The Effect Of Exogenous Fructose On Creeping Bentgrass Heat ToleranceLong, William Brett 10 December 2010 (has links)
Creeping bentgrass (Agrostis stolonifera) used on golf course putting greens are some of the most intensively managed areas of turf and are subjected to high stress. Heat stress results in lowered photosynthetic efficiency and inadequate sugar production. An exogenous application of fructose could compensate for the lack of sugar being produced. The objectives of this research were to determine the effect of exogenous applications of fructose on heat stressed creeping bentgrass. Field results showed some phytotoxicity with high rates of fructose, while lower rates showed no visible damage compared to an untreated control. Low rates of surfactant resulted in little phytotoxicity, while high surfactant rates showed damage. Fructose had no positive effect on turf quality. A surfactant study was then designed to measure the effect of various surfactants on fructose uptake. This study revealed that as hydrophilic to lipophilic balance increased, absorption of fructose increased.

EFFECTS OF NITROGEN SOURCE AND NITROGEN METABOLISM ON CHLOROSIS IN LEAVES OF ‘SR 7200’ VELVET BENTGRASS (AGROSTIS CANINA L.)Xu, Huasong 16 January 2012 (has links)
Field observations show that velvet bentgrass (Agrostis canina L.) (VB) an alternative species to creeping bentgrass (Agrostis stoloniera L.) (CB) exhibits chlorosis in the leaves at high nitrogen rates. Growth chamber experiments were conducted that compared VB and CB using a hydroponic system. The experiments tested 5%NH4+-N, 45%NH4+-N, 95%NH4+-N and urea N-sources. Chlorosis only occurred in VB at the 95% NH4+-N and 100% urea-N source. Nitrate, nitrite, and ammonium levels in leaves showed ammonium accumulation was positively correlated to chlorosis in VB. Enzyme analysis showed initial glutamine synthetase (GS) activity in roots compared to leaves is higher in CB than in VB, explaining low ammonium levels in leaves of CB. The GS activity in the roots of VB increased after 24 hours of treatment. The results showed that the chlorosis in the leaves of VB is the correlated to ammonium accumulation associated with nitrogen form supplied and GS activity.
