AYRIM FITOGARMONLARNING YANGI XOSILALARI SINTEZI VA ULARNING O'SIMLIKLAR O'SISH RIVOJLANISHIGA TA'SIRI

Аннотация

O’zbekiston Respublikasini yanada rivojlantirish bo‘yicha harakatlar strategiyasida «Ilmiy-tadqiqot va innovatsiya faoliyatini rag‘batlantirish, ilmiy va innovatsiya yutuqlarini amaliyotga joriy etishning samarali mexanizmlarini yaratish» bo‘yicha alohida vazifalar belgilab berilgan. Shunga ko‘ra mamlakatimizda muhim strategik ahamiyatga ega bo‘lgan o’simlik turlari uchun stressga nisbatan chidamliligini tabiiy fiziologik moddalar asosida, fitogarmonlarning galogenli xosilalari sintez qilinmoqda, ularning tasir etish kuchini oshirish va ularning fizik- kimyoviy xossalari atroflicha o’rganilyapti Kalit so’zlar: Fitogarmon, YuSSX, IQ, biologik faollik, Xramotagrafiya, Indol 3-Moy kislota Asosiy qism Indol Moy kislota o’simliklar unish va o’sishini tezlashtiradigan modda hisoblanadi, uni avval geterofit auxin deb nomlashgan(1). Qutbli erituvchilarda erib rangsiz eritmalar hosil qiladigan bu eritmaning juda oz miqdordagi eritmasidan foydalaniladi va yaxshi natijalarga erishish mumkin bo’ladi(2). Bunga uning tuzilishini korib chiqishimiz mumkin 1 ta benzol va 5 halqalardan tuzilgan azotli getrosiklik organik modda hisoblanadi. Indol moy kislota Indol 3 moy kislotasi (IBA-3)— auxinlar qatoriga kiruvchi fitogormon hisoblanadi va uning biosintezi nafaqat yuqori o‘simliklarda, balki bir qator tuproq mikroorganizmlari tomonidan, xususan, o‘sish rag‘batlantiruvchi rizobakteriyalar tomonidan ham amalga oshiriladi(4) Indol moy kislota (english– Indole 3- butyric acid, IBA-3) o’simliklarda tabiiy ravishta mavjud bo’lgan lekin juda ham kam miqdordagi massa bilan uchraydigan va ularning o’sib rivojlanishi uchun ma’sul bo’lgan o’simliklar garmoni hisoblanadi. IMK molekular formulasi C H NO bo’gan oq rangli kristal tuzilishga ega bo’lgan kukun 12 13 2 hisoblanadi(5). https://scientific-jl.com/new 11 44 44 Volume–78_Issue-2_June-2025 JOURNAL OF NEW CENTURY INNOVATIONS Olingan natijalar taxlili Olingan natijalardan korinib turibdiki, IMK ning bromli hosilasi uning o’zidan Antibakterial hossasi va zamburug’larga qarshi kurashishi kabi biologik ko’rsatkichlari miqdori oshganligi bilan ahamyatlidir Olingan zamonatiy fizik kimyoviy natijalarga ko’ra ajratib olingan yangi moddaning tozalik korsatgichi 81% ga teng ekan. 1-rasm. IMK-3 Br IQ spektorlari https://scientific-jl.com/new 11 44 55 Volume–78_Issue-2_June-2025 JOURNAL OF NEW CENTURY INNOVATIONS Uni adabiyotlardan ko’rishimiz mumkinki 690-515 sm-1 oraliqda nur yutib pick berishi malum qilingan, bizning spektrlarimizdan ham ko’rinib turiganidek, umumiy olinadigan barmoq izi sohasini ichida namoyon bo’ladi, ya’ni 590 sm-1. Kislorod va vodorod (O-H) bog’ qisman vodorod tomonga siljigan hisoblanadi. Uglerod va vodorod (C-H) spektrlarida deyarli katta o’zgarish ko’rinmagan, uglerod va kislorod (C=O) bog’ da ham sezilarli o’zgarish kuzatilmagan (6,7). Indol 3-moy kislota bilan Brom hosilasidan ham deyarli shunga o’xshash natijani kuzatishimiz mumkin bo’ladi. Uglerod va Brom (C-Br) spektorlari yutilishi 690 sm-1 ga to’g’ri keladi, demak IMK ning bromli hosilasi ham hosil bo’ldi deb hisoblash mumkin bo’ladi. Xulosa Indol 3-moy kislotaning xossalari va yangi ajratib olingan Indol moy 3-moy 5- brom hosilasi zamonaviy fizik-kimyoviy usullar bilan tekshirildi Kelajakda ulardan xalq xo’jaligi va qishloq xo’jaligida foydalanish istiqbollarini o’rganish maqsadida ularning biologik faolliklari o’rganilib taxlil qilindi Foydalanilgan adabiyotlar ro’yxati 1.
