Rorippa sylvestris, Creeping Fieldcress: A Threat to Production Ornamentals and Its Control

Wait or escape? Contrasting submergence tolerance strategies of Rorippa amphibia, Rorippa sylvestris and their hybrid.

BACKGROUND AND AIMS Differential responses of closely related species to submergence can provide insight into the evolution and mechanisms of submergence tolerance. Several traits of two wetland species from habitats with contrasting flooding regimes, Rorippa amphibia and Rorippa sylvestris, as well as F(1) hybrid Rorippa × anceps were analysed to unravel mechanisms underlying submergence toler...

Different flooding responses in Rorippa amphibia and Rorippa sylvestris, and their modes of expression in F1 hybrids.

The river floodplain species Rorippa amphibia, Rorippa sylvestris, and their hybrid Rorippa x anceps were studied here, with the aim of identifying potential species differences with respect to flooding tolerance, and of assessing their expression in F1 hybrids. Parents and their F1 hybrids were subjected to three flooding treatments mimicking natural conditions, and growth-related and leaf mor...

Autotoxicity in Vegetables and Ornamentals and Its Control

Control of Insects and Mites on Ornamentals

DRESENT INTEREST in grow' ing ornamental plants has created a demand for information on the control of the insects, mites and other pests attacking them. Requests for this information come from home gardeners, florists, nurseries and contract applicators. Until recently very little attention was given the problem since there was no satisfactory way of estimating monetary losses of ornamentals d...
