Squash Harvest Unstored

Data source: Winna Harvey Crop & Food Research Christchurch New Zealand

The purpose of the research was to determine the changes taking place in squash fruit during the maturation and ripening so as to pinpoint the best time to give the best quality at the market place (Japan). The squash is transported to Japan by refrigerated cargo vessels and takes three to four weeks to reach the market. Evaluations were carried out at a stage representing the quality inspection stage prior to export and also at the stage it would reach on arriving at the market place.

The original objectives were to determine which pre-harvest variables contribute to good tasting squash after different periods of storage time. This is determined by whether a measure of acceptability found by categorising each squash as either unacceptable, acceptable or excellent.

The fruit in this dataset were not stored before being measured, so they lack an attribute present in the stored data - the weight of the fruit after storage.

Number of Instances: 52

Attribute Information: 1. site - where fruit is located - enumerated 2. daf - number of days after flowering - enumerated 3. fruit - individual number of the fruit (not unique) - enumerated 4. weight - weight of whole fruit in grams - real 5. pene - penetrometer indicates maturity of fruit at harvest - integer 6. solids_% - a test for dry matter - integer 7. brix - a refactometer measurement used to indicate sweetnes or ripeness of the fruit - integer 8. a - the a coordinate of the HunterLab L a b notation of colour measurement - integer 9. egdd - the heat accumulation above a base of 8c from emergence of the plant to harvest of the fruit - real 10. fgdd - the heat accumulation above a base of 8c from flowering to harvesting - real 11. groundspot_a - the number indicating colour of skin where the fruit rested on the ground - integer 12. glucose - measured in mg/100g of fresh weight - integer 13. fructose - measured in mg/100g of fresh weight - integer 14. sucrose - measured in mg/100g of fresh weight - integer 15. total - measured in mg/100g of fresh weight - integer 16. glucose+fructos - measured in mg/100g of fresh weight - integer 17. starch - measured in mg/100g of fresh weight - integer 18. sweetness - the mean of eight taste panel scores; out of 1500 - integer 19. flavour - the mean of eight taste panel scores; out of 1500 - integer 20. dry/moist - the mean of eight taste panel scores; out of 1500 - integer 21. fibre - the mean of eight taste panel scores; out of 1500 - integer 22. heat_input_emerg - the amount of heat emergence after harvest - real 23. heat_input_flower - the amout of heat input before flowering - real Class: 24. Acceptability - the acceptability of the fruit - enumerated

Class Distribution: ok - 24 not_suitable - 24 excellent - 4
