| an experimental test of hybrid resistance to insects and pathogens using salix caprea, s. repens and their f1 hybrids. | the aim of this study was to assess the responses of herbivores and pathogens to hybrid plants under controlled conditions. f1 hybrids and parental species, produced by hand-pollinating willows in the field, were potted and kept in an experimental field under controlled conditions. in 1997, plant growth and survival were measured along with densities of insects and the degree of pathogen infection on the willows. the survival rate was higher for s. repens than for the hybrids and lowest for s. c ... | 1998 | 28308478 |
