Changes in soluble and insoluble carbohydrates of safflower (Carthamus tinctorius L.) influenced by supplemental irrigation and super absorbent polymer

摘要: The present investigation studied the effects of supplemental irrigation, application Super Absorbent Polymer (SAP) on seed yield, and physiological characteristics relevant to water stress in leaves roots safflower. Supplemental irrigation was implemented at 4 levels including dry-farming; late vegetative, flowering, filling seeds phases as main factors. absorbent polymer two (Control 200kg/hectares) 6 safflower varieties were used winter cultivation factorial form sub-factors. results indicated that can prevent a reduction yield by improving parameters like soluble insoluble carbohydrates. At flowering stage, increased an average 35% compared with dry-farming, thereby producing maximum rate both test years. carbohydrate reduced under influence but carbohydrates concentration increased. Leaves varied similarly respect any parameters, their concentrations different. Employing SAP affect all lead toward drought stress. It is suggested together be for its phase order reduce loss increase dry-farmed cultivations.
