Cataloguing orchids from watercolours in Surinam Orchids (1823-1833)
This studentship will involve checking the listed plant names against images of watercolours of orchids in
Surinam Orchids for accurate identification and record any changes to current use of plant names, as well as recording inscriptions as seen on the drawings, to support final cataloguing of the collection. Many of the illustrations are examples of early introductions and demonstrate the importance of illustrations for identifying and recording new plant species.
Companion planting for home gardeners: attracting natural enemies of aphids with the poached egg plant Limnanthes douglasii
Companion planting is often suggested as an effective way of insect management within gardens and allotments, but there are very few studies looking at reliable companion planting combinations and therefore a shortage of practical information for the home gardener. This project will be investigating whether planting
Limnanthes douglasii (Poached egg plant) around cabbages to attract hoverflies is an effective way of managing mealy cabbage aphids.
Development of methods for studying within-genus variation in resistance to Armillaria root rot in multiple Ligustrum host species
The project aims to assess within-genus differences in resistance to Armillaria root rot in various species of the common hedging plant, Privet. To achieve this, the student will develop methods to measure the progression of symptomatic mycelial fans through root sections of different species and will optimise methods of propagating Privet cuttings. The project will also survey RHS members and garden centres to provide information on the distribution of some of the most susceptible host species throughout the UK.
Investigating local authority data collection on survivorship and diversity within urban tree plantings
This studentship project aims to enhance understanding of urban tree populations’ vulnerability to climate-change related impacts by collecting data from English councils on tree survival rates and urban specimen selection, including sapling production from seed or vegetative propagation, which has genetic diversity implications. Findings will enhance awareness of urban tree vulnerability to climate-related impacts and help influence policy to enhance resilience of new plantings going forward.
