Test the ability of signaling compounds to help canola plants overcome temperature stresses in controlled environment and field experiments
ECODA project number: B.2.1
Principal investigator: Donald L. Smith
Executive Summary
The objective of this sub-activity was to understand the potential for microbe-to-plant signaling compounds such as lipochitooligosaccharides (LCOc) and thuricin 17 to help canola plants deal with stressful growing conditions.
Treatment of canola seeds with micromolar (μM) LCO solution indeed accelerated the emergence of young “fastplants” (a canola genotype developed for very rapid maturity) to a very significant degree and also increased seed yield. The application of this LCO solution to seed at planting promoted the regulation of plant leaf temperatures in greenhouse experiments, resulting in less extreme leaf temperatures following treatment. LCO spray treatment produced plants with longer branches, but increased apical dominance as well; which might be manipulated under field conditions to improve crop yield. Interestingly, when stress levels were extreme the signaling compounds could have negative effects.
Field experiments were conducted in each of 2011 and 2012. Field experiments were not required as part of the grant and the 2011 experiment was, therefore, seeded after all other seeding conducted as part of our summer field research, which — in combination with a period of drought and heat — led to very difficult growth conditions and variability of results; growth values for signaling compound treated material were generally higher than controls; however, the high variability masked significance. In 2012, LCO treatment resulted in greater production of branches, pods and biomass. In general, these signaling compounds do exhibit potential to modify growth and development of canola; further experiments will clarify the agronomic/commercial application of these materials.

Improving oil quality of Eastern Canadian canola
Improving oil quality of Eastern Canadian canola
ECODA project number: B.2.5, B.2.6 and B.2.7
Principal investigator: Hugh J. Earl
Objectives:
In this project, it was proposed to develop a controlled environment stress protocol that would provide a mechanism to pre-screen candidate canola varieties for susceptibility to elevated FFAs under heat stress.
This project also investigated the hypothesis that applications of foliar boron (B) to canola during early flowering could result in significant yield increases and that these increases would be greatest when the crop was under high temperature stress during flowering. A further objective was to elucidate the physiological basis of foliar boron’s effect on the canola crop.

Integrated management of stem rot (Sclerotinia sclerotiorum) of canola in Eastern Canada including ON, QC, NB, NS and PEI
Integrated management of stem rot (Sclerotinia sclerotiorum) of canola in Eastern Canada including ON, QC, NB, NS and PEI
Categories: Canola; Diseases
ECODA project number: B.3
Principal investigator: Balakrishnan Prithiviraj
Executive Summary
In this project over one hundred canola genotypes were screened for stem rot resistance. However, the screening was not fruitful due to low incidence of stem rot at experimental sites. Similar issue prevailed in the field sites in which seven fungicides were screened for their efficacy against stem rot disease in Eastern Canada.
Testing marine bioproducts for the management of stem rot disease yielded two potential candidates: Ascophyllum nodosum extract (=seaweed extract) and λ-carrageenan. Both the products reduced the incidence and severity of the disease. Further field evaluation of these products is recommended.
