The Synchronization Of Nocturnal Pollinator Behavior And Apple Flower Nectar Production, Madison Jennings

Biological Sciences Undergraduate Honors Theses

Insects perform an essential ecological service by facilitating the pollination of crops for food production worldwide. Recent declines in diurnal bee populations threaten food security and has led to growing concerns about existent pollination methods. Pollination contributions by native nocturnal insects have been documented to occur in a variety of systems, thought to be supported by the plant’s attractant and reward system. If this is the case, pollination of flowers by nocturnal vectors may be influenced by circadian cycles of nectar production and insect activity. To test this hypothesis, we recorded insect abundance of nocturnal pollinators periodically throughout the night …

Research Report: High Tunnel Tomato Fruit Cluster Pruning, Caterina Roman, Rebecca G. Sideman

Faculty Publications

Tomatoes are a high value crop grown worldwide. Indeterminate varieties are commonly grown in high tunnel structures throughout New England for the fresh market. Indeterminate tomato plants often suffer from a phenomenon called ‘June drop’ in which the plant’s first four to five cluster of fruit set perfectly but the subsequent two to three clusters have poor set and plant productivity drops suddenly. While cluster thinning (e.g., reducing the number of fruit allowed to mature per cluster) has been successfully shown to increase fruit size, it has generally not increased marketable yield. We hypothesized that reducing the fruit load by …
