河西走廊日光温室甜樱桃方位分布与果实品质关系OA

Taking'Huangmi'and'Meizao'sweet cherry fruits as test materials,fruit physical properties,nutritional content,functional components,mineral element levels,and physiological indicators were measured to investigate the effects of environmental differences across different orientations(east,middle,west)in solar greenhouses on fruit quality for these two varieties,in order to provide references for variety selection and spatial layout optimization in protected cultivation.The results showed that there was a significant interaction between variety and position on fruit quality.'Zaomei'had advantages in firmness,reduced ascorbic acid,β-carotene,and total phenolic content,with the highest firmness on the east side and β-carotene content significantly higher than that of'Huangmi'on the east side;'Huangmi'exhibited a'high sugar and high acid'characteristic,with a higher total sugar content and strong stability,and its flavonoid content was significantly higher in all positions.Among the mineral elements,the calcium content of'Zaomei'was the highest on the west side,and the iron content of'Huangmi'was more advantageous in the middle.In conclusion,'Zaomei'was an environmentally sensitive variety with excellent comprehensive quality,suitable for layout on the east and west sides;'Huangmi'was a variety with strong stability and distinctive flavor characteristics,and had a wider adaptability for cultivation.When actually carrying out the planting,it was necessary to conduct differentiated cultivation based on the characteristics of the varieties and in accordance with the space of the greenhouse.
