540 Field-grown Garden Chrysanthemum Responses to Pinching and Plant Date

Growth and Flowering Responses of Cut Chrysanthemum Grown under Restricted Root Volume to Irrigation Frequency

Influences of irrigation frequency on the growth and flowering of chrysanthemum grown under restricted root volume were tested. Chrysanthemum cuttings (Chrysanthemum morifolium "Reagan White") were grown in seedling tray which contained coconut peat in volumes of 73 and 140 cm(3). Plants were irrigated with drip irrigation at irrigation frequencies of 4 (266 mL), 6 (400 mL), and 8 (533 mL) time...

Responses to Aggregation Pheromones for Five Carpophilus Species ( Coleoptera : Nitidulidae ) in a California Date Garden

Environ. Entomol. 23(6): 1534-1543 (1994) ABSTRACT The nitidulid species, Carpophilus mutilatus Erichson, C. hemipterus (L.), C. freemani Dobson, and C. obsoletus Erichson, responded to their aggregation pheromones during a 17-mo study in a California date garden. The pheromones were dramatically synergized by volatiles from fermenting whole-wheat bread dough; pheromones alone attracted only 1....

Epigenetic population differentiation in field‐ and common garden‐grown Scabiosa columbaria plants

Populations often differ in phenotype and these differences can be caused by adaptation by natural selection, random neutral processes, and environmental responses. The most straightforward way to divide mechanisms that influence phenotypic variation is heritable variation and environmental-induced variation (e.g., plasticity). While genetic variation is responsible for most heritable phenotypi...

Assessment of Habitat Suitability Is Affected by Plant-Soil Feedback: Comparison of Field and Garden Experiment

BACKGROUND Field translocation experiments (i.e., the introduction of seeds or seedlings of different species into different localities) are commonly used to study habitat associations of species, as well as factors limiting species distributions and local abundances. Species planted or sown in sites where they naturally occur are expected to perform better or equally well compared to sites at ...
