2024/11/11 9:25:02 ventricular number > First inflorescence segment > second inflorescence segment, soluble solid content > fruit transverse diameter, stalk length, first inflorescence segment, third inflorescence segment > fruit longitudinal diameter > plant height > fruit weight > stem diameter > average number of fruits per inflorescence.The results of correlation analysis showed that the transverse diameter of fruit was positively correlated with pulp thickness and single fruit weight of 28 materials. The soluble solid content was significantly negatively correlated with fruit diameter and fruit weight.The correlation between average number of fruit set per inflorescence, transverse diameter of fruit, stalk length, ventricular number and longitudinal diameter of fruit were the main evaluation factors of cherry tomato, and the cumulative contribution rate was 77.46%.By cluster analysis, 28 tested cherry tomato varieties were divided into 4 groups at 3.0 Euclidene distance. Group 1 was mainly large fruit type cherry tomato, with the largest single fruit mass, thick peel and few single inflorescence fruit sets. The second group mainly consisted of medium-fruit cherry tomatoes with large single fruit weight. The third group was small-fruit cherry tomatoes, which had the smallest single fruit weight and the highest soluble solid content. At 1.5 Euclidean distance, the fourth group can be divided into 3 subgroups, with high soluble solid content and high average fruit set number per inflorescence, including 21 materials.【Conclusion】In this experiment, cherry tomato varieties with strong disease resistance, strong crack resistance, high uniformity and good taste were selected as YTH-FQ-06, YTH-FQ-07, YTH-FQ-09, YTH-FQ-11, YTH-FQ-12, YTH-FQ-18 and YTH-FQ-24, with a total of 7 parts. Most phenotypic characters of 28 cherry tomato varieties showed the same rule in correlation analysis and cluster analysis.]]> 2023/11/16 16:36:08 2023/11/16 16:35:46 2023/10/31 15:39:09 2023/10/31 15:38:18 2023/10/25 8:44:02 2023/10/25 8:43:19 2023/10/25 8:42:52 2023/10/25 8:42:38 2023/10/25 8:38:22 2023/10/25 8:37:59 2023/10/25 8:36:47 2023/8/14 16:34:56 2023/8/14 16:34:37 2023/8/14 16:34:28 2023/8/14 16:34:20 2023/7/6 10:02:33 aboveground. The accumulation of phosphorus in the leaves of T.microphylla showed underground > aboveground at low salinity. The accumulation of nitrogen and phosphorus in Terminalia microphylla was higher than that in Buxus sinica. When the salinity was 0‰, 2.5‰, 5‰, 7.5‰, 10‰, 15‰, 20‰, the amount of nitrogen and phosphorus absorbed by the leaves were 1.83 mg/g, 2.01 mg/g, 1.78 mg/g, 1.91 mg/g, 1.95 mg/g, 1.35 mg/g and 1.68 mg/g, respectively. With the increase of salinity, the accumulation of K+ fluctuated greatly, while the accumulation of Na+ showed an increasing trend. When the salinity > 2.5 ‰, the accumulation of Na+ showed the rule of aboveground > underground, and the increase of Na+ accumulation reduced the ability of plants to remove nitrogen and phosphorus. ( 3 ) pH, ORP, DO and other environmental factors have a certain effect on the removal of pollutants from water and the absorption of nitrogen, phosphorus, K+ and Na+ by plants.]]> 2023/7/6 10:02:22 2023/7/6 10:00:05 2023/5/10 15:11:58 2023/5/10 15:00:47 2023/5/10 14:56:23 2023/2/4 13:13:54 2021/8/17 8:28:26 2020/7/22 16:38:10 2020/5/6 10:43:39 2020/4/8 19:17:40 2019/2/22 15:25:45 2016/11/29 11:23:22 2016/11/29 11:22:56 2016/11/29 11:22:29 2016/11/29 11:21:49 2016/11/29 10:50:39
