Method for guiding sales strategy of loquat fruits by evaluating and predicting quality of loquat fruits

A method of transporting loquat fruits for sale by evaluating and predicting quality of the loquat fruits, comprising the following steps:

• step 1:
• randomly selecting X samples from a batch of loquat fruits, and sequentially numbering the X samples as 1, 2, 3, . . . , X;
• step 2:
• cutting a j-th sample along an equatorial plane, removing half of the fruit and a core, freezing and slicing, staining with phloroglucinol, calculating a number Nj of lignified cells in an entire slice of the equatorial plane, calculating a total area Sj of the equatorial plane of pulp, and calculating a lignified cell density on the equatorial plane as Pj=Nj/Sj;
• step 3:
• calculating a radius Rji and an equivalent cell wall thickness Dji of the Nj lignified cells of the j-th sample, 1≤i≤Nj, and calculating a lignification trend value of the j-th sample,

• step 4:
• setting a threshold P′ of the lignified cell density, calculating a number X′ of samples with Pj<P′, and calculating a qualified rate Q=X′/X of the batch of loquat fruits;
• step 5:
• setting a qualified rate threshold Q′ and when Q≥Q′, the batch of loquat fruits is qualified, and proceeding with the following steps;
• step 6:
• calculating an average lignified cell density P=Σj=1X(Pj/X) and an average lignification trend value T=Σj=1X(Tj/X) of the batch of loquat fruits;
• step 7:
• grading the batch of loquat fruits according to the average lignification trend value, T, ordering one or more batches of loquat fruits from lowest to highest T values and processing the one of more batches of loquat fruits in order of lowest to highest T values to maximize overall shelf life;
• setting a transportation strategy based on T for a length of time the loquat fruits are transportable;
• and
• transporting, based on T, the one or more batches of loquat fruits for 5-10 days when T>0.9 or for 2-5 days when 0.7<T≤0.9 to another producing area for sale before the one or more batches of loquat fruits perish, thereby preventing waste.
