“…Cattani et al (1996) also found similar stolon and internode lengths between Southshore and Penncross in greenhouse and fi eld trials. Cattani (1999) also reported a correlation between internode and stolon length between 'Emerald' and UM67-10, the parental germplasm of '18th Green'. The cultivars 007, Independence, Alister, LS-44, and Bengal had the shortest mean stolon and internode lengths.…”

“…Our results indicate that cultivars of creeping bentgrass possess varying establishment rates and that Penncross had a greater capability for lateral spread compared with recently developed cultivars. Research has shown that tiller density also aff ects the success of creeping bentgrass competing with annual bluegrass (Beard et al, 2001) but shoot density is negatively related to internode length (Cattani, 1999). These fi ndings indicate that internode length is an important morphological characteristic infl uencing the lateral spread of creeping bentgrass cultivars.…”

“…Plants with lower CGR values tend to have higher LAR and SLA (Patton et al, 2007). Previous work has demonstrated that a high density creeping bentgrass allowed for an increase in tiller development at an earlier stage in development compared with a low density bentgrass (Cattani, 1999). Individual leaf blades of recently developed cultivars of creeping bentgrass such as Bengal tend to be narrower compared with Penncross (Croce et al, 1998).…”

“…The most recently developed cultivars of creeping bentgrass tend to possess more upright growth, fi ner textured leaf blades, and increased tiller densities compared with Penncross and are more tolerant of traffi c and heat and drought stress (Croce et al, 1993;Sifers and Beard, 1997;Toubakaris and McCarty, 2000). However, some researchers and turf practitioners believe the proliferation in the number of tillers and resulting shorter internodes may decrease the lateral spread of creeping bentgrass (Cattani, 1999). A benefi t of more tillers per unit area is greater resistance to invasion from annual bluegrass (Poa annua L.) (Croce et al, 1998).…”

Creeping bentgrass (Agrostis stolonifera L.) cultivars are available that possess varying vegetative characteristics. A better understanding of the vegetative growth among creeping bentgrass cultivars is essential to its culture and would aid breeders in selecting for improved turf characteristics in germplasm screening programs. Our objectives were to identify differences in establishment rates among cultivars of creeping bentgrass and to determine the factors associated with differing growth rates by using growth analysis techniques. Spaced plantings of 24 cultivars of creeping bentgrass were evaluated for stolon characteristics and lateral spread. Two cultivars with differing lateral spread were used for further growth analysis in a growth chamber. ‘Penncross’ exhibited greater lateral spread and longer internodes compared with recently developed cultivars. ‘Bengal’ had the slowest lateral spread and the shortest mean stolon and internode length. Internode and stolon length were positively correlated as well as internode length and establishment rate indicating that cultivars with long internodes also possess fast establishment rates and longer stolons. Growth analysis indicated that Penncross and Bengal produce similar amounts of dry matter but Penncross allocates more dry matter into stolons than leaves. Variation in dry matter partitioning could partially explain differences in lateral spread among cultivars of creeping bentgrass. The vegetative characteristics should be matched with desired site usage requirements for optimum performance when selecting cultivars of creeping bentgrass.

Cattani, D. J. 2003. Divergent selection for flowering in annual bluegrass and its impact on plant development and turfgrass utility. Can. J. Plant Sci. 83: 157-162. Annual bluegrass (Poa annua L.) is a widely occurring turfgrass component. Recent efforts to develop cultivars of this species have led to increased interest in selection methods. The objectives of this study were to evaluate the utility of controlled growth studies for divergent selection for flowering and to evaluate the resultant selections for development and turfgrass quality. Two growth cabinet selection runs (1997 and 1998) were made at a constant 20°C and a 16-h photoperiod at low light levels. Selection was based upon the earliest and latest plants to produce a seedhead on the main stem. In the second selection run, mid-flowering selection was made to characterize the population distribution. Selections were grown out in the greenhouse in 1998 and 1999. Selections made in 1998 were seeded into a field study in August 1999 and maintained as golf green turf. Late selections flowered later than early or mid selections and produced more leaves on the main stem prior to inflorescence appearance. Seedhead ripening showed greater uniformity in late selections. Some late selections produced few seedheads under the greenhouse conditions. Selection for divergent flowering types was successful using the method employed. Turf performance was not related to flowering type, indicating that screening for turf performance will be required after initial selection for plant type.Key words: Poa annua L., selection, life history, tillering, seed production, turf performance Cattani, D. J. 2003. Sélection divergente du pâturin annuel pour la floraison et incidence sur le développement de la plante et son utilité pour la production de gazon. Can. J. Plant Sci. 83: 157-162. Le pâturin annuel (Poa annua L.) fait souvent partie des essences utilisées pour la production de gazon. Les efforts déployés pour créer des cultivars de cette espèce ont récemment ravivé l'intérêt pour les méthodes de sélection. L'étude devait établir l'utilité des essais de croissance contrôlés en vue d'une sélection divergente pour la floraison et permettre l'évaluation des variétés sélectionnées en fonction de leur développement et de leur qualité pour la production de gazon. À cette fin, l'auteur a procédé à deux séries de sélections en chambre de croissance (1997 et 1998). Les plantes étaient cultivées à une température stable de 20°C, avec une photopériode de 16 h, sous un faible éclairage. On a sélectionné les premières et les dernières plantes à produire une panicule sur la tige principale. La deuxième série de sélections portait sur le milieu de la floraison et devait établir la distribution de la population. Les variétés sélectionnées ont été cultivées en serre en 1998 et 1999. Les graines des plantes sélectionnées en 1998 ont été semées en pleine terre en août 1999 et les parcelles ont été entretenues comme pour la production de pelouse de terrain de golf.

Heat injury in creeping bentgrass (Agrostis stolonifera var. palustris Huds) has been associated with decreases in carbohydrate availability. Extending light duration may increase carbohydrate availability and thus improve growth of creeping bentgrass under heat stress. The objective of this study was to investigate whether turf performance and carbohydrate status could be improved by extending daily light duration for creeping bentgrass exposed to supraoptimal temperature conditions. `Penncross' plants were initially grown in growth chambers set at a day/night temperature of 20/15 °C and 14-hour photoperiod and then exposed to a day/night temperature of 33/28 °C (heat stress) and three different light durations: 14 (control), 18, and 22 hours (extended light duration) for 30 days. Turf quality and tiller density decreased with the duration of heat stress, as compared to the initial level at 20 °C, regardless of the light duration. However, both parameters increased with extended light duration from 14 to 18 or 22 hours. Extended light duration, particularly to 22 hours, also improved canopy net photosynthetic rate from -1.26 to 0.39 μmol·m-2·s-1 and daily total amount of carbon assimilation from -6.4 to 31.0 mmol·m-2·d-1, but reduced daily total amount of carbon loss or consumption to 50% through dark respiration compared to 14 hours treatment by the end of experiment. In addition, extending light duration from 14 to 22 hours increased water-soluble carbohydrate content in leaves both at the end of light duration and the dark period. These results demonstrated that extending light duration improved turf performance of creeping bentgrass under heat stress, as manifested by the increased tiller density and turf quality. This could be related to the increased carbohydrate production and accumulation. Supplemental lighting could be used to improve performance if creeping bentgrass is suffering from heat stress.
