The library of the Czech historian Tomaš Pešina of Čechorod who lived in the time after the White Mountain is nowadays part of the family library of the Wallensteins which is housed at the castle in Mnichovo Hradiště. This article focuses on the series of chronicles coming from the estate of Pešina and created around the mid 14th century. The codex contains both copies of national chronicles (Chronicle by Bartošek of Drahonice, Chronicle by Přibik Pulkava of Radonin and Old Czech Annals) and chronicles of the Mladá Boleslav Town and Žatec Town.

The basic slow Idnetics and spectral properties of the chlorophyll fluorescence temperature curve (FTC) under low actinic radíation excitation (s 2 W m"2) were measured in primary barley leaves of shade-grown plants. In contrast to the usual Fo temperature dependence, two distinct regions and two maxima of FTC were documented upon a linear heating regime. The fírst maximum situated between 49.5 and 51 °C was less sensitive, whereas Ihe position of the second maximum (between 53 and 63 “C) was strongly dependent on the heating rate. The spectral resolution of the fluorescence emission suggested a presence of photosystem (PS) 1 emission in the FTC at 436 nm excitation and an efíect of partial light-harvesting complex LHCII disconnection from the PS 2 complex at 480 nm excitation. A new fluorescence emission around 700 nm appeared upon heating. The excitation spectra in the 400 nm to 500 nm region for the 685 nm fluorescence emission wavelength indicated that only one emission form was responsible for both of the FTC bands. The 77 K fluorescence spectra at increasing, maximal and decreasing parts of Ihe second FTC band were measured using the triggering expeiiments wilh an incubation temperature of 58 oC. A disconnection of LHCI firom otiier pigment-protein complexes is suggested as a concomitant effect of Ihe second FTC maximum.
The relationship between ash content and carbon isotope discrimination (Δ) was studied in durum wheat (Triticum durum Desf.) grown in a Mediterranean region (Northwest Syria) under three different water regimes (hereafter referred to as environments). In two of these environments, 144 genotypes were cultivated under rain-fed conditions. In the third environment, 125 genotypes were cultivated under irrigation. Ash content was measured in the flag leaf about 3 weeks after anthesis, whereas Δ was analysed in mature kernels. Total transpiration of the photosynthetic tissues of the culm contributing, from heading to maturity, to the filling of kernels was also estimated. Leaf ash content, expressed either on dry matter or leaf area basis or as total ash per blade, correlated positively (p< 0.001) with Δ in the three environments. However, this relationship was not the result of a positive correlation across genotypes between Δ and tissue water content. Moreover, only a small part of the variation in Δ across genotypes was explained by concomitant changes in ash content. When all genotypes across the three environments were plotted, Δ and ash content followed a non-linear relationship (r2 = 74), with Δ tending to a plateau as the ash content increased. However, for the set of genotypes and environments combined, total ash content per leaf blade was positively and linearly related (r2 = 0.76) with the accumulated culm transpiration. The non-linear nature of the relationship between ash content and Δ is sustained by the fact that culm transpiration also showed a non-linear relationship with kernel Δ. Therefore, differences in leaf ash content between environments, and to a lesser extent between genotypes, seem to be brought about by variations in accumulated transpiration during grain formation. and J.
