  • Herbicides by Jordan Eyamie a Thesis
    Halosulfuron Interactions with Other Processing Tomato (Lycopersicon esculentum Mill.) Herbicides By Jordan Eyamie A Thesis Presented to The University of Guelph In partial fulfilment of requirements for the degree of Master of Science in Plant Agriculture Guelph, Ontario, Canada © Jordan Eyamie, May, 2019 ABSTRACT HALOSULFURON INTERACTIONS WITH OTHER PROCESSING TOMATO (LYCOPERSICON ESCULENTUM MILL.) HERBICIDES Jordan Eyamie Advisor(s) University of Guelph 2019 Dr. Darren Robinson Tomatoes are an economically important crop in Ontario that can be adversely affected by weed interference. Halosulfuron is a relatively new herbicide that can provide broad-spectrum weed control when applied in a tankmix solution and can provide solutions for growers who have triazine-resitant weeds. Herbicide tankmixes could interact antagonistically, additively or synergistically. Experiments in Ridgetown, ON were repeated 4 times over 2 years (2015 and 2016) in order to determine if there were any antagonistic, additive or synergistic interactions on tomato injury and weed control efficacy between halosulfuron at three rates (25, 37.5 and 50 g ai ha-1) and commonly used POST and pre-transplant tomato herbicides. Results suggested no increase in tomato injury. There were additive interactions between halosulfuron and other broadleaf tomato herbicides. Results showed antagonistic interactions between halosulfuron and POST tomato graminicides. Halosulfuron will provide growers with an additional tool to improve weed control and combat triazine-resitant weeds. ACKNOWLEDGEMENTS There are so many people to thank who contributed to the completion of this thesis. Thank you to Rene VanAcker for encouraging me to go-outside my comfort zone and pursue a project in Ridgetown with Darren Robinson.

    Liu et al. Bot Stud (2016) 57:28 DOI 10.1186/s40529-016-0145-7 ORIGINAL ARTICLE Open Access Effect of light regime and provenance on leaf characteristics, growth and flavonoid accumulation in Cyclocarya paliurus (Batal) Iljinskaja coppices Yang Liu1, Chenyun Qian1, Sihui Ding1, Xulan Shang1,2, Wanxia Yang1,2 and Shengzuo Fang1,2* Abstract Background: As a highly valued and multiple function tree species, Cyclocarya paliurus is planted and managed for timber production and medical use. However, limited information is available on its genotype selection and cultiva- tion for growth and phytochemicals. Responses of growth and secondary metabolites to light regimes and genotypes are useful information to determine suitable habitat conditions for the cultivation of medicinal plants. Results: Both light regime and provenance significantly affected the leaf characteristics, leaf flavonoid contents, biomass production and flavonoid accumulation per plant. Leaf thickness, length of palisade cells and chlorophyll a/b decreased significantly under shading conditions, while leaf areas and total chlorophyll content increased obviously. In the full light condition, leaf flavonoid contents showed a bimodal temporal variation pattern with the maximum observed in August and the second peak in October, while shading treatment not only reduced the leaf content of flavonoids but also delayed the peak appearing of the flavonoid contents in the leaves of C. paliurus. Strong correla- tions were found between leaf thickness, palisade length, monthly light intensity and measured flavonoid contents in the leaves of C. paliurus. Muchuan provenance with full light achieved the highest leaf biomass and flavonoid accu- mulation per plant. Conclusions: Cyclocarya paliurus genotypes show diverse responses to different light regimes in leaf characteristics, biomass production and flavonoid accumulation, highlighting the opportunity for extensive selection in the leaf flavonoid production.

We also discussed current research problems and provided insight into future relevant research.

Turf quality is crucial in lowest limit for its survival, the plant is considered to the development and maintenance of golf courses or endure low light stress. Shade is a common and inevitable sports turf. Current urban greening is mainly trees, shrubs problem in the landscape construction and management. and grass combination of the three organisms, but the High density planting or inapproprite three-dimensional understory trees or shrubs often bring the inevitable shady planting structure often leads to low light stress for lawn, while the high-rise is so crowded by the shade of the landscape plants.

However, the effects of varying light intensity on morphological and photoprotective mechanisms in Pinus massoniana seedlings have not been explored in depth, especially those in the first seedling growing season. We measured the growth, photosynthetic physiology, biochemistry, and chlorophyll fluores- cence of P. massoniana seedlings at four light gradients: 100% relative irradiance (RI, full sunlight), 70% RI, 50% RI, and 20% RI. The seedling height at 70% RI was 9.27% higher than that at 100% RI. However, seedling height was inhibited under low light intensity; at 20% RI, all seedlings died. The decreasing light intensity inhibited ground diameter growth but increased the height-diameter ratio. The secondary needle emergence rate was 53.4% higher at 70% RI than at 100% RI but was only 2% at 50% RI. The chlorophyll and carotenoid contents increased significantly with decreasing light intensity.

Environmental and Plant Biology The Population Ecology of a Perennial Clonal Herb Acorus calamus L. (Acoraceae) in Southeast Ohio, USA (153pp.) Director of Dissertation: Brian C. McCarthy Acorus calamus L. (Sweetflag, family Acoraceae) is an economically important helophyte found in temperate and subtropical wetlands. I examined edaphic factors influencing distribution of A. calamus populations; potential of the rhizome in wetland restoration; genetic diversity of populations; and, environmental factors influencing seed germination. Redundancy analysis (RDA) indicated that rhizome length and biomass, total number of leaf scars and leaf scars per unit length in A. calamus are positively related to a soil calcium content gradient. Shoot density is influenced most by a silt and nitrogen gradient but negatively related to organic matter. Multivariate Analysis of Variance indicated that light (λ = 0.762, P < 0.001), nutrient (λ = 0.449, P < 0.001) and moisture (λ = 0.508, P < 0.001) had significant effects on rhizome growth.

However, the mechanisms underlying the formation of leaf variegation in this species are still unclear. Here, the juvenile yellow leaves and mature variegated leaves of I. altaclerensis ‘Belgica Aurea’ were compared in terms of leaf structure, pigment content and transcriptomics. The results showed that no obvious differences in histology were noticed between yellow and variegated leaves, however, ruptured thylakoid membranes and altered ultrastructure of chloroplasts were found in yellow leaves (yellow) and yellow sectors of the variegated leaves (variegation). Moreover, the yellow leaves and the yellow sectors of variegated leaves had significantly lower chlorophyll compared to green sectors of the variegated leaves (green). In addition, transcriptomic sequencing identified 1675 differentially expressed genes (DEGs) among the three pairwise comparisons (yellow Citation: Zhang, Q.; Huang, J.; Zhou, P.; Hao, M.; Zhang, M.
