Correlation analysis
As can be seen from table 13, the correlation analysis of the main quality index of tomato shows that there is a significant correlation among not only total phenols, flavonoids, lycopene and vitamin C, but also soluble proteins and 4 active substances, wherein the total phenols and flavonoids, soluble proteins and lycopene reach very significant levels. The soluble sugar and the titratable acid have a significant correlation with the soluble solids, while the soluble solids and the soluble sugar reach very significant levels. Studies have also found that the correlation of zinc with iron and flavor content also reaches significant levels, where zinc is very significantly correlated with iron.
TABLE 13 correlation analysis of iron zinc selenium formulation on tomato fruit quality
Principal component analysis
As can be seen from table 14, the cumulative contribution rates of the main components 1, 2, and 3 reached 86.50%, indicating that the first 3 main components can represent all information on fruit quality. The contribution rate of the main component 1 is 47.60%, wherein the main components are soluble sugar, soluble protein, total phenol and flavonoid, which shows that the nutrition quality of the tomato fruit is mainly photosynthetic product and the active substance is the next; the contribution rate of the 2 nd main component is 24.25%, and the main components are determined to be Fe and Zn elements, so that the importance of the mineral element content in the fruit quality is reflected; the contribution rate of the main component 3 is 14.65%, the free amino acid and the single fruit quality are the main components, and the single fruit quality can reflect the appearance quality of fruits to a certain extent, and further influence the internal nutritional components.
Table 14 feature vector, feature root, and cumulative contribution of principal components
As shown in table 15, the analysis of principal component scores of the fruit quality of the iron-zinc-selenium compound treatment revealed that exogenous iron, zinc and selenium all improved tomato fruit quality. The total score is from high to low: se (R) +Zn (L) > Zn (R) +Fe (L) > Zn (L) > Fe (L) > Zn (R) > Se (R) +Fe (L) > Se (R) > CK.
TABLE 15 principal component score analysis of iron zinc selenium formulation on fruit quality
The following conclusions were drawn by the above experiments:
1. the photosynthesis rate of leaves is improved by singly applying and distributing Fe, zn and Se, and the tomato fruit is obviously increased in the transverse and longitudinal diameters, wherein zinc-Fe interaction is more beneficial to plantsIs based on 0.1 g.L -1 The zinc fertilizer can obviously improve the weight of single fruits.
2. Spraying Fe and Zn on leaf surfaces to obviously increase the activities of total phenols, flavonoids, lycopene, vitamin C, POD and CAT in fruits; on the basis of the base fertilizer of Zn and Se, the content of active substances in fruits sprayed with Fe and Zn fertilizers and the activity of antioxidant enzymes are improved to different degrees. In combination, zn (L) and Zn (R) +Fe (L) treatment has better antioxidation effect on tomato fruits.
3. The foliar spray of Fe and Zn and the basal spray of Zn and Se have obvious promotion effect on quality indexes in tomato fruits. On the basis of applying Zn fertilizer, the soluble sugar, soluble protein, sugar acid ratio and the like in fruits are obviously increased by spraying Fe on leaf surfaces. On the basis of the basal Se fertilizer, the indexes such as soluble solids, soluble protein content, sugar acid ratio and the like in fruits are obviously improved by spraying Zn on the leaf surfaces; spraying Fe on leaf surfaces causes more soluble solids, soluble sugars and titratable acids to accumulate in the fruit, but the free amino acid content is significantly reduced. In conclusion, the quality improvement of tomato fruits is obvious by treating Zn (L), zn (R) +Fe (L) and Se (R) +Zn (L).
4. Besides the base Se fertilizer, the reducing sugar and the sucrose content in the treated tomato fruits are obviously increased. Shan Shitie, zinc and selenium all improve the activity of AI and NI in fruits, promote the decomposition and unloading of sucrose, and improve the content of reducing sugar. Both SS, SPS, AI and NI activities were significantly enhanced for zinc-iron formulations compared to the base Zn. Under the base Se fertilizer, the exogenous spraying of Zn and Fe can obviously enhance the SS activity in fruits, obviously reduce the SPS, AI and NI activities, promote the synthesis of sucrose and inhibit the decomposition of sucrose, and is more beneficial to the accumulation of sucrose.
5. Exogenous iron and selenium increase sweet amino acid and essential amino acid content and E/T, E/N in tomato fruits. On the basis of Zn base application, the leaf surface is sprayed with Fe to obviously increase the content of total amino acid and delicious amino acid, but reduce the content of essential amino acid. Based on Se, zn and Fe fertilizers are sprayed on leaf surfaces, so that total amino acid, essential amino acid, delicious amino acid and sweet amino acid are all obviously reduced.
6. Exogenous iron, zinc and selenium can improve the content and the type of flavor substances in tomato fruits; the zinc-iron, selenium-zinc and selenium-iron compound treatment is more beneficial to the improvement of volatile flavor substances, improves the flavor quality of tomatoes, and has the most obvious treatment effect by Zn (R) +Fe (L).
In conclusion, the analysis result of the main component shows that the exogenous iron, zinc and selenium have remarkable promotion effect on the growth and development of tomato fruits and the improvement of nutritional quality, and particularly the zinc-iron and selenium-zinc compound treatment is obvious. Therefore, the tomato cultivation method can effectively improve the nutritive value of tomato fruits and makes a contribution to the cultivation road of tomatoes.
