The verification of species of agrostis by means of morphological characters of the florets

, : The verification of species of agrostis by means of morphological characters of the florets. Landwirtschaftliche Forschung 31(4): 359-369

The percentage distribution of the following recognizable characters of the florets of Agrostis spp. was determined: the form of the palea apex; the presence and angle of basal hairs; the presence, kind and insertion of awns; descriptive diagnostic characters were studied with respect to their reliability in determining the genuineness of the species. It is possible to determine the genuineness of the bulk of samples by means of the measurement of the length and the width of the floret, and of the lengths of the palea and the caryopsis. The advantages of this quantitative morphometric method compared with qualitative descriptive method is indicated. Results are discussed in connection with purity analysis and verification of species in seed testing of Agrostis. A. tenuis cv. Highland is apparently a form different from A. tenuis, i.e., according to Scholz A. castellana B. et R.
