Selecting seeds with high vigour eminently affects initial plant growth and determines stand. Various tests including electrical conductivity (EC), radicle emergence counts (RE), standard germination (SG) were used to assess the of eleven lentils (Lens culinaris L.) seed lots. Lentil lots over 75% normal germination, germinated use an ISTA test. The (2 mm) was tallied at constant intervals from...

Greater early vigour has potential for increasing biomass and grain yields of wheat crops in Mediterranean-type environments. Embryo size is an important determinant of early vigour in barley and likely to contribute to greater vigour in wheat. Little is known of the underlying genetic control for embryo size, or its genetic association with early vigour in wheat. Over 150 doubled-haploid lines...

BACKGROUND AND AIMS Natural and anthropogenic disturbances can act as stresses on tree vigour. According to Manion's conceptual model of tree disease, the initial vigour of trees decreases as a result of predisposing factors that render these trees more vulnerable to severe inciting stresses, stresses that can then cause final vigour decline and subsequent tree death. This tree disease model wa...

Production of high quality seeds in African leafy vegetables has not been practiced due to varying reasons including incorrect harvesting stages and fertilizer rates. Jute mallow (Corchorus olitorius L.) pods do not ripen simultaneously and fruits left to dry on mother plant long before harvesting, which face seed quality deterioration. Timely seed harvesting ensures maximum seed quality attrib...

In plants encouraged by the proliferation of seed, seed to plant survival factor to maintain the role is very vital and important. In order to evaluate different size effect's on the quality seedling production during germination in wheat (Triticum aestivum L.), this experiment was conducted in 2011 at Laboratory Sciences, Islamic Azad University Shahr-e-Qods Branch by a completely randomized d...

Abstract Seed physiology of 15 Eucalyptus species interest for cut foliage plantations was unknown and therefore evaluated. The viability vigour seeds germination potential determined by using a tetrazolium (TZ) staining test, the results were compared to test. In separate experiment, each lot subjected either 0 or 4-week cold stratification at 4 ± 1 °C investigate their requirement. After stra...
