Effect of low RZT has been previously emphasized; Engels and Marschner (1990) found that low root temperatures not only delayed root growth but also reduced the shoot growth of corn plants.…”

“…Baghour and co-workers demonstrated that 23-27 C soil temperature was optimum for the uptake of most essential and some non-essential elements such as aluminum (Al), As, barium (Ba), Cd, nickel (Ni) and lead (Pb) (Baghour et al 2001(Baghour et al , 2002a(Baghour et al , 2002b(Baghour et al , 2002c(Baghour et al , 2003. These studies also showed that RZT < 20 C, considered sub-optimal for most plants (Zhang et al 2008;Adebooye et al 2010), exacerbates growth as well as nutrient uptake.…”

The effects of root-zone temperature (RZT) on the ion uptake, distribution and interactions of 21 (11 essential and 10 non-essential) elements using Lotus japonicus were studied. After acclimation in hydroponics at ambient (25 C) RZT for three weeks, seedlings were exposed to sub-optimal (15 C and 20 C) and ambient RZTs. After one week, plants were harvested and then growth and mineral elements were analyzed. The highest shoot and root biomass was at 25 C and lowest at 15 C RZT. In shoots, the highest concentrations of all elements, except for nickel (Ni), were at 25 C RZT. At lower RZTs, the reductions in concentrations were more evident especially for trace elements and heavy metals. Except for magnesium (Mg), the highest root concentrations were at 15 C RZT for all essential elements. Unlike other non-essential elements, the highest cadmium (Cd) and cobalt (Co) concentrations in roots were at 25 C RZT. The shoot/root ratios of almost all elements were affected by sub-optimal RZTs. Only manganese (Mn) and Co showed increased shoot/root ratio at sub-optimal RZTs; and this ratio decreased for other elements. Nickel in shoots and Mn, Co and Cd in roots tended to be negatively correlated with most other elements (either, essential or non-essential) in each respective organ. The present study showed that RZT significantly changed the ion profile of L. japonicus and suggests possible connection between global warming and phytoaccumulation of heavy metals, especially in temperate regions, since most metals tended to accumulate in shoots at higher RZT.

“…Among the soil factors that influence root growth, temperature is one of the most important due to its strong effect on nutrient uptake and plant growth (Baghour et al, 2003). In this context, one of the main benefits associated with the use of plastic mulches is a higher root zone temperature (Lamont, 2005), which has been effective in increasing the dry matter of roots in broccoli plants (Brassica oleracea L.) (Díaz-Pérez, 2009) and root growth and the accumulated dry matter of the shoots in black currants (Ribes nigrum L.) (Larsson and Jensen, 1996).…”

C. Bonomelli, C. Bonilla, E. Acuña, and P. Artacho. 2012. Seasonal pattern of root growth in relation to shoot phenology and soil temperature in sweet cherry trees (Prunus avium): A preliminary study in central Chile. Cien. Inv. Agr. 39(1): 127-136. The period between flowering and harvest in the sweet cherry (Prunus avium L.) is shorter than most fruit trees; thus, competition for assimilate and nutrients occurs early in the season. To properly supply water and nutrients during this critical period, optimal growth and root development are necessary. To characterize the root growth pattern of cherry trees in relation to shoot growth and phenology, a study was conducted on a 'Bing' cherry orchard on Gisela 6 rootstock at fourth leaf, located in central Chile (34º70' S, 70º43' W). During the 2009-2010 season, the shoot length and fruit diameter were measured on eight trees, and the root length was quantified by installing rhizotrons on two trees. Additionally, a two-tone (black/white) plastic cover was placed in the row over one tree with a rhizotron to analyze the effects of the plastic cover on soil temperature and root growth. The results showed three peaks of root growth during the season. The first peak occurred 43 days after full bloom (DAFB), corresponding to the phenological stages of the fruit turning from green to straw color. This peak occurred at 326 accumulated degree days (ADD) in the soil and 212 ADD in the air. The second peak was observed after harvest at 97 DAFB, when the shoot growth had stopped, and the soil and air had accumulated 932 and 692 degree days, respectively. The third and last peak occurred at 167 DAFB, with 1887 ADD in the soil and 1361 ADD in the air. The plastic cover increased the average soil temperature by approximately 1 °C, thereby increasing the ADD by 105.2 units during the study period. However, this increase was not enough to affect the root growth pattern.

“…The trend in P and K uptake was similar to between both temperature conditions, which mean a constant increase from 4 to 16 WAT and a sharply decrease at late stage, although K uptake in optimal was temporarily declined at 8 to 12 WAT. High temperature affects the rates of uptake of mineral nutrients (Tindall et al, 1990;Baghour et al, 2002;Baghour et al, 2003). In this study, however, the concentrations and uptake of mineral nutrients in whole plants (leaf, stem and fruit) were little affected by temperature.…”

: Plastic film houses are directly associated with increases in plant growth and yield of vegetable crops through a year round cultivation, however, at the same time temperature stresses are one of fates which are difficult to avoid during crop growth. The objective of this study was to examine the translocation and distribution of minerals (N, P, K) and carbohydrates as well as seasonal fluctuation of mineral uptake and carbohydrate production in cucumber plant grown under moderately high temperature. The temperature treatments consisted of 2-layers film houses (optimal temp.) and 3-layers (high temp.). Shoot growth of cucumber plants were linearly increased until 14 weeks after transplanting (WAT) without any significant difference between both temperatures, and the slowdown was observed from 16 WAT. The level of soluble sugar and starch was slightly greater in optimal temperature compared to the high. Cumulative accumulation of soluble sugar was significantly different before and after 12 WAT in both treatments, whereas starch level represented a constant increase. Monthly production of soluble sugar reached the peak between 12 to 16 WAT, and starch peaked between 4 to 8 WAT and 12 to 16 WAT. Total uptake of N, P and K in optimal and high temperature conditions was 18.4g plant -1 and 17.6 for N, 4.7 and 5.1 for P, and 37.7 and 36.2 for K, respectively, and the pattern of monthly N uptake between optimal and high temperatures was greater in early growth stage, whereas was greater in mid growth stage in both P and K. Thus, this study suggests that moderately high temperature influences much greater to photosynthesis and carbohydrate production than plant biomass and mineral uptake. On the basis of the present result, it is required to indentify analysis of respiration rates from plant and soil by constantly increasing temperature conditions and field studies where elevated temperatures are monitored and manipulated.
