The interactions between applied biostimulants, photosynthesis, grain yield and growth temperatures in winter and spring wheat varieties

Inocucor Technologies Inc.（简称：Inocucor）是一家加拿大公司，专门从事可持续植物微生物农产品的开发。健康的土壤包括促进植物生长的细菌的增殖群落，这些细菌有助于提高作物产量。因此，用有益的细菌群落丰富土壤和用生物刺激剂处理植物代表了Inocucor提供的产品。该公司的第一代in - m1产品目前在美国22个州销售，用于高价值农产品，该公司的第二代产品已在15个州注册，用于行作物。由于全球气温上升，加拿大农民经历了比平常更温暖的生长季节。虽然温度升高可能会增加光合作用活性并导致生殖发育提前，但由于土壤含水量减少，产量不一定会增加。这将引起光合作用的光抑制，从而降低光合作用速率、植物生长和种子产量。最近的研究结果表明，在高于正常温度的小麦植株上施用fin - m1可能会增加叶片叶绿素积累。此外，在高于正常温度下生长的冬小麦而不是春小麦，用IN-M1处理的种子产量增加了40%！inucor希望证实in - m1产物、茎部光合作用和籽粒产量之间的联系，以应对与全球变暖有关的高于正常生长温度的反应。该公司预计，拟议的研究将提供蓝图信息，然后可用于设计新的细菌土壤生物刺激剂，以提高高温和干旱胁迫作物的产量，这将有可能使加拿大农业受益。

Inocucor Technologies Inc. (Inocucor) is a Canadian company specializing in the development of sustainableplant-microbial agricultural products. Healthy soils include proliferating communities of plantgrowth-promoting bacteria which contribute to higher crop yields. Therefore, enriching soils with the beneficialbacterial communities and treating plants with biostimulants represent products provided by Inocucor. TheCompany's 1st generation IN-M1 product is currently on sale in 22 US states for high value produce and theCompany's 2nd generation product is registered in 15 states for row crops. Since global temperatures are on therise, Canadian farmers have been experiencing warmer than usual growth seasons. Although warmertemperatures may increase photosynthetic activity and cause earlier reproductive development, the yield willnot necessarily increase due to reduced soil water content. This will induce photoinhibition of photosynthesiswhich reduces rates of photosynthesis, plant growth and seed yield. Recent results indicated that application ofIN-M1 to wheat plants grown at higher than normal temperatures likely increases leaf chlorophyllaccumulation. Furthermore, winter but not spring wheat plants grown at higher than normal temperatures andtreated with IN-M1 had increased seed yield by up to 40%! Inocucor would like to confirm the link betweenIN-M1 product, shoot photosynthesis and grain yield in response to higher than normal growth temperaturespredicted to be associated with global warming. The company expects that the proposed research will provide ablueprint information that can then be used to design new bacterial soil biostimulants to improve the yield ofheat and drought stressed crops that will have the potential to benefit Canadian agriculture.
