Using the specific primers, it was possible to exclude the Alternaria disease in some leaves with symptoms similar to early blight.Īndersen B, Thrane U (1996) Differentiation of Altemaria infectoria and Alternaria alternata based on morphology, metabolite profiles, and cultural characteristics. Alternaria infectoria occurred in potato and tomato samples occurred at a somewhat lower frequency (13 and 8%, respectively). Alternaria solani was found in 30 and 35% leaves, respectively. It was detected in 50% of tested potato leaves and 41% of tested tomato leaves (alone or in complex). Alternaria alternata (sensu lato) was the most abundant species. All three Alternaria pathogens were present in blighted leaves alone or in complex ( A. Constructed primers were applied for the survey of early blight agents on affected potato and tomato leaves collected in different regions of Russia. The specificity of primers was confirmed by the absence of amplified products after PCR with DNA of Alternaria spp., other potato and tomato pathogenic fungal species and plant DNA. Three species-specific PCR primer sets were designed for Alternaria alternata sensu lato, Alternaria solani and Alternaria infectoria identification. In the present paper a survey of the effects of greenhouse microclimate on crop response in general, and on tomato, pepper and eggplant in particular, was carried out and the findings are presented and discussed.Alternaria species are the causal agents of potato and tomato early blight disease. It is therefore difficult to predict intuitively, the management measures necessary to create optimal crop growing conditions and resource use. ![]() The growth of Solanaceous plants in a greenhouse is a complex process, governed by the interactions between the plant's genetic properties and the environmental conditions, as modified by climate control. ![]() From this point of view, the present paper addresses the information available to be taken into account when it comes for greenhouse climate control. In order to achieve computer control and management of all the principal greenhouse cultivation procedures, such as climate control, irrigation, fruit harvest etc., it is important to know the effects of greenhouse microclimate on crop response. In modern greenhouses, the role of the computer environment management and control is very important. Most of the work done was carried out in greenhouses in Northern countries, while much less has been done in Mediterranean, arid or tropical climates. The great volume of research carried out on tomato does not mean that nothing more left to be investigated. Considerable attention has been paid to pepper during the last few years, while eggplant is less studied. Among Solanaceae, the most researched crop is tomato. Their importance is also obvious when considering the large volume of scientific papers published on relevant subjects. ![]() Solanaceous crops (tomato, pepper and eggplant) constitute about 60% of greenhouse-cultivated areas. ![]()
