  high temperature and high light
Although there were exceptions, particularly in the effect of irradiance on leakiness in Sorghum and Boerhavia, we conclude that conditions favourable to C4 photosynthesis (high temperature and high light) lead to a reduction in leakiness.
      
tenacissima to stress allows for a greater tolerance of water shortage, high temperature and high light intensity, which are typical in these semi-arid environments and accounts for its distinctive opportunistic growth.
      
Moreover, good photosynthetic productivity was also obtained under high temperature and high light intensity conditions (maximum temperature, 46.5°C; 1.737 mmol photons/[m2·s]), when simulating the strong irradiance of the midday summer sun.
      


The diurnal variations of Rs and Tr and their relations to droughtresistance of fruit trees such as date, apple, grape and peach treesgrowing in the pots or fields were studied under the suitable orunsuitable weather conditions. It suggested that the diurnal variationsof Rs and Tr under the suitable temperature light intensity andrelative humidity showed a single-peak curve i.e. Tr, reached amaximal value and Rs a minimal one when the temperature andlight intensity reached the peak values at midday. The diurnalvariations...

The diurnal variations of Rs and Tr and their relations to droughtresistance of fruit trees such as date, apple, grape and peach treesgrowing in the pots or fields were studied under the suitable orunsuitable weather conditions. It suggested that the diurnal variationsof Rs and Tr under the suitable temperature light intensity andrelative humidity showed a single-peak curve i.e. Tr, reached amaximal value and Rs a minimal one when the temperature andlight intensity reached the peak values at midday. The diurnalvariations under the high temperature, high light intensity and lowrelative humidity at midday showed a double-peak curve, the first peakof which occured at 10 o'clock and the second one at 14 o'clock,and the stomata became small and Tr reduced remarkably at midday.If the high temperature and high light intensity lasted until theafternoon, Tr and Rs could not recover in the afternoon and therewas no second peak. There were no significant differences of Tr and Rs among thedifferent drought-resistant fruit trees under the suitable weatherconditions, but under the high temperature, high light intesity andlow relative humidity, the date, the highest drought-resistant plant,had the lowest Tr and the highest Rs at midday among the date, apple,grape and peach trees. It indicated that though the drought-resistantspecies had the high Tr under the suitable conditions, Tr was quicklyreduced when the plants were turned to the unsuitable condition. An analysis of regression showed that relationships betweentemperature or relative humidity and Tr or Rs and between lightintensity and Rs were all second-degree trinomial except that therelationship between PFD and Tr was deformed hyperbolically. By using stepwise regression it was found that the temperature and light werethe main factors affecting Tr and Rs respectively before 9 o'clock,and the low relative humidity was the main factor affecting both Trand Rs during 9-12 o'clock, while the temperature and light hadless effects because they had almost reached the highest values then.After 12 o'clock the light intensity which gradually weakened becamethe main factor which caused the increase of Rs and then the increaseof Rs caused the decrease of Tr.

本文研究了不同天气条件下,盆栽及大田生长的苹果、桃、葡萄和枣等果树的蒸腾强度(Tr)、气孔扩散阻力(Rs)的日变化以及这种日变化与抗旱性的关系。证明在温度、光照和湿度适宜的条件下,各果树的Tr、Rs日变化均为单峰曲线,Tr的高峰值、Rs的低峰值正处在温度和光照较高与湿度最适的时候;当中午温度和光照过高,湿度过低吋,Tr、Rs日变化呈双峰曲线,第一峰值在10时左右,第二峰值在14时左右,中午气孔关閉,Tr降低,若从中午到下午持续高温,Tr在下午一直下降,不会出现第二峰值。在适宜条件下,抗旱性较强的枣树,其Tr、Rs与其它树种并无差异,但在中午高温干旱条件下,Tr明显低于和Rs明显高于其它树种。因此,干旱逆境下Rs迅速增大、Tr迅速减小是枣树的重要抗旱特点。一元回归表明:温度、湿度或光照与Tr或Rs的关系为二次三项式(仅光照与Tr的关系除外,为变形双曲线)。逐步回归和通径分析得出,9时前,影响Rs的主导因子是光照,影响Tr的是温度;从10时到12时,大气相对湿度成为影响Rs、Tr的主导因子;在12时后,光照再次成为影响Rs的主导因子,而Tr的下降主要由于Rs的增加引起的。

Beau seedlings stressed by low temperature (4℃±1℃ ) in darkness for 12 h were treated with middle temperature and low light intensity (15℃±1℃, 72 μmol· m-2·s-1 ), high temperature and high light intensity (20℃±3℃, 224 - 340 μmol· m-2·s-1 ), and low temperature and low light intensity (4℃±1℃, 72 μmol· m-2· s-2), respectively. In the chilled seedlings treated with low temperature and low light intensity,and high temperature and high light intensity,the contents of MDA increased...

Beau seedlings stressed by low temperature (4℃±1℃ ) in darkness for 12 h were treated with middle temperature and low light intensity (15℃±1℃, 72 μmol· m-2·s-1 ), high temperature and high light intensity (20℃±3℃, 224 - 340 μmol· m-2·s-1 ), and low temperature and low light intensity (4℃±1℃, 72 μmol· m-2· s-2), respectively. In the chilled seedlings treated with low temperature and low light intensity,and high temperature and high light intensity,the contents of MDA increased continuously during two days,the lower activities of SOD,POD and CAT were keeped,the electrolyte leakage of plasmalemma reached their maxima at the first day and then decreased slowly. But in ones treated with middle temperature and low light intensity,the content of MDA increased less, the activities of SOD, POD and CAT recovered more rapidly, the electrolyte leakage of plasmalemma approached normal value after two days, the chilled seedlings restored more quickly. Use of the chilling protective agent mefluidide could reduce chilling injury of beau seedlings and accelerated them restoration.

将暗中(4±1℃)低温胁迫12h的菜豆幼苗分别置于中温弱光(15℃±1℃,72μmol·m-2·s-1)、高温强光(20℃±3℃,224-340μmol·m-2·s-1)、低温弱光(4℃±1℃,72μmol·m-2·s-1)3种条件下进行处理,结果发现2d中低温弱光和高温强光下菜豆幼苗的MDA含量不断上升,其SOD、POD、CAT酶活力也维持在较低水平.质膜外渗电导率在处理第1天时上升到最大,之后缓慢下降。而中温弱光条件下的菜豆幼苗MDA含量上升较少,SOD、POD、CAT酶活力恢复较快,质膜外渗电导率在2d后即接近正常值,菜豆幼苗冷害恢复较迅速。施用低温保护剂Mefluidide可减轻菜豆幼苗冷伤害并加快其恢复。

There was significant influence of soil water content on water potentials and photosynthesis in ginger leaves.Soil water stress decreased the light saturation point of photosynthesis,photosynthetic rate,diurnal changes of photosynthesis and enhanced the midday depression of photosynthesis.Under the circumstances of high temperature and high light,soil water stess decreased the activities of protecteive enzymes SOD,POD and CAT.
