SHORT COMMUNICATION Reduced maternal fecundity of the high Andean perennial herb Alstroemeria umbellata (Alstroemeriaceae) by aphid herbivory
Assessments of the effects of invertebrate herbivores on high-altitude plants have seldom taken into account both mutualistic and antagonistic interactions. To evaluate the effect of herbivores (antagonists) and pollinators (mutualists) on the female reproductive success of the high-Andean perennial herb Alstroemeria umbellata, we separately and simultaneously excluded aphids (herbivores), and ...
متن کاملComparative karyotype analysis of populations in the Alstroemeria presliana Herbert (Alstroemeriaceae) complex in Chile
Alstroemeria L., one of the most diverse genera of the Chilean flora and of high floricultural value, is represented by 35 species, most of them distributed between 28-38° S in the Mediterranean zone of Central Chile. There are 24 complex-forming taxa, of which 18 have conservation problems (8 are considered "endangered" and 10 as "vulnerable"). One of these complexes is Alstroemeria presliana ...
متن کاملComparative karyotypic analysis in the Alstroemeria hookeri Lodd. (Alstroemeriaceae) complex sensu Bayer (1987)
Alstroemeria L. (Alstroemeriaceae) is an American genus of monocots with two principal distribution centers in Chile and Brazil. In Chile, it is represented by about 32 species, most of them in central Chile, an area known for its high level of endemism. The "complex" Alstroemeriahookeri is endemic to Chile, where it is distributed from the Coquimbo to the Bío-Bío Region. We analyzed the karyot...
متن کاملCHROMOSOME STUDIES OF IRANIAN MEMBERS OF TRIBE SOPHOREAE (FAMILY LEGUMINOSAE
The tribe Sophoreae sensu Polhill [9,10] is a large and diverse assemblage comprising the ancient and primitive ancestral stocks of Papilionoideae. The most frequent chromosome basic numbers in this tribe are x = 11 and x = 9 but chromosome numbers range from x = 8-14 are also known. In this study chromosome numbers and karyotype variation of Iranian members of tribe Sophoreae are reported. Ira...
متن کاملContact dermatitis in Alstroemeria workers.
Hand dermatitis is common in workers in the horticultural industry. This study determined the prevalence of hand dermatitis in workers of Alstroemeria cultivation, investigated how many workers had been sensitized by tulipalin A (the allergen in Alstroemeria) and took stock of a wide range of determinants of hand dermatitis. The 12-month period prevalence of major hand dermatitis amounted to 29...
