Considering predicted climate change and the likelihood of increased drought and reduced water quality due to salinization and other issues, there is a growing need for the use of plants that can tolerate these factors with minimal negative impacts to plant vigor and yields. The westside of California's San Joaquin Valley is a prime example of a region already impacted by these difficulties. A potential new crop tolerant to such conditions is the caper plant, Capparis spinosa. This species is widely recognized for its ability to survive in the harshest of environments, tolerating excessive heat, drought, and soil salinity. However, there is little published information regarding this species' ability to tolerate high concentrations of the necessary plant nutrient Boron, an element found in higher concentrations in this region. Interestingly, Boron's range in plants between necessity and toxicity is extremely narrow, with both deficiency and toxicity having detrimental effects on plant health. One objective of this research was to establish a preliminary LC50 of Boron in caper plants. To do so, efforts to propagate this species asexually via rooted cuttings were conducted to establish clonal lines for subsequent Boron toxicity analyses. In total and via multiple attempts, 190 caper plants were produced out of which, 112 one-year-old plants were randomly selected and placed into a Randomized Complete Block Design experiment that consisted of 14 blocks that were treated daily with, 0 - 35 ppm Boron for 12 weeks throughout the summer 2022 growing season. The results of this study were two-fold: 1) asexual propagation of this species via rooted cuttings is inherently difficult and warrants additional research, and 2) under containerized laboratory conditions, this species appeared to be moderately tolerant to high levels of plant available Boron, with an established LC50 of 19.1 ppm, indicating this species may have potential benefits in the San Joaquin Valley's westside as a nectar and pollen source, soil remediation and stabilizer, and as a specialty crop for beginning and small farm operations.
