Atmospheric CO2 Enrichment, Root Restriction, Photosynthesis, and Dry-matter Partitioning in Subtropical and Tropical Fruit Crops

Photoperiod and growing degree days effect on dry matter partitioning in Jerusalem artichoke

The effect of photoperiod and growing degree days (GDD) on dry matter and dry matter partitioning in Jerusalem artichoke was investigated during 2008-09 and 2009-10. Three Jerusalem artichoke genotypes (CN-52867, JA-89 and HEL-65) were planted in 15 day-intervals between with thirteen different dates (September 20 to March 20) atKhon Kaen University,Thailand. Jerusalem artichoke genotypes ...

Crop Responses to Elevated Carbon Dioxide

Atmospheric carbon dioxide (CO2) concentration has increased from 280 ppm (parts per million, mole fraction basis) in preindustrial times to 370 ppm today. As concentrations of CO2 and other greenhouse gases rise, global temperature is anticipated to increase. Elevated CO2 will improve crop yields due to increased photosynthesis. However, at above-optimum temperatures for reproductive growth pr...

Olive fruit dry matter and oil accumulation in warm environmental conditions

The present study was carried out during 2007, 2008 and 2009 on 6 olive cultivars to investigate the process of oil and dry matter accumulation in response to warm and dry conditions in Dallaho Olive Research Station of SarpoleZehab, Kermanshah province, Iran. Results showed that oil begins to accumulate in the fruit from July, increases gradually through August and reaches its maximum as the f...

Preharvest Factors Influencing Postharvest Quality of Tropical and Subtropical Fruit

Climate/environment Rootstock/scion Planting design Pruning practices Pest management Irrigation Plant growth regulators Plant nutrition The goal for postharvest physiologists, whether they are working in basic or applied research, is to maximize the postharvest quality of horticultural commodities. Quality relates to several factors that can be commodity specific and mean different things to d...
