Effect
Increased heat stress tolerance
Booster treated tomato seedlings, cv. Heinz1706 grown in a growth chamber under different temperatures enhanced plant height significantly under 10 and 35 °C after 7 days of heat, significantly enhanced stem diameter under 35 °C after 7 and 15 days, significantly enhanced the photosynthetic rate, chlorophyll content, above and underground biomass after 15 days of 35 °C heat, but also significantly enhanced underground biomass after 15 days under 10 and 25 °C compared to the untreated control grown under the same temperature conditions.
