砂丘植物の研究(第4報) : ネコノシタ葉温に及ぼす風の影響

The relationship between the leaf temperature of Wedelia prostrata Hemsl and wind velocity was investigated by comparing the shoot and stolon stem. The stolon stem leaf temperature，r gardless of wind velocity，was 6-7℃ lower than the air temperature in the day time. On the other hand，the shoot stem leaf temperature on a low wind day was higher，and on a high wind day was lower，than the air temperature. The difference between the leaf and air temperature was 1-2℃. The relationship between the air (x) and leaf (y) temperature is as follows. Low wind day stolon stem y=0.628x+9.01, r=0.936*** shoot stem y=1.198x-5.28，r=0.985*** High wind day stolon stem y=0.610x+9.65，r=0.963*** shoot stem y=0.667x+8.55，r=0.905***
