College of Education, Samarra University discussed a master dissertation on the phenotypic and chemical response of growing green pepper plants under light stress by the postgraduate student, Mr. Abdul Mohsen Ali Juma.
The dissertation reviewed the effect of light intensity on the vegetative and chemical traits of sweet peppers, as well as detecting changes in secondary compounds using GC-MS under light stress conditions.

The dissertation highlighted that the control factor (µE 55) was superior in most vegetative traits, while the intensity (µE 780) achieved the highest stem length, diameter, and number of stomata in most vegetative traits.
The dissertation also reviewed GC-MS results revealed variations in the number and quality of biologically active secondary compounds, such as vitamin E, sitosterol, and neophytadiene, reflecting their role in enhancing the plant's response to light stress.
