Plant growth promoting rhizobacteria (PGPRs) are a group of bacteria that can actively colonize plant roots and can modulate plant growth. The present study was aimed to investigate the effects of three PGPRs strains designated as Pseudomonas fluorescens (PF23) and P. putida (PP-41 and PP-159) on seed germination features including germination percentage (GP), mean time germination (MTG), germi...

ABSTRACT Handroanthus impetiginosus is a Brazilian native tree threatened by illegal logging that needs conservation strategies. Due to the need obtain seeds of high genetic and physiological quality, this study aimed select mother trees, aiming at installation Seed Collection Areas H. impetiginosus. Therefore, diversity quality from 63 individuals natural population in Rio Grande do Norte, Bra...

Seed priming was carried out to determine the effect of different agents on seed germination and growth landraces lentils. The two factorial experiments were in a completely blocked design which one is 7 treatments, i.e., PEG (10%), Boric acid (0.1%), Urea (2%), (5%), DAP CaCO3 (2%) & Control. Other landraces, Sunwarshi-LR1 Rangeli-LR2, collected from locations Morang district, replicated t...

Optimization of seed density range, combined with the use quality seeds may help generate more profit from wheat production, as these factors affect grain yield and seeds. The aim this study was to evaluate effects initial vigor level sowing densities on productive performance plants physiological two cultivars in cultivation environments. experiment carried out cities Londrina Ponta Grossa, Pa...

Seeds with high vigor have strong resistance to various adverse environmental conditions. However, little is known about how seed affects the of seeds biotic stress. In this study, newly harvested that had and low vigor, achieved via an artificially accelerated aging treatment, were used in germination test after inoculation Fusariumgraminearum for 24 h. The results showed high-vigor seed-relat...

Seed priming is a physiological seed enhancement method. Hydroor osmotic priming can advance germination under adequate moisture conditions. During direct seeding on well-drained paddy and upland fields, rice seeds occasionally encounter low soil moisture conditions. Under these conditions, rice seeds need to undergo rapid germination and secure emergence through improved water absorption capac...

The quality of rice seed is very important for production. In the process production, drying an link in whole control, and problems mechanical are factors affecting seed. It easy to encounter rain weather when sterile seeds dried by natural air, which seriously affects vigor. High-quality guarantee achieve high yield rice, germination rate one directly yield. has greatest effect on seeds. Selec...
