Abstract
Ushbu maqolada manzarali va mevali daraxtlarda shira harakati hamda uning yog‘och (ksilem) hosil bo‘lishiga ta’siri tahlil qilindi. Tadqiqot natijalari shuni ko‘rsatadiki, shira oqimi daraxtlarning suv bilan ta’minlanganlik darajasi, sug‘orish rejimi va mikroiqlim omillariga bevosita bog‘liq. Shira harakatining o‘zgarishi kambiy faoliyatiga ta’sir etib, yangi ksilem to‘qimalarining hosil bo‘lish jarayonini belgilaydi. Thermal Dissipation Probe (TDP) usuli yordamida shira oqimi va transpiratsiya jarayonlarini baholash mumkinligi aniqlangan. Olingan natijalar daraxtlarning suv talabini aniqlash, sug‘orish tizimini optimallashtirish hamda ularning barqaror o‘sishini ta’minlashda muhim ahamiyatga ega
