Low pre-death growth rates of oak (Quercus robur L.)—Is oak death a long-term process induced by dry years?

Long-term Growth and Persistence of Blue Oak (quercus Douglasii) Seedlings in a California Oak Savanna

We report on growth and survivorship of two cohorts of blue oaks Quercus douglasii Hook. & Arn. (Fagaceae) monitored at Hastings Reservation in Monterey County, California, the first growing in an unprotected old field and measured as seedlings in 1965 and the second planted as acorns in 1985 in several sites differing in their degree of protection from grazing. Growth of all individuals was ex...

Sudden oak death syndrome fells 3 oak species

INTENZITET FOTOSINTEZE I VEGETATIVNI RAST HRASTA LUŽNJAKA (Quercus robur L.) U POKUSNOM NASADU PHOTOSYNTESIS INTENSITY AND VEGETATIVE GROWTH OF PEDUNCULATE OAK (Quercus robur L.) IN COMMON-GARDEN EXPERIMENT

SAŽETAK: U radu je analiziran utjecaj mikrostaništa na fiziološke značajke i vegetativni rast hrasta lužnjaka. Istraživanje je provedeno na dvije pokusne plohe koje se odlikuju različitim kemijskim značajkama, sadržajem vlage i temperaturom tla. Cilj rada bio je utvrditi utjecaj različitih kemijskih značajki tla na vegetativni rast i intenzitet fotosinteze hrasta lužnjaka, kao i odnos koncentra...

Identification and Expression of Nine Oak Aquaporin Genes in the Primary Root Axis of Two Oak Species, Quercus petraea and Quercus robur

Aquaporins (AQPs) belong to the Major Intrinsic Protein family that conducts water and other small solutes across biological membranes. This study aimed to identify and characterize AQP genes in the primary root axis of two oak species, Quercus petraea and Quercus robur. Nine putative AQP genes were cloned, and their expression was profiled in different developmental root zones by real-time PCR...

The destruction of oak by the death-watch beetle.

CERTAIN of the oak timbers of Rothamsted House were recently found to be extensively damaged by wood-boring insects, the damage being ascribed chiefly to the death-watch beetle (Xestobium rufovillosum).' The timbers are believed to be of great age, and some were probably used in an earlier building. In 1623 the house was extensively altered and the exposed timbering of the original house covere...
