Abstract

This study was carried out to investigate the effect of water limit through the control of water content within rhizosphere on the leaf temperature changes of hydroponically grown tomato plant as a water stress index. As water contents treated were 30, 35, 40, 45, 50±5%, the leaf temperature was lower 0.5 to 1.1 (cid:59282) , but pericarp temperature was higher 1.8 (cid:59282)(cid:71) than air temperature in August. On second day of water limit, leaf temperature was highest at 3 pm and higher 2.8 (cid:59282)(cid:71) than air temperature. After about 60 days of water limit, leaf temperature as affected by below 40% water content was similar with or higher than air temperature. Therefore these results could be used as a water stress index, however, it would be considered that more investigation and analysis on leaf temperature changes by time passes were needed.

根际限水对番茄叶片温度变化的影响

本研究通过控制根际水分作为水分胁迫指标，探讨了限水对水培番茄叶片温度变化的影响。当含水量为30、35、40、45、50±5%时，叶片温度比8月份气温低0.5 ~ 1.1 (cid:59282)，果皮温度比8月份气温高1.8 (cid:59282)(cid:71)。限水第二天下午3时叶温最高，比气温高2.8 (cid:59282)(cid:71)。限水60 d左右，含水量低于40%对叶片温度的影响与空气温度相近或高于空气温度。因此，这些结果可以作为水分胁迫的指标，但需要对叶温随时间的变化进行更多的调查和分析。
