Phenotypic integration in style dimorphic daffodils (Narcissus, Amaryllidaceae) with different pollinators.
Different pollinators can exert different selective pressures on floral traits, depending on how they fit with flowers, which should be reflected in the patterns of variation and covariation of traits. Surprisingly, empirical evidence in support of this view is scarce. Here, we have studied whether the variation observed in floral phenotypic integration and covariation of traits in Narcissus sp...
متن کاملFlower development and senescence in Narcissus tazetta ‘Kashmir Local’
Flower development and senescence was studied in Narcissus tazetta ‘Kashmir Local’. Flower development was divided into six stages (I-VI), from the tight bud stage to the senescent stage. Flower fresh and dry weight increased as the flowers progressed from bud to bloom and then declined during senescence. Membrane permeability of tepal tissues increased as the flower progressed through various ...

متن کاملFT-like NFT1 gene may play a role in flower transition induced by heat accumulation in Narcissus tazetta var. chinensis.
The low-temperature flowering-response pathway, used as an inductive stimulus to induce flowering in plant species from temperate regions in response to cold temperature, has been extensively studied. However, limited information is available on the flower transition of several bulbous species, which require high temperature for flower differentiation. Narcissus tazetta var. chinensis (Chinese ...
