The growth and morphology of native Cflltaegus mOllogYlla Jacq. (Rosaceae) obtained from an upland population in mid-Wales was compared with that of commercially obtained material of Hungarian provenance in an upland trial. 2. Six months after planting. the native plants were 35% taller. 70% more branched and had twice the total stem length and four times as many thorns per thorny plant than the commercial material. 91 'le of native plants were thorny compared with only 20% of commercial plants. Commercial plants had larger leaves, longer petioles and a greater severity of powdery mildew attack than the natives. 3. It was possible, using vegetative characters, to separate HH% of the natives from 80% of the commercial plant; on the basis of their growth and morphology using discriminant analysis. Native seed was significantly smaller in size than the commercial seed which suggests that the measurement of reproductive characters would allow further discrimination between the two groups Permalink : https://biblio.cbnpmp.fr/index.php?lvl=notice_display&id=155157 Jones, Andrew Thomas, Evans, P.R. 1994 A comparison of the growth and morphology of native and commercially obtained continental European Cratageous monogyna Jacq.
