Abstract
Mazkur maqolada Phaseolus aureus L. (mosh) ning 12 ta nav va namunalarida transpiratsiya jadalligi fenofazalar kesimida (chinbarglash, g‘unchalash, gullash, dukkalash, pishish) tahlil qilindi. Tadqiqotning maqsadi — transpiratsiya jadalligida fazalararo hamda genotiplararo farqlarni aniqlash va ularning barqarorlik darajasini statistik ko‘rsatkichlar orqali baholashdan iborat. Transpiratsiya jadalligi g/m²·soat birligida qayd etilib, har bir faza bo‘yicha x̄±SE, S va V% ko‘rsatkichlari asosida tavsiflandi [1]. Natijalarga ko‘ra, 12 genotipning umumiy fonida transpiratsiya o‘rtacha qiymati g‘unchalash bosqichida eng yuqori (158,65 g/m²·soat), undan keyin gullash (133,73 g/m²·soat) fazasida kuzatildi; chinbarg bosqichida esa eng past daraja qayd etildi (72,15 g/m²·soat) [1]. Fazalar bo‘yicha ekstremal qiymatlar keskin tafovut qildi: g‘unchalashda 53,08–308,13; gullashda 57,75–281,20; pishishda 24,11–278,11 g/m²·soat oralig‘ida o‘zgarib, transpiratsiya rejimi genotipga kuchli bog‘liqligini tasdiqladi [1]. Barcha fazalar bo‘yicha o‘rtacha transpiratsiya eng yuqori NC-17376 (Xitoy)da, eng past NC-33641 (Afg‘oniston-2013)da qayd etildi; barqarorlik jihatidan NC-33647 (Tayvan-2013) (V% past), o‘zgaruvchanlik jihatidan NC-32061 (Filippin-2013) (V% yuqori) ajralib turdi [1]. Olingan natijalar mosh genotiplarini suv rejimi bo‘yicha skrining qilish va seleksiyada fiziologik mezon sifatida transpiratsiya ko‘rsatkichlaridan foydalanish imkonini beradi.
