Leaf Traits and Photosynthetic Light Response of Quercus Suber L. Seedlings Grown in a Combination of Light and Water Regimes
The aim of this study is to investigate the effects of two important factors: light and water availability on the leaf characteristics and the growth of plants. Seedlings of Quercus suber were grown under controlled conditions (greenhouse) with three light treatments (100, 27 and 3 % of incident light, open, shade and deep shade; respectively) and with daily irrigation. Since middle spring, one...
متن کاملResponses of Quercus Suber Seedlings under Different Light and Water Treatments. Greenhouse and Field Experiments
The objective of this study is to understand the response of Quercus suber seedlings to light and water, two limiting factors of their growth and survival in Mediterranean woody plants. Greenhouse and field experiments were conducted to contrast the results from both types of experiments. At the greenhouse experiment, Quercus suber seedlings were grown at three treatments of light (3%, 27% and ...
متن کاملPhysiological and biochemical responses of Quercus brantii seedlings to water deficit stress
Water shortage is one of the most important environmental stresses in Mediterranean regions. Poor seedling quality may account for the failure of oak regeneration. To determine the best seed origin of Quercus brantii, we investigated on seedlings collected from 20 mother trees in the Zagros Mountain forests 700 to 2200 m altitudes above sea level. Seedlings from different altitudes were irrig...

ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
15 صفحه اولEffects of soil and stem base heating on survival, resprouting and gas exchange of Acer and Quercus seedlings.
Acer rubrum L., A. saccharum Marsh., Quercus alba L. and Q. rubra L. seedlings subjected to soil and stem base heat treatments showed rapid declines in rates of transpiration and photosynthesis. Reductions in photosynthetic rate were partly attributable to mesophyll inhibition. Quercus seedlings were less able to maintain transpiration and photosynthesis after heat treatment than Acer seedlings...
