The quality parameters were investigated in strawberry fruit using soilless cultivation under the tropical greenhouse production. The soilless strawberry production using substrate and NFT system was compared with soil cultivation and they were cultivated using standard nutrient solution with an electrical conductivity 2 mS cm-1 for all. Objectives of the studies were to investigate characterize the quality of soilless cultivated strawberries under tropical greenhouse and to identify the comparison between the color skin of strawberry that measurements using chromameter and digital image processing. The quality parameters, consist of fresh weight, size, texture of skin, soluble solids, total acidity, ascorbic acid, and anthocyanin values, were determined destructively using standard method. The color skin of strawberry fruit were determined non-destructively using the chromameter and digital image processing, then result between these measurement values were compared statistically. Based on results, the strawberry fruit grown in soilless cultivation systems under tropical greenhouse had bigger and better fresh weight, size and crop yield (in NFT soilless cultivation only) compared to soil cultivation in physical quality, and nutrition quality had higher values of soluble solids, ascorbic acid, L* and a*, while total acidity and anthocyanin fruit values were higher in soil cultivation. On the other hand, the comparisons of values the color skin of strawberry that measured between chromameter with digital image processing was relatively different, through different color specification and conversion method with moderate accuracy. Further research could be considered to improve this image processing method with low cost of the instrument and the ease of use. |
