“…Previous research has primarily quantified carotenoids for their potential phytonutrient availability to grazing animals and is limited to forage-type grasses. Further, those reports evaluating turfgrass carotenoids do not speciate different carotenoids and limit reporting to total carotenoids and xanthophylls (Bailey & chen 1988;lee et al 1996). Bell & Danneberger (1999) reported the most extensive results on carotenoids in turfgrass species.…”

Reactive oxygen species (ROS) are highly destructive chemicals within plant systems. Antioxidants are important photoprotective chemicals that guard plants from oxidative stress. Antioxidants can be classified into two groups: enzymatic and non-enzymatic. Of the non-enzymatic antioxidants, carotenoids have received relatively little attention in turfgrass research. However, carotenoids are vital antioxidants for buffering of singlet oxygen, dissipation of excess light energy through nonphotochemical quenching, and harvesting light energy and channeling to the photosystem. Greater emphasis on carotenoids in turfgrass research could provide several benefits. For example, new cultivars could be selected that have improved high light tolerance owing to greater zeaxanthin production. Additionally, xenobiotics could potentially increase carotenoid production, thereby increasing turfgrass survivability under oxidative stress. Previous research indicates turfgrass species have robust carotenoid pool levels comparable to vegetables and herbs consumed for their phytonutrient benefits.

Carotenoids are important photoprotectant and light-harvesting pigments within the photosynthetic apparatus. Little information is available regarding carotenoid physiology in creeping bentgrass (Agrostis stolonifera L.). Research was conducted to investigate relative high and low irradiance adaptation of creeping bentgrass with respect to bcarotene and xanthophyll composition. 'Crenshaw' creeping bentgrass plants were acclimated for 7 d to relative high [47.9 mol m 22 d 21 photosynthetically active radation (PAR)] or low irradiance (4.7 mol m 22 d 21 PAR). After the acclimation period, plants were transferred from high to low (low irradiance treatment) and low to high (high irradiance treatment) irradiance. Clippings were harvested at 0, 24, 72, and 168 h after the acclimation period. Zeaxanthin and antheraxanthin decreased from 5.1 and 3.4 to 0.9 and 0.6 mg 100 g 21 fresh weight (FW), respectively, over 168 h in low irradiance. As the turf adapted to low irradiance, violaxanthin, lutein, and lutein-5,6-epoxide (epoxylutein) increased at 24 h, but levels decreased from 24 to 168 h. Zeaxanthin and antheraxanthin increased in high irradiance, while violaxanthin and b-carotene decreased. Lutein was the predominant carotenoid quantified regardless of irradiance treatment. Cumulative zeaxanthin, antheraxanthin, and violaxanthin increased as a percentage of the total carotenoids as the turfgrass adapted to high irradiance, but decreased in low irradiance. Conversely, neoxanthin and b-carotene decreased in high irradiance and increased in low irradiance. Creeping bentgrass produces carotenoid amounts comparable to other plant species potentially attributable to selection efforts of more stress-tolerant varieties.
