Abstract: Mexico is a center of diversity for Solanaceae. Our objective is to analyze the species diversity and geographical distribution of the Solanaceae in Jalisco. The data come from 3 405 herbarium specimens. An analysis of these specimens indicates that the Solanaceae in Jalisco are represented by 20 genera, 138 species and 140 taxa. Four genera, Solanum (55 species), Physalis (35), Cestrum (10) and Lycianthes (9) represent 79% of the total number of species. In contrast, Brachistus, Browallia, Chamaesaracha, Jaltomata, Juanulloa, Lycium, Nectouxia, Nicandra and Nierenbergia have only 1 species each. In Jalisco, the Solanaceae are widely distributed throughout the state occurring at altitudes ranging from sea level to 3 400 m. Mostly, they grow in conifer and oak forest (81 species) followed by tropical subdeciduous forest (57), tropical deciduous forest (54), and cloud forest (43). Fifty-one species are commonly found in disturbed and ruderal areas. Lycianthes jalicensis, Physalis lignesens, P. longipedicellata, P. longiloba and P. tamayoi are endemic to the state. These results indicate that Jalisco ranks fourth in species diversity for Solanaceae after the states of Oaxaca, Chiapas and Veracruz.

Abstract: The susceptibility of fabaceous (Lupinus and Lathyrus spp.) and solanaceous (Calibrachoa, Browallia, Nicotiana, Nierembergia, and Petunia spp.) ornamental plants compared with straightneck squash (Cucurbita pepo) inoculated with Phytophthora capsici and P. tropicalis was investigated in greenhouse studies. Four P. capsici isolates and one P. tropicalis isolate were evaluated. Flowering tobacco (Nicotiana × sanderae), sweet pea (Lathyrus latifolius), lupine (Lupinus polyphyllus), squash, and million bells (Calibrachoa × hybrida) were susceptible to P. capsici and P. tropicalis. Bush violet (Browallia speciosa) and cup flower (Nierembergia scoparia) were not susceptible to either pathogen. Petunia (Petunia × hybrida) was susceptible to P. capsici but not P. tropicalis. Area under the plant growth curve (AUPGC) was also affected in some susceptible plants. AUPGC was significantly different in inoculated plants compared with the untreated controls of Nicotiana and Calibrachoa. In addition, six Calibrachoa cul...

Abstract: MEXICO IS A CENTER OF DIVERSITY FOR SOLANACEAE. OUR OBJECTIVE IS TO ANALYZE THE SPECIES DIVERSITY AND GEOGRAPHICAL DISTRIBUTION OF THE SOLANACEAE IN JALISCO. THE DATA COME FROM 3 405 HERBARIUM SPECIMENS. AN ANALYSIS OF THESE SPECIMENS INDICATES THAT THE SOLANACEAE IN JALISCO ARE REPRESENTED BY 20 GENERA, 138 SPECIES AND 140 TAXA. FOUR GENERA, SOLANUM (55 SPECIES), PHYSALIS (35), CESTRUM (10) AND LYCIANTHES (9) REPRESENT 79% OF THE TOTAL NUMBER OF SPECIES. IN CONTRAST, BRACHISTUS, BROWALLIA, CHAMAESARACHA, JALTOMATA, JUANULLOA, LYCIUM, NECTOUXIA, NICANDRA AND NIERENBERGIA HAVE ONLY 1 SPECIES EACH. IN JALISCO, THE SOLANACEAE ARE WIDELY DISTRIBUTED THROUGHOUT THE STATE OCCURRING AT ALTITUDES RANGING FROM SEA LEVEL TO 3 400 M. MOSTLY, THEY GROW IN CONIFER AND OAK FOREST (81 SPECIES) FOLLOWED BY TROPICAL SUBDECIDUOUS FOREST (57), TROPICAL DECIDUOUS FOREST (54), AND CLOUD FOREST (43). FIFTY-ONE SPECIES ARE COMMONLY FOUND IN DISTURBED AND RUDERAL AREAS. LYCIANTHES JALICENSIS, PHYSALIS LIGNESENS, P. LONGIPEDICELLATA, P. LONGILOBA AND P. TAMAYOI ARE ENDEMIC TO THE STATE. THESE RESULTS INDICATE THAT JALISCO RANKS FOURTH IN SPECIES DIVERSITY FOR SOLANACEAE AFTER THE STATES OF OAXACA, CHIAPAS AND VERACRUZ
