Abstract
Ushbu maqolada mikroelementlarning tritikale navlari barglaridagi SPAD indeksiga ta’siri o‘rganilgan. Tadqiqot davomida rux va selen mikroelementlar bilan ishlov berilgan tritikale navlarida barglarning xlorofill miqdorini ifodalovchi SPAD ko‘rsatkichlari aniqlanib, navlar o‘rtasidagi farqlar tahlil qilindi. Olingan natijalar rux mikroelementi qo‘llanilishi fotosintetik apparat faoliyatini yaxshilashi, barglarda xlorofill miqdorining ortishiga hamda o‘simliklarning o‘sishi va rivojlanishiga ijobiy ta’sir ko‘rsatishini namoyon etdi. Tadqiqot natijalari rux qo‘llangan tritikalening Svat navida eng yuqori 59,4 birlikni namoyon qildi. Shuning uchun yetishtirishda mikroelementlardan samarali foydalanish, hosildorlik va abiotik stress omillariga chidamlilikni oshirish bo‘yicha ilmiy-amaliy tavsiyalar ishlab chiqishda muhim ahamiyat kasb etadi.References
