Effect of Salicylic Acid on Pear Leaf Induced Resistance to Pear Ring Rot

To reveal the mechanism of resistance of pear against ring rot induced by SA, the influence of SA treatment on disease severity and plant defense enzymes were studied with Pyrus bretschneideri cv. Yali and Physalospora piricola Nose as the materials. It is interesting to note that the resistance of pear to P. piricola could be greatly increased by the treatment of 0.2 mM SA. In the present stud...

Toxicity Assessment of SiO2 Nanoparticles to Pear Seedlings

To date, the effects of nanoparticles on woody plants remain unaddressed. This study reveals some of the physiological and biochemical effects of SiO2 nanoparticles on wild pear seedlings. The seedlings were irrigated with different concentrations of nano silica (0, 10, 100, 500 and 1000 mg/l) for 14 days. Nanoparticle adsorption and absorption, biomass allocation, gas exchange, relative water ...

Relative attractiveness of colour traps to pear psylla in relation to seasonal changes in pear phenology

Monitoring of pear psylla (Cacopsylla pyricola (Förster), Hemiptera: Psyllidae) prior to spring bud break could aid in predicting the size of subsequent spring populations and lead to improved proactive management decisions. Yellow traps are commonly used to monitor hemipteran pests including pear psylla, but very little is known regarding seasonal changes in attractiveness of yellow traps or r...

Prickly pear

But events that followed after came and stopped me in my tracks And our talks of authenticity had me thinking back Life isn’t always funny when we’re in the here and now An...
