Calophyllum brasiliense is a species native to Brazil and has potential for use in the timber industry, in the reforestation of degraded areas, besides having medicinal properties. Its propagation is mainly by seeds which, depending on their recalcitrant characteristics, leads to difficulty in conservation, due to changes in its physiological potential during storage. Aiming to contribute to th...

It was evaluated the damage caused by Bruchus pisorum on the germination ability of pea forage cultivars. Result of damage in seeds with parasitized larva was a significant decrease of the germination by 16.4% percentage points, the length and weight of primary radicle by 16.8 and 24.5%, the length and weight of plumule by 12.3 and 14.1%, the vigor index of primary radicle and plumule by 32.5 a...

Seeds are valuable sources of carbohydrates, lipids, proteins, fibers, minerals, and vitamins. They provide energy nutrition to germinating seedlings, food humans, feed livestock, feedstocks industry. High-throughput analyses gene expression in crops has identified many candidate genes associated with seed dormancy, longevity, germination, vigor. In this review, we cover the latest research foc...

OBJECTIVE To determine the prevalence of psychological distress and its relationship with academic engagement (absorption, dedication and vigor), sex and degree among students from four public universities. METHOD A non-experimental,comparative correlational, quantitative investigation without intervention. STUDY POPULATION 1840 nursing and physical therapy students. The data collection too...

crops that better tolerate weed competition or preempt resources from weeds may reduce dependence on herbicides and benefit an integrated weed management program. a field trail was conducted to determine the morphophysiological characteristics affecting tolerance and weed suppressive ability of some winter wheat cultivars in competition with rocket. the experimental treatments consisted of eigh...

Vertebrates are remarkable for their ability to select and execute goal-directed actions: motor skills critical for thriving in complex, competitive environments. A key aspect of a motor skill is the ability to execute its component movements over a range of speeds, amplitudes and frequencies (vigor). Recent work has indicated that a subcortical circuit, the basal ganglia, is a critical determi...

Seeds of mung bean (Vigna radiata (L.) R. Wilczek) are subject to loss viability due aging and damage from pulse beetles (or bruchids; Callosobruchus spp.) infestation during storage. We investigated whether seed drying using desiccants hermetic packaging would prevent or ameliorate these consequences Sun-dried seeds at a moisture content 10% were subjected further for 72 h five different desic...
