Effects of polyethylene glycol on proline levels in two sugar beet cultivars
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 9
Abstract
To evaluate the physiological traits, proline and two Jolge and Rasoul beet varieties under drought stress experiment in a randomized complete block Rasoul on hydroponic culture at 5 levels (0, -1.4, -2.9, -4.18 and -7.11 MPa), respectively, of the levels (0, 98, 148, 197 and 322 grams per liter) polyethylene glycol 6000 and 3 replications was conducted in 2012, in Ardebil. Proline in two periods of 10 days and 20 days after stress was measured and compared to that proline leaves in both cultivars and both figure to increase significantly and increases during stress, proline leaves the gain reaches a figure of Jolge Rasoul more than the increase in the maximum concentration of proline was 322. Increase of proline in osmotic potential to absorb and hold water for the plant, along with increasing protein to prevent protein decomposition of and power plant can be a good indicator for selecting cultivars are resistant to drought. Proline in Jolge variety with maximum tension adjustment is more than a Rasoul figure. Resulting in increased resistance to environmental stress and are suitable for growing in water scarce regions.
