It is known that in recent years the attention of many researchers intended to study the effect of global climate change on ecosystems.One of the objects characteristic of the Central Asian republics is wheat.Wheat is the major food crop in all continents of the globe as a source of food for humans,including in Tajikistan.It is known that changes in meteorological parameters of the atmosphere: air temperature,relative humidity and monthly precipitation totals in the complex with the properties of the soil,of course,affect the conditions of growing wheat.In this report will be submitted experimental data about effect of different climatic scenarios on biological and economic productivity of plants,and biochemical quality grain promising varieties of wheat.The analysis of seasonal temperature changes shows that 2007 year is characterized by the fact that the seasonal temperatures somewhat higher than the mid-season,the temperature values over the past decade (in winter 0.920 C,spring and summer at 0.520 C above the mid-season values,and autumn temperatures - 0.170 C less than a mid-season values per decade) during 2008 year is characterized by the fact that winter temperatures at -5.410 C colder than the mid-seasonal temperatures in a decade,spring at 1,450 C and 1,020 C in the summer and fall to 0,20 degrees warmer than the mid-season,the temperature values over the decade, during 2009 and spring temperatures -0.150 C in summer - 0.330 C and fall to -0.030 C colder than the mid-season,the temperature values per decade.In last three years,were experienced low seasonal temperatures in 2009 year due to heavy rainfall.Overall,this year may be considered for the growth and development of wheat favorable.
