Apples sweeter, but losing their crunch, study finds
Print Edition
Global warming is causing apples to lose some of their crunch but is also making them sweeter, a study said yesterday.
Analyzing data gathered from 1970 to 2010 at two orchards in Japan, a research team said there was clear evidence climate change was having an effect on apple taste and texture.
“All such changes may have resulted from earlier blooming and higher temperatures” during the growth season, they wrote in the journal Nature Scientific Reports.
Apples are the world’s third most popular fruit with sixty million tons grown annually.
Previous studies had shown global warming was causing apple trees to flower later, and harvests were also affected by changes in rainfall and air temperature.
The orchards used in the study produce the Fuji and Tsugaru apples, the two most popular kinds in the world.
The farms are in Japan’s Nagano and Aomori prefectures, which had seen a mean air temperature rise of 0.31 and 0.34 degrees Celsius, respectively, per decade. The orchards were chosen because there had been no changes in cultivars or management practices for extended periods.
