Description
| - Podle hypotézy o vývoji zvýšené kompetiční schopnosti (EICA), nepůvodní invazní rostliny jsou mohutnější než rostliny téhož druhu v původním areálu v důsledku rozdílné distribuce sušiny. Porovnávali jsme tyto charakteristiky u nepůvodních severoamerických a původních evropských rostlin kypreje vrbice (Lythrum salicaria L.) ve 3letém venkovním kultivačním pokusu se sérií vzájemných náhrad rostlin, při různé dodávce minerálních živin a vody. Každoročně jsme hodnotili výšky prýtů, počty stonků a fenologii kvetení. Rostliny jsme sklidili po 3 letech a zjistili distribuci jejich sušiny. Výšky prýtů a počty stonků závisely pozitivně na zásobení živinami, ale průkazných mezipopulačních rozdílů bylo málo. Severoamerické rostliny kvetly později než evropské. Kompetiční schopnost, hodnocená jako relativní výnos sušiny, byla většinou jen neprůkazně rozdílná. Naše výsledky nepodporují hypotézu EICA. Jiné faktory mohou být důležitější pro odlišení domácích a nepůvodních invazních populací. (cs)
- According to the evolution of increased competitive ability (EICA) hypothesis, non-native invasive plants are larger than plants of the same species growing in their native range because of different dry weight allocation patterns. Competitive abilities of non-native North American and native European Lythrum salicaria populations were tested against each other in a 3-year common garden experiment using a replacement series design at different nutrient and water levels. Shoot height, stem number and flowering were recorded annually. Plants were harvested after 3 years and their weight allocation patterns determined. Shoot heights and stem numbers were positively related to nutrient levels but few significant between-population differences were found. The North American plants flowered later than European ones. Competitive ability, measured as relative yield, was mostly non-significantly different. Our results do not support the EICA hypotesis. Other factors may be more important.
