Transient expression profiles for several chimeric beta-glucuronidase (GUS) gene constructs were determined in tissues (young leaves, mature leaves and roots) of creeping bentgrass (Agrostis palustris, cv. Penn A4) following microprojectile bombardment. The constructs analyzed consisted of the uidA (GUS) reporter gene driven by four different promoters (ubiquitin 3-potato, ubiquitin corn, ubiqu...

Dr. Atsushi Miyawaki, who is said to be the pioneer of turfgrass research in Japan, returned from studying at Kansas State University a part-time lectureship Hokkaido 1911, beginning 110 yr study Japan. Professor Miyawaki's original area was actually manufacturing dairy produce, however, while America, he became fascinated by wonderful condition pasturelands there. Alongside his studies, began ...

An essential component of an introductory turfgrass management course is the description of how turfgrass species are adapted to different cultural systems and environments. The objectives of this project were to develop an interactive program to introduce the characteristics of turfgrass species and their optimum environments and to evaluate the students' gain in understanding turf species cha...

Most soil moisture sensor systems (SMSs) marketed for landscape irrigation respond to the dielectric permittivity of the soil. Compared to potable water (PW), reclaimed water (RW) may contain more salts, which can modify the dielectric permittivity of the soil and, hence, alter the readings of SMSs when measuring the soil water content. The main objectives of this experiment were to evaluate th...

Each turfgrass species and cultivar has particular optimal growth requirements. Water, fertility and mowing height differ. Similarly, insect pest management needs vary with grass type. As chemical pest management tools become less available, researchers at the University of Georgia are seeking alternative methods in the management of common turfgrass pests. Their foundation management strategy,...

Potential resistance to the twolined spittlebug, Prosapia bicincta (Say), was evaluated among 56 turfgrass genotypes. Greenhouse, laboratory, and Þeld bioassays identiÞed differences in spittlebug survival and development, host preference and damage levels, and turfgrass tolerance to and ability to recover from pest induced injury. All centipede grasses demonstrated high levels of susceptibilit...

Little is known about the interplay between Ca2+ and H2O2 signaling in stressed cool-season turfgrass. To understand better how Ca2+ and H2O2 signals are integrated to enhance grass acclimation to stress conditions, we analyzed the rearrangements of endogenous ion accumulation, antioxidant systems and secondary metabolism in roots, stems and leaves of perennial ryegrass (Lolium perenne L.) trea...

heavy metal hyperaccumulators have recently attracted considerable attention in remediation of an area's pollutants. lead (pb) is one of the main pollutant heavy metals that its relatively high concentration have been reported in some environments. in present study, the potential of turfgrass tolerance, regarding seed germination and plant establishment were evaluated, in different concent...
