Though different variants of nearest neighbor classifier are reported in the literature for color classification yet no systematic study is reported till-date for its application in fruit quality assessment using surface color. Research has reported the significant improvement in the soluble sugars content for plant growth and its response to abiotic stress via the exogenous application of melatonin Zhao et al 2015 and myo-inositol Hu.

Fruit Material and Sample Processing Fruits of three different species namely peach apple and pear were collected at the commercial harvest stage and subsequently stored at 1 C for two weeks peach or two months apple. 5Apple is one of the most important commercial fruit crops grown worldwide and thus numerous measures have been applied in order to improve the fruit quality in soluble sugars.

High N reduced the contents of soluble sugar and total flavonoids by 1605 and 1901 respectively resulting in poor fruit quality. 10Apple fruit quality was assessed at harvest and after refrigerated 0 to 1 C storage for three months in regular atmosphere ambient oxygen levels and for three and six months in controlled atmosphere 15 to 2 oxygen. Fruit quality is a dynamic concept changing on the basis of the consumer needs and perceptions that reflect sociocultural evolution.

Fruit quality dependi ng on storage time. 8general idea of quality cannot be easily defined due to the large number of parameters contributing to taste and properties of different apple varieties. Proper postharvest cooling and careful attention to handling can prolong the time during which they remain fresh and marketable.

Moreover high N increased the total N and decreased the total C and CN ratio of apple fruits. Materials and Methods 21. Neural network uses orchard data to predict fruit quality after storage.

Temperature and light contribute to several modiﬁcations of external and internal apple quality like red overcolor and dry matter accumulation but also can trigger unwelcome disorders like sunburn. 11Apple fruit quality phenotyping Expert panel Sensory scores Machine measurements Inter-expert differences abstract Most apple breeding programs use a small number of well-experienced assessors or experts to organolepticallyscorethequalityoffruitfromalargenumberofgenotypesAlthoughinstrumentalread-.

Fruit internal ethylene concentrations and. In most of the tropical highland conditions where apple is growing introducing low-chill cultivar is recommended for quality fruit production because these cultivars are easily satisfied by the existing low temperature and able to tolerate temperature fluctuation in most of the highland areas. To gain full benefit from the crop it is important to sustain the quality of the apples until they are delivered to the consumer.

A researcher from Skoltech and his German colleagues have developed a neural network-based classification algorithm that can use data from an apple orchard to predict how well apples will fare in long-term storage. Fruit quality attributes were evaluated at 0 20 30 and 40 days of cold storage.
