Last Updated: 2024/11/22, 1. Variety factor eggplant itself contains some special bitter substances, such as solanine glycoside M (C31H51NO12) and so on. The fruit of wild eggplant is usually bitter, but the bitterness is reduced after cultivation and domestication, but it still has a certain content. There are some differences in the content of bitter substances in different varieties, and its content determines the bitterness of eggplant to some extent. Generally speaking, green eggplant is higher than purple eggplant, dwarf eggplant is higher than long eggplant. 2. the influence of environmental factors on the bitter substances in eggplant fruit.

1. Variety factors

Eggplant itself contains some special bitter substances, such as solanine glycoside M (C31H51NO12) and so on. The fruit of wild eggplant is usually bitter, but the bitterness is reduced after cultivation and domestication, but it still has a certain content. There are some differences in the content of bitter substances in different varieties, and its content determines the bitterness of eggplant to some extent. Generally speaking, green eggplant is higher than purple eggplant, dwarf eggplant is higher than long eggplant.

2. The influence of environmental factors.

The amount of bitter substances in eggplant fruit is largely affected by the external environment. Protected cultivation is a kind of anti-environmental cultivation, and it is difficult to achieve the best environment for eggplant growth due to the influence of the current production level.

3. The influence of grafted rootstocks.

In recent years, in order to prevent continuous cropping obstacles, many eggplant seedlings have been grafted in protected areas. Using grafting to raise seedlings can effectively prevent the obstacle of continuous cropping, but if the rootstock is not selected properly, it will affect its quality and sometimes aggravate the bitterness of eggplant.

4. Improper cultivation measures

Eggplant belongs to fruits and vegetables, and its growth needs complete fertilizer, especially when it changes from vegetative growth to reproductive growth, the demand for some mineral elements increases obviously, if nitrogen fertilizer is applied in this period, it is easy to cause the plant to flourish and produce bitterness. In addition, in the process of eggplant cultivation, water supply must be timely, such as the lack of water supply, it will affect the normal physiological and biochemical activities of the plant, hinder the transformation and accumulation of dry matter and the decomposition and release of harmful substances, resulting in thick and hard pericarp, bitter pulp and reduced quality.
