Investigating The Effects Of Temperature On Lesser Celandine, Regina Bellian
Investigating The Effects Of Temperature On Lesser Celandine, Regina Bellian
The Downtown Review
This paper explores invasive species Ficaria verna (Lesser celandine) and the effects of temperature on its growth. Trials were completed with two treatments, 13OC cold temperature and 20OC ambient temperature. Germinated bulbils of Lesser celandine were planted on February 15, 2017 and placed in their respective growing chambers. The plants were watered weekly and monitored for growth until harvest on March 29, 2017. Upon harvest, the plants’ height, largest leaf diameter and biomass were measured after extraction from soil and the removal of the leftover soil debris. Average height was found to be 11.66cm for the cold treatment and 5.14cm …

Community-scale surveys of plant drought tolerance are essential for understanding semi-arid ecosystems and community responses to climate change. Thus, there is a need for an accurate and rapid methodology for assessing drought tolerance strategies across plant functional types. The osmometer method for predicting leaf osmotic potential at full turgor ((o)), a key metric of leaf-level drought tolerance, has resulted in a 50-fold increase in the measurement speed of this trait; however, the applicability of this method has only been tested in woody species and crops. Here, we assess the osmometer method for use in herbaceous grassland species and test whether …
