Pyrethrum is a perennial daisy grown commercially for the insecticide that is extracted from its flowers. In order to evaluate germination and seedling growth of pyrethrum under different temperature and drought stress treatments, an experiment was conducted in seed technology laboratory of Faculty of Agriculture of Islamic Azad University of Isfahan branch in 2018. During this experiment, poly...

to investigate effects of temperature and salinity different levels on germination parameters of german chamomile (matricaria chamomilla), an experiment carried out in complete randomized design as factorial with three replication in department of agronomy, college of agriculture on the university of guilan, in 2014. treatments were including temperature levels (5, 10, 15, 20, 25, 30 and 35 oc)...

In many forage legumes, hard seed coat is the main problem impeding thegermination by preventing water and gases transport in seed. We evaluated theeffects of mechanical scarification, chilling, different seedbeds (peat and sand) andtheir combination on the germination ratio and time of 9 naturally grown legumespecies belonging Lathyrus and Vicia genus. Control seeds showed very lowgermination ...

Nitric oxide (NO) plays essential roles in many biotic and abiotic stresses in plant development procedures, including pollen tube growth. Here, effects of NO on cold stress inhibited pollen germination and tube growth in Camellia sinensis were investigated in vitro. The NO production, NO synthase (NOS)-like activity, cGMP content and proline (Pro) accumulation upon treatment with NO scavenger ...
