Abstract: Tomato is a crop sensitive to water deficit and the responses of seeds germination under these conditions involve biochemical, physiological, molecular processes. The aim this study was evaluate physical, biochemical changes in tomato osmoprimed with selenium (Se) subjected during germination. LA 4050 3475 accessions were PEG 6000 solution (-1.0 MPa) plus Na2SeO4 (12.5 μM) or only for...

Pharmaceutical aviailability of diclofenac sodium from solid dispersions of PEG 6000 have been studied in comparison to those of the corresponding physical mixtures and pure diclofenac sodium. The diclofenac sodium is poorly water soluble drug. The properties of diclofenac sodium-PEG 6000 solid dispersions have been determined by the methods of differential scanning calorimetry (DSC), X-ray dif...

This study was designed to determine the effect of exogenous spermidine (Spd) (30 μM) on white clover seed germination under water stress induced by polyethylene glycol 6000. Use of seed priming with Spd improved seed germination percentage, germination vigor, germination index, root viability and length, and shortened mean germination time under different water stress conditions. Seedling fres...

One of the methods for achieving more yields is to use seed priming technique correctly. When it comes to using seed priming, practically important issues should be taken into account including interval between priming to planting and conditions for storage of primed seeds. Thus, it is very crucial to be informed of duration and temperature for storage of primed seeds. This research seeks to co...

Seed is a fundamental tool to carry out breeding processes and for the propagation of crops; however, seed generally has low irregular germination. Passion fruit (Passiflora) species are economically important Ecuador, which main exporter passion concentrate in Latin America. Ecuadorian farmers propagate new plants by seeds establish orchards or extend their cultivated area. The objective this ...

The aerobic and anaerobic biodegradation of polyethylene glycols (PEGs) in a model wastewater was investigated employing sludge microbes from Xiamen Terylene plant. The effect of molecular weight (MW) on the aerobic/anaerobic biodegradation of PEGs was assessed by performing shake flasks/sealed flasks experiments, respectively, using organic model wastewater containing PEG 600, 6000 and 20,000....

The article presents a comparative description of the effect metabolically active substances and their compositions on individual physiological biochemical parameters soft wheat in drought conditions. study involved use 7 options for seed treatment: control (untreated seeds + distilled water); vitamin E solution (10-8M) - E; ubiquinone-10 Q; methionine (0.001%) M; paraoxybenzoic acid (PОBA) P; ...

Rice being the major food crop for more than half of world population is severely affected by drought stress starting from establishment seedling. We focused on UV-B priming mediated transgenerational tolerance a drought-tolerant rice variety (Vaisakh) towards polyethylene glycol (PEG) 6,000 (20%)-induced drought. Results showed that in F0 generation and re-priming F1 with enhanced PEG potentia...
