How plants survive adversity

How plants survive adversity

Preface

Fertilization provides nutrients to crops, enhancing their quality and yield. However, to achieve these benefits, fertilization must be timely (aligned with the crop's growth stages), appropriate in amount (within the crop’s absorption capacity), and suitable (different crops require different types and amounts of fertilizer). When the soil dries out and white or crystalline salt crusts appear on the surface, it indicates an excessively high salt concentration in the soil. This phenomenon is particularly common in controlled environment cultivation systems with over-fertilization and a lack of natural leaching. Furthermore, excessive soil salinity can affect ion exchange, the physical properties of the soil, and pH levels, thereby reducing nutrient uptake efficiency and directly impacting crop growth. 

Adverse conditions for plants also include the effects of ultraviolet (UV) radiation. Increased UV exposure can cause many negative effects on plant growth. Farmers are concerned whether the rise in UV levels will affect crop yields. Taking tomatoes as an example, test results show that UV radiation causes significant damage to tomato plants. The following experiment is a study on how tomato plants grow under salt stress and UV stress. The test results are as follows:

Effect of Saline Stress on Damage Severity in Tomato Plants

Test Method
Tomato plants were cultivated in a growth chamber for 20 days at a temperature of 26°C with 12 hours of light exposure. Different products were applied during this period. After 9 days, a 300 mM sodium chloride solution was administered, and the degree of damage was assessed 3 hours later using a grading system.

Products Used:

• 0.2% Nano Calcium
• 500X DIAMOND QUANTUM –Meily Calcium
• HS1 Microbial Soil Transplant Agent

Statistical analysis was performed using SPSS software with ANOVA, followed by Duncan’s multiple range test. The letterb indicates a statistically significant difference (p < 0.05).

The observations are as follows:

DIAMOND QUANTUM Products Provide Protective Effects for Tomato Plants Under Saline Stress

Observations showed that the application of 0.2% nano calcium, 500X DIAMOND QUANTUM –Meily Calcium, and the combination of 500X DIAMOND QUANTUM –Meily Calcium with HS1 significantly reduced damage to tomato plants caused by salt stress, greatly enhancing plant protection and survival rates.

Effect of UV Stress on Damage Severity in Tomato Plants

Tomato plants were cultivated in a growth chamber for 20 days at a temperature of 26°C with 12 hours of light exposure, during which different products were applied. On the 9th day, the plants were subjected to ultraviolet treatment with UV-C 253.7 nm for 30 minutes. Damage severity was assessed 24 hours later using a grading system.

Products Used:

• 0.2% Nano Calcium
• 500X DIAMOND QUANTUM Brand – Meli-Cal
• HS1 Microbial Soil Transplant Agent

Statistical analysis was performed using SPSS software with ANOVA, followed by Duncan’s multiple range test. The letterb indicates a statistically significant difference (p < 0.05).

Observation Groups: 

A. Untreated

B. 0.2% Nano Calcium

C. 500X DIAMOND QUANTUM –Meily Calcium + HS1

DIAMOND QUANTUM Products Provide Protective Effects for Tomato Plants Under UV Stress 

Results indicated that the application of 0.2% nano calcium and the combination of 500X DIAMOND QUANTUM –Meily Calcium with HS1 significantly reduced UV-induced damage in tomato plants, substantially improving plant protection and survival rates.

Conclusion
Tomatoes are one of the most important solanaceous vegetables worldwide, rich in nutrients such as vitamins and lycopene, and hold great utilization value. The study found that the use of 0.2% nano calcium, 500X DIAMOND QUANTUM –Meily Calcium, and the combination of Meily Calcium with HS1 significantly reduced tomato plant damage caused by both saline and UV stress. These treatments effectively mitigate adverse environmental factors, reduce land resource usage, and minimize seedling waste.
