Changes in the microclimate and transpiration of reedbeds on the shores of Lake Balaton, some still standing in water and some from which the water has receded, were examined in Keszthely Bay during the 2003 vegetation cycle, after canopy closure. Microclimate data were recorded using combined sensors connected to a data-collector. Ten-minute means calculated from data recorded every two seconds were used as the basis of comparison. Transpiration was quantified using the shoot mass loss method. The leaf area index of reeds growing on dry areas was greater than that of plants rooted in the lake. This difference was moderate at first, but increased greatly during the vegetative phase, and could be attributed primarily to differences in plant density and leaf size, and to the effect of waves. Among the components of the microclimate, the humiditywithin the stand was 8-20% greater for plants growing in water, irrespective of the weather and the development stage. The daily mean air temperature was lower in the dry stand, and exhibited considerable daily fluctuations. The mean daily sum of transpiration, averaged over three sample days, was 16.5% lower in the dry stand. The plot of daily changes in transpiration exhibited two peaks for the dry stand and one for the wet stand.

Strong drought tolerance is an important objective in breeding new wheat varieties. We compared the drought tolerance of land races and modern varieties of various spring wheat forms. 13C discrimination (CID) indicated how significantly the tested wheat varieties were inclined to drought tolerance. CID is a trait related to stomatal closure and consequently an important component of the tolerance to drought. Samples were grown in České Budĕjovice (CZ), from 2009 to 2012. Twenty-three varieties, comprising einkorn, emmer, spelt, land races and control variety of bread wheat were grown and tested. Results have shown some varieties achieved low CID values (which meant they were more inclined to the drought tolerance). There were emmer and spelt varieties among them in particular. The spelt varieties which were inclined to the drought tolerance most significantly were — Triticum spelta No. 8930, Tabor 23 and Tabor 22. The emmer varieties called May-Emmer and Weisser Sommer were also inclined to drought tolerance significantly. By contrast, the intermediate forms, the modern (control) varieties of bread wheat, and einkorn varieties, were expected to be less tolerant to drought as well. Some of the wheat land races (the spelt and the emmer in particular) reached low values of CID. Therefore, they can play the role of drought tolerance donors in the wheat breeding programmes.
