“…The similar effects of 26/38°C and 38/38°C treatments on a number of traits including chlorophyll content and grain-fi lling duration are in agreement with the results of other reports (Kuroyanagi and Paulsen, 1988;Xu and Huang, 2000a;Guedira and Paulsen, 2002;Tahir et al, 2003). The high soil temperature (26/38°C) clearly accelerated leaf senescence, decreased the grain-fi lling duration and promoted WSC remobilization.…”

“…The high soil temperature (26/38°C) clearly accelerated leaf senescence, decreased the grain-fi lling duration and promoted WSC remobilization. High soil temperature has been found to infl uence the growth and senescence of shoots of different plant species more strongly than shoot temperature (Kuroyanagi and Paulsen, 1988;Udomprasert et al, 1995;Xu and Huang, 2000a). High soil temperature reportedly reduces the cytokinin supply from the root and signals the transportation of abscisic acid from the root to the shoot (Itai et al, 1973;Zhang et al, 1987;Kuroyanagi and Paulsen, 1988;Udomprasert et al, 1995).…”

Roots also play more important role than shoot in regulating the responses of carbohydrate metabolism to heat stress (Xu and Huang, 2000a). Shoot senescence is induced by the loss of chlorophyll, which in turn, reduces the grain-fi lling duration.…”

“…Soil temperature strongly affects the shoot growth in many species including wheat (Kuroyanagi and Paulsen, 1988;Guedira and Paulsen, 2002), maize (Caers et al, 1985), sorghum (Clarck and Reinhard, 1991), groundnut (Awal and Ikada, 2002;Craufurd et al, 2003) and bentgrass (Agrostis palistris Huds.) (Xu and Huang, 2000a, b). Even high soil temperatures for a short period can signifi cantly reduce photosynthetic activity and both shoot and root growth (Caers et al, 1985;Udomprasert et al, 1995).…”

“…Signifi cant genotypic differences in the response to high soil temperatures were reported in groundnut (Craufurd et al, 2003), radish (Fukuoka and Enomoto, 2001) and bentgrass (Xu and Huang, 2000a, b). However, studies on the genotypic differences in the response of wheat to high soil temperatures are scarce.…”

As with above-ground tissues, plant roots can be subjected to stressful high temperatures that can limit whole-plant function and decrease crop productivity. Further, with impending climate change, the frequency, duration, and severity of root heat stress will increase. In comparison to shoot function, especially photosynthesis, much less is known regarding heat stress and roots. Most previous research on roots and heat stress has been conducted on detached roots or by heating only roots or parts of root systems (but not shoots too) in intact herbaceous plants, and most past studies on intact plants have imposed chronic heat stress, with few examining effects of abrupt heat stress (e.g., heat waves). Importantly, plant responses to heat stress often differ in detached roots or when only roots are heated, compared to plants wherein both shoots and roots (or shoots only) are heated, and responses to chronic and abrupt heat stress can differ. Hence, many past results do not inform as to how natural heat stress often impacts roots in intact plants or do not inform as to the effects of heat waves on roots. Both chronic and abrupt heat stress can decrease root growth and function, including nutrient and water uptake, and studies in which both roots and shoots were heat-stressed indicate that roots are often more sensitive to heat stress than shoots. Heat stress may affect roots both directly and indirectly, and indirect effects likely involve decreases in shoot carbon provided to roots or changes in root water relations driven by increased shoot water demand, which then affect root growth and nutrient uptake. Interactive effects between heat stress and other global environmental change factors (e.g., elevated carbon dioxide, drought) on roots are likely. We conclude that further research on roots and heat stress is strongly warranted.

Despite its popularity as a putting surface in North Carolina, creeping bentgrass (Agrostsis stolonifera L.) is highly susceptible to summer bentgrass decline (SBD) during hot summer months. Cultural practices have been shown to help alleviate the pressure of SBD. The objectives of this study were to detail the impacts of N fertility, soil water content, and hollow-and solid-tine cultivation on creeping bentgrass quality. Cultural treatments included four N rates (97, 195, 293, and 391 kg ha −1 yr −1), four hollow-tine core cultivation programs (6.4 mm diam. tines two times yr −1 , 9.5 mm diam. tines two and three times yr −1 , and a non-cored control), two soil water content levels (low and high), and two summer solid-tine spiking cultivation treatments (spiked and not spiked). Visual turfgrass quality was measured. A N rate greater than 195 kg ha −1 was needed to maintain acceptable turfgrass quality. High soil water content consistently provided better summer turfgrass quality compared to low soil water content conditions. Nitrogen fertility and soil water content interacted where higher levels of both resulted in the best quality ratings. Hollow-core cultivation reduced turfgrass quality at the lower N rates; whereas, solid-tine spiking had no effect on turfgrass quality. Although weather plays a large role in SBD in North Carolina, results from this study show that cultural practices can influence its severity. How to cite this article: Miller GL, Brotherton MA.
