Freeze tolerance differs between two ecotypes of Paspalum vaginatum (Poaceae)
Provedor de dados: 39
Autores: Fabbri,Liliana Teresa; Ploschuk,Edmundo Leonardo; López,María Virginia; Insausti,Pedro; Rua,Gabriel Hugo.
Morphological and physiological responses to freezing were evaluated in two ecotypes of the perennial turfgrass Paspalum
vaginatum. Leaf extension rate, number of active meristems, leaf water potential and net photosynthesis were measured on plants
of both a commercial cultivar, 'Sea Isle 2000', and a wild ecotype from the Flooding Pampa grasslands of Argentina. Plants were
propagated by cloning, cultivated in pots, and examined during 18 consecutive days under two treatments: a non-frozen control
treatment (15.5±7 ºC) and a frozen treatment with two stages: Stage 1 with four hours of freezing stress for 10 nights (-5ºC), and
Stage 2 with 12 hours of freezing stress for eight nights (five nights at -5ºC and three nights at -8ºC). After these treatments,...

Nitrogen-use efficiency and economic efficiency of slow-release N fertilisers applied to irrigated turfs
in a Mediterranean environment
Provedor de dados: 188
Autores: Arrobas, Margarida; Parada, Maria; Magalhães, Paula; Rodrigues, M.A.
The effect of three fertilisers that delay the bioavailability of nitrogen (N) in the soil was compared with ammonium nitrate and a
zero N control in two irrigated turfs in NE Portugal. The fertilisers used were: Floranid permanent 16-7-15 (slow-release,
IBDU/Isodur fertiliser); Basacote plus 9M 16-8-12 (controlled-release fertiliser, copolymer ethylene acrylic); Nitroteck 20-8-10
(stabilized fertiliser, dicyandiamide as nitrification inhibitor + coating with polyterpene) and Nitrolusal (ammonium nitrate, 20.5%
N), applied all at a rate of 120 kg N ha-1. Nitrolusal was split into two fractions of 60 kg N ha-1. Phosphorus (P) and potassium
(K) rates were balanced among treatments by using superphosphate (18% P2O5) and potassium chloride (60% K2O). The...

Dieback foliar y podredumbre seca de grama bahiana ocasionados por Curvularia lunata en
Argentina: (con 4 figuras)
Provedor de dados: 85
Autores: Palmucci,Hemilse E; Amat,Graciela.
Una nueva enfermedad fue observada sobre Grama Bahiana (Axonopus compressus (Swartz) Beauv.) en jardines de la ciudad y
alrededores de Buenos Aires. Se caracterizó por la aparición de dieback foliar y podredumbre seca del cuello, vaina y estolones.
Mediante técnicas fitopatológicas rutinarias fueron aisladas en agar papa glucosado colonias negras aterciopeladas, identificadas
como pertenecientes a Curvularia lunata (Wakk.) Boedijn. Se llevaron a cabo tests de patogenicidad con resultados positivos. Se
concluye que C. lunata es el agente causal de esta enfermedad sobre A. compressus, siendo este el primer informe como patógeno
de esta especie en Argentina.

Competitive Relationship of Three Warm-Season Turfgrass Species
Provedor de dados: 31
Autores: Adrian,
John L., Jr.; Duffy,
Patricia A.; Lloyd,
Michael.
The competitive position of three warm-season turf species commonly grown in the South (bermudagrass, centipedegrass, and
zoysiagrass) is evaluated for a farm with 100 acres available to allocate to turfgrass-sod production. A multiperiod linear
programming model is used to determine optimal mixes of grasses and resulting net returns for a seven-year planning horizon.
Within current observable price ranges, variation in the prices of the different grasses has little impact on the profit-maximizing
combination of grasses. Bermudagrass, with the shorter production cycle and positive influence on cash flow, dominates the
higher-valued, longer-production-cycle alternative grasses. Availability of initial money capital from internal sources does not
alter the...

The Green Industry Today - Some Issues and Future Prospects
Provedor de dados: 31
Autores: Johnson,
Doyle C.; Christensen,
Robert L.
Green industry sales are projected to total $40.4 billion in 1994. The industry ranked sixth in 1991 among farm commodity groups
in total cash receipts, and over the past decade total receipts increased 10 percent per year. Net income per farm is the highest of
all the commodity groups. Nevertheless, the sector has received scant federal support compared to other commodities. In spite of
growth and significance, economic analysis and data availability and reliability have been limited. There is clear justification for
increased efforts in data collection and economic analysis of this industry’s problems.
