In order to explore the mechanism of delayed and uneven germination in sharp tooth oak (Quercus aliena var. acuteserrata) (STO), mechanical scarification techniques were used to study STO root and shoot germination and growth. The techniques used were: removing cup scar (RS), removing the pericarp (RP), and cutting off 1/2 (HC) and 2/3 (TC) cotyledons. Germination percentage and root and shoot ...

Pioneer plants are adapted to grow in unpredictable environments. These plants have evolved several traits related to seed morphology and germination to cope with this unpredictability. The main aim of this study was to investigate the effect of plant identity and maternal environment on seed mass and germination of Sinapis arvensis. This study was undertaken with S. arvensis plants grown in fo...

kochia (kochia scoparia l. schard) is an annual, halophyte and drought resistant plant that can be irrigated with saline water and a valuable source for forage under drought and saline ecosystem. in order to evaluate the germination characteristic of kochia under different temperatures and salinity stress levels, an experiment was conducted at physiology lab of ferdowsi university of mashhad, i...

Pollen germination of Vitis vinifera L., of the family Vitaceae was examined in fresh and stored pollen upto 48 weeks at different temperature i.e., refrigerator (+4C), freezer (-20C, -30C) and freeze drier (-60C). Pollen stored at low temperature showed better germination percentage as compared to pollen stored at +4C and fresh. Freeze dried pollen (-60C) showed the highest germination percent...

The genus Thymus is perennial medicinal plants belong to the Lamiaceae familythat is used for different propose in pharmaceutical industry. Environmental stresses,particularly salinity, are considered as the major factor reducing plant growth. The purpose ofthis study was to investigate the effects of salt stress on germination characteristics andseedling morphology in two medicinal species of ...

Seed priming, as a low-cost method, is a technique commonly used to increase germination percentage especially under unfavorable conditions. The objective of this study was to evaluate the effects of bio-priming on the germination of canola (Brassica napus L.) seeds under saline (NaCl) conditions. Seeds of canola var. Hyola 401 were inoculated with plant growth-promoting microorganism (PGPM) in...

environmental stresses, such as salinity can play an important role in disturbing different stages of plant growth, development, and especially seed germination in arid and semiarid regions in iran. turf grasses are highly dissipation in areas associated with saline soils and/or saline irrigation water. in order to study the effects of salinity on turf grasses germination, an experiment was con...

In this study, Ceratonia siliqua L. carob seeds harvested from both wild and cultivated genotypes in Turkey were subjected to mechanical scarification, soaking in hot water and dipping in sulfuric acid. All treatments hastened seed germination and seedling growth of carob compared to control. The germination percentage of control seeds were similar for both wild and cultivated genotypes (13%) a...
