The author observed a significant number of "flower face" symptoms on the upper part of tomatoes in the greenhouse at Li Kongming's farm, located in Zhaojiazhuang Village, Gucheng Street, Shouguang City. These blemishes, which resemble flower-like patterns, are a common issue among tomato growers and can affect both the appearance and market value of the fruit. The author believes that several factors contribute to this problem and suggests that farmers take proactive measures to prevent it.
First, the occurrence of "flower face" is closely related to the variety of tomato being grown. Different cultivars have varying levels of resistance to this condition. For instance, the Dahong 1420 variety tends to show fewer "flower face" symptoms compared to the 73-45 variety. Choosing the right seed type is an essential first step in managing this issue.
Second, nutritional imbalances play a major role. Excessive nitrogen, combined with deficiencies in phosphorus, potassium, and boron, can lead to the development of these blemishes. When there's too much nitrogen, chlorophyll production increases, which suppresses lycopene formation, resulting in yellow or green spots on the fruit surface. A lack of boron and potassium can also impair nutrient transport, leading to necrotic areas that turn brown. Additionally, if the plants experience early aging during the later growth stages, the fruits may not develop properly, showing uneven coloration and patches. To address this, it is recommended that farmers use organic fertilizers as a base for their crops to ensure balanced nutrition.
Third, temperature fluctuations significantly impact the development of "flower face." If the fruit surface temperature exceeds 32°C, lycopene synthesis is hindered, causing the skin to remain green or develop brown patches. On the other hand, temperatures below 8°C can disrupt the process entirely, preventing the fruit from turning red. Moreover, high night temperatures increase respiration rates, reducing nutrient accumulation and affecting fruit quality. Therefore, maintaining daytime temperatures between 25–30°C and nighttime temperatures between 13–17°C is crucial for healthy tomato development.
Fourth, light and water management are also key factors. Light intensity directly affects photosynthesis and, consequently, the color development of the fruit. Too much or too little light can lead to irregular pigmentation. Similarly, dry soil conditions increase transpiration, putting stress on the roots and limiting nutrient uptake, which results in poor fruit coloring. Farmers should prune the plants to improve air circulation and light penetration, but they should avoid direct sunlight on the fruit by keeping at least one leaf above each tomato. Watering should be done carefully, only when the soil is dry, to prevent root damage and maintain proper hydration.
By addressing these factors—variety selection, balanced nutrition, temperature control, and proper light and water management—farmers can significantly reduce the occurrence of "flower face" and improve the overall quality of their tomato harvests.
