Research of the biocide action streptomycete-antagonist metabolites on causative agent bacterial canker tomato and host-plant fertility is actual question. Aim. To determine Streptomyces globisporus 3-1 cyanogenus S136 phytopathogen Clavibacter michiganensis 102 in vitro seed germination, growth yield tomatoes vivo. Methods. Microbiological methods laboratory conditions descriptive-comparative ...

The activation of the nucleolus of primary root cells of Sinapis alba embryos during the first 72 h of germination was monitored by autoradiographic, ultrastructural and microstereological methods. Autoradiographs showed that within 48 h, the nucleolus progressively resumed the capacity to synthesize pre-rRNA molecules at a high rate. In quiescent embryos the nucleolus was small, compact and co...

BACKGROUND AND AIMS The relative importance of pre- and post-germination determinants for recruitment of natural plant communities is rarely explored. An annual plant community on moving sandy land was chosen for a case study. Answers to the following questions were sought: (a) Does recruitment of new individuals within the community of annual plants differ in time and space? (b) Is there spati...

Seed deterioration is an unavoidable process to which seeds of oilseed plant species such as sunflower are especially sensitive. This study aimed determine whether different invigoration techniques can improve the attributes germination in and alleviate effects seed ageing. Both aged non-aged were subjected by pre-soaking with distilled water 3% KH 2 PO 4 for 24 hours at 25°C. Germination perfo...

Salinity is an important problem all over the world. The destructive effect of salinity observed from seed germination stage. In this study, it was aimed to determine on medically Satureja thymbra L., whether pre-treatments are a factor in breaking stress, and level tolerance species. research, firstly, seeds were exposed two (80°C (5 minutes) + 10 ppm GA3 (24 hours), 80°C 100 hours)) then 8 di...

The most important development period in cereal plants is the initial stage, that is, seed germination and early seedling development. Even if barley thought to be a partially salt-tolerant plant, it may severely affected when exposed salinity at developmental periods. Pre-treatment preparation of seeds before sowing have an agriculture. Nano-seed priming treatment new approach used increase ge...

Relevance. Modern plant growing technologies are associated with the use of nanoparticles for pre-sowing seed treatment. The article presents results studying effect treatment Pisum sativum seeds solutions iron and silicon nanooxides on germination, viability yield plants in conditions Southern Ural. Methods. For seeds, SiO 2 Fe 3 O 4 were used at a concentration 10 –2 , –3 –4 mg/l, as well sol...

Magnetic seed treatment is one of the physical pre-sowing seed treatments to enhance the performance of crop plants. In our earlier experiment, we found significant increase in germination and vigour characteristics of maize (Zea mays L.) seeds subjected to magnetic fields. Among various combinations of magnetic field (MF) strength and duration, best results were obtained with MF of 100 mT for ...
