in response to different cultivations and planting periods

Rice (Oryza sativa L.) ratooning is the production of a second rice crop from the stubble left after the main crop harvest. Its growth and development are affected by the environment factors and the growth condition of the main crop. The objectives of this study were to evaluate the effects of different cultivations (DS: direct-seeding, ST: seedling-throwing, TP: transplanting) and planting periods of the main crop on...

Effect of nitrogen doses on the chlorophyll concentration, yield and protein content of different genotype maize hybrids in Hungary

The chlorophyll (Chl) concentration of maize was compared to its grain yield and protein content in six different N treatments (0, 30, 60, 90, 120 and 150 kg N ha-1) in a multifactorial field experiment with four replications and a split plot design in Eastern Hungary (47°33’ N, 21°26’ E, 111 m asl) in two years (2009 and 2010). Nitrogen fertilisation significantly (p < 0.001) increased Chl...

Allelopathic influence of leek (Allium porrum) seeds on germination and radical growth of flue-cured tobacco of different cultivars

Leeks (Allium porrum L.) are increasingly included in the rotation or inter-planting with tobacco in many provinces of China and worldwide. Therefore, we examined the possible allelopathic potential of leek seeds on the germination, seedling emergence and root elongation of flue-cured tobacco of different cultivars. The effects of imbibed leek seeds, their aqueous leachates and extracts of the seed on the...
