Plants often grow in clusters of various sizes and have a variable number of flowers per inflorescence. This small-scale spatial clustering affects insect foraging strategies and plant reproductive success. In our study, we aimed to determine how visitation rate and foraging behaviour of pollinators depend on the number of flowers per plant and on the size of clusters of multiple plants using D...

Microscopic observation of bi-weekly sampled terminal buds revealed that most flower buds of R. mucronatum were formed between late-July and mid-August and differentiation of specific floral organs was completed before mid-October. Flower buds continued to enlarge through the winter. When flower buds on two-yearold plants from rooted cuttings were allowed to grow at day / night temperature of 1...

Catharanthus roseus or vinca produces over 130 TIAs with pharmaceutical value. Two of them, namely vinblastine (VB) and vincristine (VC), are species-specific and extensively used in anticancer chemotherapeutics. To detect C. roseus genotypes abundant in desired TIAs, contrasting genotypes should be analyzed via marker-assisted selection (MAS) to avoid analytical quantitation. A trustable morph...

Data on plant-pollinator interactions collected over six summers in montane meadows of the HJ Andrews Experimental Forest provided an opportunity to explore the association between two genera of generalist pollinators: Apis and Bombus. Ten plots in each meadow were “watched” for fifteen minutes five times every summer, and each flower species in a meadow-watch was assigned a class based on the ...

Development of composite inflorescences in the plant family Asteraceae has features that cannot be studied in the traditional model plants for flower development. In Gerbera hybrida, inflorescences are composed of morphologically different types of flowers tightly packed into a flower head (capitulum). Individual floral organs such as pappus bristles (sepals) are developmentally specialized, st...
