Leaf-size and leaf-shape were followed on expanding leaves of mature sporophytes of four Dryopteris species cultivated for more than 7 years in Sapporo. Blade length(BL, cm), leaf length(LL)and blade width(W)were measured. as an indicator of leaf-size, and BL/W and BL/LL ratios were calculated to generate leaf-shape indices during leaf growth from April to June at 2-8 day intervals. Following BL/W changes as a function of LL increase could be used to characterize different stages of leaf growth between Dryopteris laeta and D. austriaca, and between D. crassirhizoma and D. coreanamontana; however both of these two species had almost similar BL/W and LL on-expanded leaves, respectively. The speed of leaf elongation(dLL/dT, cm/day)was also included for characterization of leaf expansion. Based on relative changes(%)between the maximum and minimum values of BL/W, BL/LL and dLL/dT, six categories could be recognized during the process of leaf expansion.

Summary After the C-banded interphase nuclei and mitotic metaphase chromosomes of Nigella damascena were sequentially stained with CMA and DAPI, the centromeric C-dots of all chromosomes displayed bright fluorescence with DAPI and the interstitial C-bands located at the secondary constricted regions of three pairs of metacentric chromosomes displayed fluorescence with CMA. The other C-bands were also brightly fluoresced with either CMA or DAPI.

Klekowski has discussed on mutation, developmental selection, and plant evolution in his recent text book(1988). He has discussed on various problems from the molocule to the population. In the present article, his discussions are reviewed mainly from the standpoints of anatomy and organography.

The specific localization and unique shape of the chloroplast nucleoid(ct-nucleoid)in the pyrenoid of C. okamurae Web. v. Bos. were revealed by fluorescence microscopy after staining with the DNA specific fluorochrome 4'6-diamidino-2-phenylindole(DAPI).
