استجابة خزعات براعم صنفين من البطاطا لتراكيز مختلفة من منظمات النمو

Abstract EN

This research was carried out to study the response of different sprout tip lengths (1, 2 and 3 mm) of two potato cultivars (Chandramokh and Marfona) to different concentrations of growth regulators (NAA: 0, 0.1, 0.3, 0.5 mgl-1 and BAP: 0, 0.2, 0.4 mgl-1) in the laboratory of tissue culture (Isfahan University of Technology/Iran).

The results showed an effect of sprout tip length (2 mm) cultivated on MS medium added with NAA and BAP (0.3, 0.4 and 0.5, 0.2 mgl-1), respectively for Chandramokh and 3mm cultivated on (0.5, 0 mgl-1) for Marfona on the length of plants.

The number of leaves increased when 2mm sprout tip of Chandramokh grown on (0.1, 0 mgl-1) added to MS medium, and when 3mm sprout tip of Marfona grown on (0.3, 0 mgl-1).

Higher number of Chandramokh roots were noticed by using 2mm sprout tip and (0.5, 0.2), (0.5, 0) and (0.1, 0) mgl-1, whereas, (0.1, 0 mgl-1) gave longer roots.

In Marfona, higher number and longer roots were found by using 3mm sprout tip and (0.3, 0) and (0.5, 0) mgl-1.

These results were very important for other studies because of the good effect of NAA on the growth of two potato cultivar plants
