Comparative study of trichomes in three parental „solanum” species and their somatic hybrids, cultivated in greenhouse or phytotron
Keywords:
Colorado potato beetle, Solanum chacoense, somatic hybrids, trichomes.Abstract
Trichomes represent one of the most important anatomical structure of plants, involved in protecting them against herbivores or other pathogens. The aim of our study was to compare trichome morphology in Solanum parental species and sexual or somatic hybrids cultivated in a greenhouse or phytotron. The analysis were performed on the leaf abaxial epidermis by using light and epifluorescent microscopy. In total, six out of the eight types of Solanum specific trichomes, firstly described by Luckwill (1943), were found. There were not significant differences between the plants grown in phytothron or greenhouse. However, we observed variation in the trichomes morphology in different hybrid plants as compared to their parents.
