Abstract
Fruit development and traits of loquat (Eriobotrya japonica Dahongpao) were observed in a solar greenhouse in Northern China (N 40°10, E 122°09). The trees were pollinated naturally in 2004 and artificially in 2009. Cumulative growth curves based on fruit diameter displayed a single sigmoid pattern in the two years.
The growth rate curves of both of seasons had two peaks, and the second peak was higher.
In 2010, the average weight per fruit was 41g, the index of fruit shape was 1.04, and there were 3-7 seeds per fruit.
These traits were better than those in 2005. However, the soluble solid content in 2005 was higher than that in 2010, and fruit ripening in 2005 occurred 40-50 d earlier than in 2010. The difference of fruit quality characteristics was related to pollination methods at flowering season.
Therefore, Dahongpao loquat in the solar greenhouse in Northern China should have artificial or bee pollination to insure fruit set and quality.
