“…In contrast, cucumber seedlings exposed to low root-temperature (12˚C) had significantly higher soluble sugar content than those at 20˚C [28]. Raising or lowering root-zone temperature altered the synthesis and accumulation of several alkaloids differently in Catharanthus roseus and Nicotiana tabacum [29]. Interestingly, the changes in alkaloid accumulation were observed within 2 days of treatment [29].…”

“…Although poorly studied in carrots, root-zone temperature is an important factor for the production of various plant metabolites in many plants [27]- [29]. In African snake tomato (Trichosanthes cucumerina L.), amounts of phenolics, ascorbic acid, and chlorophylls increased with increasing root-zone temperature [27].…”

“…Raising or lowering root-zone temperature altered the synthesis and accumulation of several alkaloids differently in Catharanthus roseus and Nicotiana tabacum [29]. Interestingly, the changes in alkaloid accumulation were observed within 2 days of treatment [29]. In our study, high-temperature treatment of the root zone for 14 days increased the production of phenolic compounds and soluble solid contents, but also led to suppression of growth in hydroponically grown carrots (Figure 1, Figure 2, Table 1, and Table 2).…”

Air and soil temperatures strongly influence the growth and quality of crops. However, in root vegetables, such as carrot, few experiments aimed at regulating growth and quality by manipulating root-zone temperature have been reported. We investigated the effect of root-zone temperatures (20˚C, 25˚C, 29˚C, and 33˚C) on carrot growth and components using a hydroponic system. High root-zone temperatures for 14 days reduced shoot and rootgrowth and water content. In contrast, total phenolic compounds and soluble-solid content increased in tap roots under high-temperature treatment. Root oxygen consumption was upregulated after 7 days under high-temperature treatment. These results suggest that high root-zone temperatures induce drought-like stress responses that modulate carrot biomass and components. High root-zone temperature treatments administered to hydroponically grown crops may be a valuable tool for improving and increasing the quality and value of crops.

“…While the air temperature is one of the most important environmental elements for the altering secondary metabolism in the plants for production (Kaplan et al, 2004;Zobayed et al, 2005;Ramakrishna & Ravishankar, 2011), the temperature at the root-zone also influences the growth and chemical composition of many plants (Adebooye et al, 2010;Malik et al, 2013;Yan et al, 2013;Sakamoto & Suzuki, 2015a, 2015b. One of the characteristics of hydroponic cultivation is its ability to control the temperature of the nutrient solution around the root system using heaters or cooling spirals, to increase or decrease the temperature, respectively.…”

Optimum cool root zone temperature positively influences the production of greenhouse vegetables grown during summer/high temperature period under hydroponics system. Hence, the effect of root-zone temperature was investigated on the growth, yield and nutrient uptake of cucumber (Cucumis sativus L.) plants grown in pots filled with perlite medium under recirculating hydroponic system in greenhouse during summer period (June-August) in two consecutive years 2016/2017 and 2017/2018 using three cooling treatments-T1 (22 ºC), T2 (25 ºC) and T3 (28 ºC) and non-cooled treatment T4 (33 ºC) as control in Randomized Complete Design (RCD). All the treatments received the same nutrient concentrations. Significant (p < 0.05) differences were observed for all the characters viz. plant height, leaf number/m2, chlorophyll content, leaf area (cm2), fruit number /m2, yield (t/gh), fresh (g) and dry matter weight (g) of shoot and root at all cooled root-zone temperatures as compared to control in both the years. Plants at cooled root-zone temperature (RZT) of 22 ºC gave high number of fruits/m2 to the extent of 180 in 2016/2017 and 220 in 2017/2018 followed by that at 25 ºC (167, 221) and 28 ºC (178, 143) as compared to those in control (33 ºC) (101,133) in both the years. Similarly, highest fruit yields were found at cooled RZT of 22 ºC (5.0 t/gh) and 28 ºC (4.7 t/gh) in the first year and 22 ºC (6.1 t/gh) and 25 ºC (6.0 t/gh) in the second year. The plants at cooled RZT responded positively and significantly (p < 0.05) in the uptake of all nutrient elements in shoots and roots in comparison with those at non-cooled RZT in both years.
