17-Rasm. O’simliklarni o’stiruvchi suniy fitogormonlar
Urug’larning normal o’sishini ta’minlash uchun Petri kosachalarini harorati 25-28°C bo’lgan, yorug’lik tushmaydigan qorong’i xonalarga yoki termostatga qo’yiladi. Bir qaftadan keyin tajribaga olingan urug’larning ildiz o’sishi lineyka yoki millimetrli qog’oz bilan o’lchanadi va olingan ma’lumotlar 22-jadvalga yozib olinadi. Tajribadan olingan natijalar, talabalar o’rtasida muhokama qilinadi va ulardan tegishli xulosalar chiqariladi.
