Blueberry Fruit Development and Splitting
<p>Rain-related splitting of blueberry fruit is a problem facing growers in the southeastern United States and causes an estimated profit loss of up to 20% ($300- $500 per acre). Studies of this phenomenon in other thin-skinned, soft, fleshy fruit showed that no single or set of related …

Investigating aquaphotomics for fruit quality assessment
… of aquaphotomics were explored for internal fruit quality assessment, such as dry matter (DM) and soluble solid content (SSC) measurement using near infrared spectroscopy (NIRS). Fruits like apple and kiwifruit are more than 80% water. The NIR spectrum of whole intact fruit is dominated by …
