“…Sakamoto and Suzuki (2015b) found that root zone heating to 33 C significantly reduced leaf number in carrots (Daucus carota L. cv Tokinashigosun), whereas in lettuce, cooling root temperatures did not significantly change leaf number (Sun et al, 2016). However, in soybeans (Glycine max L.), increasing RZT increased leaf number (Dashti et al, 2016). Root weight and architecture are largely dependent on species because different species have different optimal temperatures (Luo et al, 2020).…”

Hydroponic systems have become increasingly popular for growers in recent years for year-round local production. Whereas optimal air temperature for plant growth has been considered, optimal root zone temperatures have not been examined as thoroughly. The objective of this research was to determine the optimal water temperature for growing different types of basil hydroponically. Research was conducted at the greenhouses in Stillwater, OK. Seventeen cultivars were selected from six main types of basil and transplanted into Nutrient Film Technique hydroponic systems, and three water temperature treatments were applied: 23, 27.5, and 31 °C. Height, width, average leaf area, leaf number, chlorophyll concentration (chlorophyll readings obtained with the Minolta-502 SPAD meter), shoot fresh weight, shoot dry weight, and root dry weight were evaluated. In general, the 27.5 and 31 °C treatments were not greater than each other in terms of leaf number and root dry weight but were greater than the 23 °C treatment. The 31 °C treatment had the greatest height, whereas width, average leaf area, shoot fresh weight, and shoot dry weight were not different from the 27.5 °C treatment. The 23 °C treatment had the greatest chlorophyll concentration (SPAD) value. Cultivar differences were significant in average leaf area and SPAD, with ‘Spicy Bush’ having the smallest leaf area and purple basil having the greatest SPAD value. For all cultivars except purple basil and ‘Large Leaf Italian’, a 27.5 °C water temperature would be recommended for greater plant growth.

“…A vast array of traditional methods has been explored to optimise the performance of legumes under environmental fluctuations in their planting fields. Inoculation of the soil with arbuscular mycorrhizal (AM) fungi, growth-promoting microbes as well as rhizobial communities have been utilised to improve micronutrient availability, growth, and development of the crops, to enhance nodulation and subsequently, nitrogen fixation [30,31]. Other traditional methods, some of which are still being applied to date, including the optimisation of cropping systems, have also been proven to play an imperative role in the propagation of stresstolerant crops [18].…”

Over the past few years, many cultivated plants have been under scrutiny for their potential role in economic, agroecological, nutritional, and scientific innovation sectors, especially in various developing countries. This was aimed to identify plants that have the potential to alleviate food insecurity, improve agroecosystems while benefiting the producers financially as well. Such important crops have been studied and are continuously undergoing improvements to produce cultivars that confer biotic and abiotic stress tolerance, enhanced shelf-life, nutritional quality, and environmental benefits. This chapter reviews the benefits provided by globally cultivated legumes, the challenges faced during their propagation, the methods used to enhance these crops, and the constraints they undergo during genetic improvement. It further analyses the strategies that have been employed thus far to optimise genetic transformation.

“…In addition, soybean, must effectively cope with various abiotic stressors that have an impact on its production, including frost, water stress, and iron deficiency chlorosis (IDC). In addition to abiotic stressors, soybean must also compete with biotic stressors such as Fusarium virguliforme, which causes sudden death syndrome, Aphis glycines (soybean aphid), Sclerotinia sclerotiorum, responsible for sclerotinia stem rot, and Heterodera glycines Ichinohe, commonly known as soybean cyst nematode (SCN) (Dashti et al 2016;Gabruch and Gietz 2014;.…”

Soybean is a globally important crop due to its wide range of uses, including providing protein for human consumption, high-quality nutrients for animal feed, and applications in biofuel production. Additionally, legume crops like soybean hold advantages because of their symbiotic association with nitrogen-fixing bacteria. As the global population continues to rise, the demand for food is increasing rapidly. However, agricultural production alone cannot meet this growing demand, necessitating research efforts to expand soybean cultivation further into Manitoba, Saskatchewan and Alberta.These Canadian provinces possess abundant productive agricultural land and hold great potential for soybean cultivation.When considering soybean cultivation in those regions of Canada, many key traits must be considered. Two important considerations stand out: time of flowering and maturity, and resistance to soybean cyst nematode (SCN). Hence, the objectives of this Statement of ContributionI, Nour Nissan, performed all experiments, analyzed the data, created figures and tables, and wrote the entirety of this thesis. Dr. Bahram Samanfar supported this research through funding, guidance, editorial review, and approval of all written chapters. Major thanks to Dr. Elroy Cober for providing us with plant material for chapters one and two, and for his valuable comments on my written work, including my manuscripts and this thesis. Regarding chapters two and five, I would like to acknowledge Genome Quebec sequencing platform for their sequencing support, and Francois Lefebvre and his lab members lab for their RNA-seq preliminary data analysis. Last but not least, a big thank you to Dr. Benjamin Mimee for his wisdom regarding the analysis for chapters four and five.
