ABSTRACT
In this investigation, the seeds of A. precatorius L. were studied for their chlorophyll contents which were pretreated with IAA, Brassinolide, Thiourea and Potassium nitrate before germination. The highest chlorophyll contents were found to be in IAA treated seeds followed by those treated with brassinolide, thiourea and potassium nitrate. The respective amount of chlorophyll under these treatments was found to be 4.91, 4.79, 4.66 and 4.33 mg-g FW ¿¹ under IAA (100 ppm), brassinolide (50 ppm), thiourea (50 ppm) and potassium nitrate (50 ppm) compared to the control seedlings which were estimated to have 4.26 mg-g FW ¿¹ of chlorophyll. The mentioned results concluded that the primary productivity of this chosen plant increases with higher dozes of IAA as compared to controlled seedlings as well as other used factors.
