Abstract
A hydroponic experiment was conducted to investigate the influence of foliar spraying of 0.4%phosphate fertilizer(P)on the physiological parameters,Cd accumulation and subcellular distribution characteristics in energy crop Ricinus communis with different Cd doses(50,100,150μmol·L-1).The results showed that P spraying increases plant dry mass by 23.2%-61.5%,31.2%-68.3% and 14.7%-23.6%in the roots,stems and leaves,respectively,and the chlorphyll a,chlorphyll b and carotenoid contents were increased by 6.8%-78.0%,10.1%-84.1% and 30.0%-52.1%,respectively.Foliar spraying of P significantly increased Cd concentration in the roots by 25.0%-59.6%,but Cd contents in shoots and leaves showed no significant difference.The proportions of Cd in the cell wall increased,while that in cell organelle decreased.It is supposed that P addition can strengthen cell wall binding,so as to limit Cd translocation and reduce its physiological toxicity in plants.
