It outlines six distinct scoring levels, ranging from Score 1, indicating immature fruit with full starch staining, to Score 6, representing fruit suitable for short-term Controlled Atmosphere (CA) storage. Each score includes a definition of the staining pattern and corresponding guidance for optimal harvest timing and storage life expectancy. This reference is essential for growers to determine the ideal window for long-term, medium-term, and short-term CA storage, ensuring high-quality produce management. The document is adapted from the Australian Apple and Pear Maturity Assessment Manual, serving as a critical field resource for monitoring fruit development and preventing premature or delayed harvesting, thereby maximizing post-harvest quality and market viability for pome fruit agricultural businesses.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/template/","Template",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/template/general/","General",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/template/apple-maturity-testing-starch-pattern-index-chart-granny-smith/566447/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/apple-maturity-testing-starch-pattern-index-chart-granny-smith/566447.png","ImageObject",442,249,{"name":42,"@type":43},"hdkawk","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-22","2026-10-13",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",6,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What
