In March 2014, a kohlrabi stem rot sample was collected from the cold storage room of Daegwallyong Horticultural Cooperative, Korea. White and fuzzy mycelial growth was observed on the stem, symptomatic of stem rot disease. The pathogen was isolated from the infected stem and cultured on potato dextrose agar for further fungal morphological observation and to confirm its pathogenicity, accordin...

Forest harvesting of increasing intensities is expected to have intensifying impacts on the genetic diversity and population structure of postharvest naturally regenerated stands by affecting the magnitude of evolutionary processes, such as genetic drift, gene flow, mating system, and selection. We have tested this hypothesis for the first time by employing widely distributed boreal white spruc...

A current paradigm in conservation biology is that forest harvest practices that better approximate natural disturbance processes are more likely to conserve biodiversity. We contrasted bird communities in three replicate stands in each of 1, 13–15, and 22–28 yr old forests following wildfire and harvest in north-central Alberta, Canada. Stands were chosen from old (.120 yr) boreal mixedwood fo...

Practices in the citrus industry evolve rapidly to minimize postharvest decay losses, mostly a result of green mold or blue mold, caused by Penicillium digitatum or P. italicum, respectively. Current problems include the continued development of fungicide resistance among these pathogens, and compliance with emerging secondary residue standards and other privatized regulation of production and ...

leaf yellowing is a major problem in postharvest of alstroemeria cut flowers. for delaying of leaf yellowing and increasing flower quality a completely randomized factorial design was carried out on the alstroemeria cut flowers (‘fuji’ cultivar). in this research ethanol (0, 2, 4, 6%), ga3 (0, 50, 100, 150 mg/litre) in two methods (pulse and continuous) were investigated on the flower vese life...

The commercial application potential of hot water treatments against 1-Methylcyclopropane (1-MCP) for maintaining quality fruit in quince (Cydonia oblonga Mill. cv. ‘Eşme’) during long-term regular air storage was investigated. fruits were treated with either at 50 ± 1 °C 3 and 5 min or two different 1-MCP (SmartFreshSM) concentrations (300 ppb 1000 ppb) 12 20 h. Then, all stored 0 temperature,...

Native population of raspberry fruits (Rubus spp) were treated with Methyl Jasmonate (MJ) fumigation and were assayed for the antioxidant capacity, total anthocyanins and postharvest quality after 7 days storage at 4?C. The result of experiment revealed that berries treated with methyl jasmonate (MJ) showed higher antioxidant capacity and total anthocyanins compared to the controled ones (non...

Salicylic acid (SA) is considered to be plant signal molecule that plays a key role in plant growth, development, and defense responses. The physiological mechanism of exogenous SA to affect the senescence of cut lisianthus flowers during vase life was investigated. Fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mM SA and then held at 25◦C up to 12 days. ...

In this study, the effect of melatonin on the postharvest ripening and quality improvement of tomato fruit was carried out. The tomatoes were immersed in exogenous melatonin for 2h, and then the related physiological indicators and the expression of genes during post-harvest life were evaluated. Compared with control check (CK), the 50 µM melatonin treatment significantly increased lycopene lev...
