We suggest that in this system seed set is not limited by pollination but by other factors, possibly nutritional resources. However, the mean seed set per flower (1.18) was far below the maximum possible (4 per flower).
Variation in seed set was not explained by the numbers of bumblebees attracted or by the number of inflorescences they visited for any bee species. Overall the visitation rate per inflorescence and seed set per flower was independent of the number of inflorescences per plant. Once attracted, all bee species visited more inflorescences per plant on plants with more inflorescences. pascuorum exhibited no increase in recruitment according to display size. terrestris were attracted to plants with larger floral displays, but B. More individuals of Bombus pratorum and the nectar-robbing B. Penggunaan lain yang tidak terbukti dengan penyelidikan termasuk luka kulit, ulser kulit, batuk, sakit tekak, penyakit gusi, sakit sendi, cirit-birit, dan keadaan lain. Bumblebee species differed in their response to the size of floral display. Comfrey telah digunakan dalam ubat alternatif sebagai bantuan yang berkesan untuk mengubati sakit belakang, osteoartritis, atau kelembutan dan pembengkakan yang disebabkan oleh kecederaan luka. & Thoms Brotowali Akar Tinosporae Crispae Radix Selain itu, terdapat beberapa tumbuhan yang dilarang untuk digunakan dengan klaim tertentu, antara lain: No Nama Tumbuhan (Spesies) Nama Simplisia Klaim 1.
We examine the relationships between numbers of inflorescence per plant, bumblebee foraging behaviour and seed set in comfrey, Symphytum officinale, a self-incompatible perennial herb. Symphytum officinale Komfrey Daun Symphyti Folium 48. We may expect more visits to plants with more flowers, but do these large plants receive more or fewer visits per flower than small plants? Do all pollinator species respond in the same way? We would also expect foragers to move less between plants when the number of flowers per plant are large, which may reduce cross-pollination compared to plants with few flowers. The fecundity of insect-pollinated plants may not be linearly related to the number of flowers produced, since floral display will influence pollinator foraging patterns.
