Growth And Development of Eriobotrya Japonica (Thunb.) Lindl. In The Conditions of Surkhandarya Region

Abstract

Great attention is paid in our country to the issues of full provision of the population with food products, full satisfaction of consumer demand at the expense of fruits and grapes grown in the country, as well as increasing the export potential. The southern regions of the Republic of Uzbekistan have all the conditions for the development of horticulture, where it is possible to grow almost all types of fruit crops [1]. The geographical location of our republic has a strong impact on the climate. The distribution of solar radiation, air temperature and humidity, and precipitation varies by region, which has a strong impact on plant growth and development. Especially since fruit crops are perennials, they are constantly affected by external conditions not only during the growing season, but also throughout the year. The average temperature in Surkhandarya region does not fall below 0 degrees in winter. The average absolute minimum temperature is -12-15º, and the probability of damage to fruit crops in winter is very low. Summers are characterized by high temperatures (above 50°C) and low humidity. Under these conditions, heat and drought resistance are the most important biological properties. Adequate light and heat factors, as well as the length of the growing season, allow the fruit crop to grow and develop rapidly and produce high yields. The availability of varieties that ripen at different times allows to provide the population with fresh fruits throughout the year
