The evaluation of cold hardiness in Corylus

Creator:: Chozinski, Annie M.
Abstract:: Anthesis of both staminate and pistillate flowers of Corylus occurs in midwinter. To insure adequate pollination and nut set, these flowers must attain a sufficient hardiness level to withstand low temperatures. This study estimated cold hardiness of Corylus cultivars and species using laboratory freezing of shoots without artificial hardening. In...

The interaction of photosynthesis and auxin transport during adventitious root formation in Pisum sativum L. stem cuttings and the effect of stock plant etiolation on rooting

Creator:: Kumpula, Carol L.
Abstract:: Adventitious root formation can be inhibited in stem cuttings of Pisum sativum L. (pea), an easy-to-root species, if the apical and lateral buds are removed. Application of exogenous auxin to the apical stump can replace the rooting stimulus produced by the buds. Root number was reduced by 50 to 100%...
