Gazania is a very beautiful plant, but its cold hardiness has attracted much attention. It is widely believed that Gazania is not cold-hardy, but in fact, its cold hardiness is not as poor as people imagine. This article will explore the cold hardiness of Gazania and discuss the temperature at which it can survive.

I. Introduction to Gazania
Gazania is an evergreen or semi-evergreen shrub that can grow up to 3 meters in height. It is native to the northeastern region of China, mainly distributed in provinces such as Jilin and Heilongjiang.
II. Research History of Gazania's Cold Hardiness
Research on the cold hardiness of Gazania can be traced back to the 1980s, when researchers, through testing various physiological indicators of Gazania, found that the plant has a certain adaptability to low temperatures.

III. The Effects of Low Temperature on Gazania
The effects of low temperature on Gazania are mainly manifested in the following aspects: 1. The leaf color turns yellow; 2. The leaves lose their luster; 3. The cytoplasmic fluid solidifies.
IV. The Relationship Between Gazania's Cold Hardiness and Its Growing Environment
The cold hardiness of Gazania is closely related to its growing environment. In relatively harsh environments, the cold hardiness of Gazania will be improved to a certain extent.
V. Optimal Growing Temperature for Gazania
The optimal growing temperature for Gazania is between 15°C and 25°C. Within this temperature range, Gazania can fully utilize light energy and water for growth.

VI. Cultivation Techniques for Gazania in Cold Regions
When planting Gazania in cold regions, the following aspects need to be noted: 1. Choose suitable varieties; 2. Apply fertilizer reasonably; 3. Maintain appropriate soil moisture.
VII. At What Temperature Does Gazania Wither
Gazania will wither at temperatures below 0°C. If it continues to grow at this temperature, Gazania will not be able to survive.
VIII. The Mechanism of Low Temperature's Effect on Gazania
The mechanism of low temperature's effect on Gazania is achieved by affecting the fluidity of membrane lipids and the activity of enzymes.
IX. A Comparison of Gazania's Cold Hardiness with Other Plants
Compared to other plants, the cold hardiness of Gazania is relatively strong, but it still cannot adapt to excessively cold environments.
X. Protective Measures for Gazania Under Low Temperature Conditions
To protect the growth of Gazania under low temperature conditions, we can take the following measures: 1. Windproof and cooling; 2. Covering for insulation; 3. Increasing irrigation amount.
XI. The Effect of Low Temperature on the Flowering Period of Gazania
The effect of low temperature on the flowering period of Gazania is significant. Under low temperature conditions, the flowering period of Gazania may advance or be delayed.
XII. The Significance of Research on Gazania's Cold Hardiness
The research on the cold hardiness of Gazania is of great significance. It can not only provide guidance for the cultivation of this plant in cold regions, but also offer a reference for the cold hardiness research of other plants.
XIII. The Effect of Low Temperature on the Growth of Gazania
Low temperature has a significant impact on the growth of Gazania, which is mainly manifested in aspects such as its slowed growth rate and reduced leaf area.
XIV. Physiological Changes in Gazania at Different Temperatures
The physiological changes in Gazania at different temperatures mainly include changes in chlorophyll content, changes in respiration, and changes in enzyme activity.
XV.
Although Gazania may suffer a certain degree of damage under low temperature conditions, its cold hardiness is not poor. In a suitable growing environment, Gazania can grow and reproduce stably. For us, exploring the cold hardiness of Gazania can help us better understand this beautiful plant.
