The Municipal Library in Bautzen houses a lot of Czech manuscripts which are dealt with by special literature, but the illuminations of which are known very scarcely. The decoration of the collection of work by Jan Hus (Ms. fol. 51) can be narrowed to the middle of the 15th century; the present date of 1412 is based on an entry in fol. 137v and is untenable because it is the text, not the decoration which came into existence in this year. The depictions – the figural and the heraldic ones – were added to the manuscripts supplementally; it is probably a picture of Jan Hus mounting the pulpit and a coat of arms of a member of the Hroznata family, maybe of the Kladruby abbot Bušek of Vrtba or of the front warrior of the Catholic Side, Burian of Gutštejn. The collection of theological-juridical texts (Ms. fol. 56) contains moreover yearly records; only one text item (Řeči besední) can be attributed to Tomáš Štítný of Štítné. The decoration of the codex is limited only to one fi gural illumination and one ornamental initial. Its style is quite advanced; it can most likely be dated to the 1470s.
Leaf chlorophyll (Chl) content, net photosynthetic rate (P^) and biomass production were estimated at monthly intervals in Chukrasia tabularis, Dolichandrone atrovirem, Eugenia Jambolana, Gmelina arborea, Lannea coromandelica, Terminalia arjuna and Terminalia bellerica from September 1990 to August 1991. The leaves of all the seven tree species showed significantly higher Chl content during summer than in winter, when it was expressed on area and/or fresh mass basis. Chl concentration showed marked variations from month to month and these differed from one plant species to the other. Clear positive correlations were found between Chl content and and/or biomass production in all the seven deciduous forest tree species studied. The scope for screening and selecting the right type of tree species prospective for energy plantations can be based on a simple technique such as estimation of leaf Chl content and PN.
