Abstract
Relation of temperature to the salt injury in paddy rice plants (Variety Norin No. 8) was investigated. 1) In a green house (the high temp. plot.) the salt injury was observed to be severer than in the open air (the natural temp. plot.). 2) Air temperatute was 27.2°C (average at 10.00 a. m.) in the natural temperature plot and 30.7°C in the high temperature plot, and relative humidity was 73.4 % and 63.5 % respectively. 3) Vigorous transpiration by the high temperature and the low humidity under the green house promoted the intake of water and salt by the plant, and consequently it seemed that the salt injury became severe.
