Thus, strategies for accurate prediction of the shelf life of apples is urgently needed. In each of the three consecutive years from 2016 to 2018, freshly harvested ‘Royal Gala’ apples were stored at 0, 5, 15, and 25°C, respectively. Subsequently, 11 quality attributes were measured at periodic intervals until the end of storage. To screen fewer and more useful indexes, three input datasets were considered: temperature, color value (L*, a*, b*, △E, and C*), weight loss, firmness, titratable acidity, soluble solids content, starch, and reducing ascorbic acid (D1). The key quality attributes were screened by sparse principal component analysis (SPCA) (D2) and correlation analysis (CA) (D3), using shelf life as the output layer of the artificial neural network based on the back propagation (BP ANN) model. The results showed that the correlation coefficients (r) of the predicted and measured shelf life for D1, D2, and D3 were 0.996, 0.997, and 0.993, respectively, while the mean relative errors were 0.071, 0.074, and 0.074, respectively. Meanwhile, the relative percent root mean square (RMS) values were 0.088, 0.092, and 0.112, respectively. The application of SPCA reduced the quality attributes for the input dataset from 12 to 6. Therefore, SPCA-BP ANN was shown to be a useful model for accurate prediction of the postharvest shelf life of ‘Royal Gala’ apples.

Relighting for 4-8 hr at 10 days after transition to short-day conditions increased the length of cut flowers, number of leaves, flower diameter, and fresh weight of flowers compared to the control. The upper leaf area was biggest after relighting for 8 hr than in the other treatments. However, relighting for 4-8 hr was not effective for increasing the number of ray florets and delayed flowering by 6-8 days. The two daminozide treatments at 18 (stage I) and 28 (stage II) days after transition to short-day conditions shortened the length of cut flowers, but number of leaves and fresh weight of cut flowers increased in all other daminozide treatments. The peduncle length was longest in the control and was 2.6-3.2 cm in one treatment with 800 mg·L -1 daminozide and two treatments with 400 and 800 mg·L -1 daminozide regardless of stage. The upper leaf area was the smallest in control and biggest in one treatment with 800 mg·L -1 daminozide at stage I and two treatments with 400 mg·L -1 at stage I and 800 mg·L -1 daminozide at stage II. The flower diameter and fresh weight were greater in daminozide treatments than in the control. The number of ray florets increased by 9-11% in one treatment with 800 mg·L -1 at stage I or 400 mg·L -1 daminozide at stage II but decreased in two treatments of daminozide. The days to flowering were delayed by 2-6 days in daminozide treatments than in control. Therefore, it is suggested that relighting for 8 hr at 10 days and treatment of 800 mg·L -1 daminozide at 18 days after transition to short-day conditions are effective in improving the quality of cut flowers by shortening the peduncle length and increasing the growth of the upper leaf area, the length of cut flowers, and the flower diameter.

Our aim was to analyze the dynamic characteristics of carbohydrate assimilation, transportation, and utilization in different stages of walnut fruit growth and development. The results showed that (1) at 0 h after the feeding, δ 13 C, 13 Camount, and 13 CPCT in sucrose from the leaves were the highest and positively correlated with net photosynthetic rate of leaves (p < 0.05); (2) at 24 h after the feeding, δ 13 C, 13 Camount, and 13 CPCT in sucrose from the carpopodium reached their peak values; (3) δ 13 C, 13 Camount, and 13 CPCT in sucrose from the peel were lower than those of hexose at 48 h after feeding in the fast-growing stage, but they all reached maximum levels in peel sucrose at 48 h after feeding in the oil conversion stage; and (4) the highest δ 13 C, 13 Camount, and 13 CPCT were recorded in all carbohydrates from the seed kernel 48 h after feeding, among which the highest δ 13 C, 13 Camount, and 13 CPCT were recorded in sucrose. These results suggested that sucrose was the main form of carbohydrate assimilation and transportation in walnut fruit, and large amounts of sucrose are accumulated in the peel and in the kernel, where it is also the base for the transformation of oil.
