Seed Rain and Seed Bank Reveal that Seed Limitation Strongly Influences Plant Community Assembly in Grasslands
Dispersal is an important factor in plant community assembly, but assembly studies seldom include information on actual dispersal into communities, i.e. the local propagule pool. The aim of this study was to determine which factors influence plant community assembly by focusing on two phases of the assembly process: the dispersal phase and the establishment phase. At 12 study sites in grazed ex...
متن کاملUltrastructure of the Shoot Apex of Chenopodium Album and Certain Other Seed Plants
The ultrastructure of cells of the vegetative shoot apices is described for Chenopodium album, Kalanchoë blossfeldiana and K. laxiflora, Bryophyllum daigremontianum, Nicotiana rustica, and N. tabacum (Maryland Mammoth), and Ginkgo biloba. A less intensive study was made of the last three listed. The structures and organelles usually associated with meristematic cells were observed: dictyosomes,...
متن کاملextraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds
سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...
Effects of Salt and Water Stress on the Germination of Chenopodium Glaucum L., Seed
Effect of salts (Na2SO4, Na2CO3, MgSO4, NaCl, MgCl2), soil extract and polyethylene glycol (PEG-6000) on the germination of Chenopodium glaucum L., seed was studied. Maximum germination was obtained in distilled water. Germination decreased with increase in salinity. The inhibition of germination by salt solutions was in the order of MgCl2 > Na2SO4 > Na2CO3 > NaCl > Soil extract > MgSO4. Germin...
متن کاملEndozoochorous seed dispersal of plant species in semi-steppe rangelands
During last two decades studies on endozoochorous seed dispersal indicated that a large numbers of plant seeds are potentially dispersed and suceefully germinated via animal dung. However, very little is known about the relative importance of endozoochory in germination success of plant species in semi-steppe rangelands. In this paper we examined dung germinating seed content, seed deposition p...
