Plant response of rice (Oryza sativa L.) var. LP-7 to the application of different NaCl levels. II. Inorganic and organic ions
Main Article Content
Abstract
controlled conditions of temperature, humidity and light, with
the aim of determining N+, K+ and total soluble sugar contents
in rice (Oryza sativa L.) plants from LP-7 variety exposed to
different NaCl levels. Plants developed in a hydroponic growth
chamber. Evaluations were recorded at the beginning of the
experiment, seven and 14 days after applying treatments and
seven days after its recovery in a nutrient solution without
NaCl. Evaluations consisted of determining Na+, K+ and total
soluble sugar contents. The analysis of those variables
showed differences concerning ion accumulation in all plant
organs, and the tested variety behaved as a Na+ including one
in its root system, which makes it sensitive to high NaCl
concentrations.
