Vigour was measured using computer-aided analysis of digital images in six seed lots of Impatiens that differed in vigour but retained greater than 86% standard germination. Seed lots that differed in initial seed vigour were selected based on the commercially used Ball Vigour Index and vigour independently assessed using saturated salts accelerated aging tests. Digital images were captured fro...

Staying vigorous throughout the day is important for work related behaviour, subjective well being, and for effective functioning in the family domain. This study examined trait vigour (i.e. a person’s general level of vigour), day specific workload (time pressure, work hours), and recovery resulting from unwinding during leisure time as predictors of day specific vigour as experienced at the e...

Low viability and poor vigour due to seed deterioration are major problems for successful agricultural production. In this experiment, the ability of hydropriming to ameliorate seed deterioration damage was studied in groundnut. Groundnut seeds were subjected to accelerated ageing for 96 hours at 40 °C and then hydroprimed at 25 °C for 6, 12 and 18 hours. Regardless of duration, hydropriming si...

This research explores the relationship between El Niño/Southern Oscillation (ENSO), captured by equatorial PaciŽ c Ocean Sea Surface Temperature (SST), and interannual variation in vegetation vigour in the southeast USA, captured by Advanced Very High Resolution Radiometer (AVHRR) Normalized DiVerence Vegetation Index (NDVI), for the period 1982–1992. The moving average and ‘baseline’ methods ...

Genetic improvement of seed vigour and emergence of yellow-seeded flax (Linum usitatissimum L.) is important to have a good stand establishment, since they are negatively affected by yellow seed colour. This study was conducted to investigate genetic variation, broad-sense heritability and expected genetic response to selection for germination, seed vigour and field emergence. Sixteen genotypes...

Summary The quality and provenance of seed are exceptional importance for the production yield cultivated plants. There numerous tests determination vigour. accelerated ageing test is one most important that provide degree germination preservation longevity in storages. aim this study was to observe effect different methods – organic conventional on vigour maize (variety Rumenka), using test. M...

126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...

This study examined the impact of night shift on six dimensions of mood. The efficacy of a range of personality, behavioural, and social/organizational predictors of these responses was also examined. Thirty-five female student nurses were studied during their first period of night work. ANOVAs indicated that only fatigue-inertia and vigour-activity were significantly affected by night work. Mu...

Extend abstract Introduction: Guava (Psidium guajava L.) is one of the most important fruit crops of tropical and subtropical regions. Guava (Psidium guajava L.) can be propagated by seed, layering, grafting, cutting or tissue culture. Propagation by seed is used for the production of seedlings usable in breeding programs or rootstock production for grafting. Guava seeds germinate poorly and u...
