Effect of pix regulator on morphophysiologycal responses of cotton (Gossypium hirsutum L.) to drought tress
In today, the use of growth regulators not only cause growth improvement and increase product of cotton but also rise resistant of this plant to environmental stresses. In this research the effect of drought stress and also drought with pix in different concentrations (0. 5, 1. 5 and 2. 5 L/ha) were...

| description | In today, the use of growth regulators not only cause growth improvement and increase product of cotton but also rise resistant of this plant to environmental stresses. In this research the effect of drought stress and also drought with pix in different concentrations (0. 5, 1. 5 and 2. 5 L/ha) were used in form spray and control (irrigation) in reproductive phase on growth factors, amounts of chl a and b, soluble sugars and starch under condition of pots were evaluated. The results of this research showed that application of pix because decrease stems length in comparison to drought treatment and control. Other growth factors such as root length, number of internodes and bolls, dry and fresh weight of shoot in treatments of drought with pix different contents did not change significantly. Number of leaves also in drought with 1.5L/ha concentration of pix treatment decreased significantly in comparison to drought treatment Amounts of chl a and b did not affect under different treatments. On the other hand the most of amounts of soluble sugars and starch in leaves were observed alone in control and in plants root under drought treatment. In between other treatments these changes were not significant. |
