Anatomical leaves characteristics of Quercus rubra L. and Quercus robur L. and stand density

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...

Photosynthetic characteristics of Fagus sylvatica and Quercus robur established for stand conversion from Picea abies

Efforts inEurope to convertNorway spruce (Piceaabies) plantations tobroadleaf ormixedbroadleaf-conifer forests could be bolstered by an increased understanding of how artificial regeneration acclimates and functions under a range of Norway spruce stand conditions. We studied foliage characteristics and leaflevel photosynthesis on 7-year-old European beech (Fagus sylvatica) and pedunculate oak (...

Regeneration Patterns of European Oak Species (Quercus petraea (Matt.) Liebl., Quercus robur L.) in Dependence of Environment and Neighborhood

Quercus robur L. (pedunculate oak) and Quercus petraea (Matt.) Liebl. (sessile oak) are two European oak species of great economic and ecological importance. Even though both oaks have wide ecological amplitudes of suitable growing conditions, forests dominated by oaks often fail to regenerate naturally. The regeneration performance of both oak species is assumed to be subject to a variety of v...

Compared sensitivity of seedlings from 3 woody species (Quercus robur L, Quercus rubra L and Fagus silvatica L) to water-logging and associated root hypoxia: effects on water relations and photosynthesis

Three divergent rDNA clusters predate the species divergence in Quercus petraea (Matt.) Liebl. and Quercus robur L.

Quercus petraea and Quercus robur are two closely related oak species that frequently hybridize. We sequenced 70 clones containing the 5.8S and ITS2 regions of ribosomal DNA (rDNA) from these two species and did not detect a species-specific difference. Surprisingly, three divergent (up to 12.6%) rDNA families were identified in both species, indicating that they predate the speciation event. D...
