A revision of chestnut-leaved oak (Quercus castaneifolia C. A. Mey.; Fagaceae) in Hyrcanian Forests of Iran
Chestnut-leaved oak (Quercus castaneifolia C. A. Mey) is one of the most important native oaks of Iran distributed in the Hyrcanian Forests. The pure and mixed stands of it cover about 6.5% of these forests. The species represents morphological variations which have resulted in the description of several infraspecific taxa by different authors. Eight taxa were recognized as subspecies and varie...
متن کاملthe effects of soil compaction on morphology and biomass variables of chestnut-leaved oak (quercus castaneifolia c.a.m.) in greenhouse situations
the use of heavy machinery in forestry operations such as logging has increased worldwide during the last decades. however, these machines may seriously influence the soil ecosystem as they induce rutting, disturbing the upper soil layers, and soil compaction. severe compaction of soil adversely affects the growth of plants.this study was done by using a penetration resistance experiment in a g...
متن کاملGrowth and biomass distribution of cherrybark oak (Quercus pagoda Raf.) seedlings as influenced by light availability
Cherrybark oak (Quercrrs pagoda Raf.) seedlings were established and raised in the field under four light levels (100%. 53%. 27% or 8% of full sunlight) to study the effects of light availability on their shoot growth, biomass accumulation, and biomass distribution. After two growing seasons, greatest stem growth was observed on seedlings which received intermediate light levels, and this growt...

متن کاملPhotosynthesis and Biomass Allocation in Oak Seedlings Grown under Shade
Northern’ red oak (Quercus rubra L.) (NRO) and white oak (0. alba L.) (WO) acorns were sown into wooden plots and grown under 30 percent shade screen (30 percent S) or 70 percent shade screen (70 percent S). Seedlings grown under full sun were the controls (C). At the end of the first year, the 30 percent S NRO had 30 percent greater seedling dry weight (DW) than C seedlings. No growth differen...
