Extended abstract Introduction: Heavy metals pollution is one of the most important environmental problems. This type of metals with accumulation in the food chain has a lot of human and animal hazards. Among heavy metals, lead is considered to be the most dangerous of heavy metals in the environment, which is contaminated with the environment through the lead-acid battery industry, paint addi...
humic substances as an active part of soil organic maters can improve germination and seedling properties, plant establishment and plant growth. in order to study the effects of different concentrations of humic and fulvic acids on germination and seedling properties of two varieties of triticale (triticosecale hexaploide lart.), a factorial experiment based on a completely randomized design wi...
In order to study the effects of salinity stress on growth indices of three clover species including, Trifolium resupinatum, T. alexandrinum, and T. incarnatum, an experiment was conducted as factorial based on a completely randomized design arrangement with three replications. Factors included seven levels of salinity stress (0, 41, 82, 123, 164, 205, and 246 mM) and three clover species. Diff...
Extended abstract Introduction: Using of plant growth regulators is one of the methods can improve plant growth against environmental stresses such as salinity. Salicylic acid plays an important role in physiological processes regulation, including germination. Today, using of growth promoting bacteria has been increased and it causes to raise the seed vigor, uniformity, germination percentage...
There have been a few studies on removing the seed pods in annual medics, despite its importance. To investigate the role of pod removal on seed germination, seedling growth and antioxidant enzyme activities in annual medic (Medicago scutellata L.) Under salt stress, a factorial experiment was conducted based on a completely randomized design with four replications in 2014. Salinity at 5 levels...
Extended Abstract Introduction: Fenugreek, is a medicinal plant that has been considered as a salt tolerant crop. This research was conducted to investigate the effects of salt stress on seedling emergence characteristics and determination of the salt tolerance threshold, declivity of emergence and salt tolerance index of some fenugreek ecotypes. Material and Methods: Seeds of five ...
Globally, seagrass beds have been recognized as critical yet declining coastal habitats. To mitigate seagrass losses, seagrass restorations have been conducted in worldwide over the past two decades. Seed utilization is considered to be an important approach in seagrass restoration efforts. In this study, we investigated the effects of salinity and temperature on seed germination, seedling esta...
Drought and low water stress is the most important environmental stress which plant are exposed to in low precipitation regions such as southern and central parts of Iran. Milkweed is one of valuable plant species with numerous industrial (producing high quality fibers) and medicinal benefits which has relatively resistance to drought conditions of southern Iran. The present study aimed to inve...
KUMBHAR B. A. AND DABGAR Y. B. Dept. of Biotechnology, Sheth M.N. Science College, Patan (Gujarat) India R.R. Mehta College of Science and C.L. Parikh College of Commerce, Palanpur (Gujarat) India Abstract This study investigated the allelopathic effects of various weed (Euphorbia thiamifolia L.) plant parts on pigeon pea germination and seedling growth. Aqueous extracts of Euphorbia thiamifoli...
seed reserves are controlled by genetic and environmental condition such as nutrition, temperature, drought stress and light intensity. strong seedling will produce from seeds with high reserves. therefore, in this work that conducted in pot, field(in tabriz university) and lab(in shahrood university of technology) experiments, effect of pre-anthesis nitrogen application and a drought stress du...
