摘要
Peanut (Arachis hypogaea L., var. TMV-2) plants were raised in sand cultures salinized with sodium chloride at 0.4% on air dry weight basis. Phosphate was sprayed to the drip point, once daily for five days from 20th to 25th day and from 30th to 35th day. Shoot apices and mature leaves were harvested for nucleic acid analyses at 30th and 40th day, receiving one and two sets of sprays respectively. Salinity decreased RNA and DNA levels which were partially restored by foliar application of phosphate. © 1979 Martinus Nijhoff Publishers.
