Studies on Nutrient Absorption of Rice Plants in Taiwan (Part 2) Nutrient Absorption by Japonica and Indica Varieties of Rice in Relation to Temperature

Abstract

Agronomic characters and nutrient absorption of a Japonica veriety, Taichung no. 65 and an Indica variety, Peh-mi-fen under different temperature conditions were investigated. Pot experiments were made in two glass-houses with different tempera-tures, one glass-house with closed and the other with opened windows The former had temparatures 2.4oC higher than the latter on the average for the growing period. 繼第一報以蓬萊種水稻，臺中65號觀察溫度對養分吸收之影響後，本年度另增在來種水稻，白米粉一種以比較兩品種水稻在不同溫度處理下之養分吸收狀況和生育性狀，結果如下。試驗仍如前報於兩玻璃室內進行，其一係玻璃窗開啟，另一則關閉以做為比較上之高低溫區。如此水稻生育期間，高溫區平均溫度可高於低溫區約2.4℃。
