What are the eggplant grafting rootstock varieties?
Eggplant is very common in our daily lives, and its planting area is also very large. When growing eggplant, because eggplant has relatively poor disease resistance, it is prone to various diseases that affect its growth. Therefore, many people now reduce diseases by grafting eggplant. However, when grafting eggplant, the choice of rootstock is very important. So below, the editor has brought you eggplant grafting rootstock varieties. Let's take a look!
1. Red eggplant
Red eggplant is also called red eggplant and flat eggplant. If red eggplant is used as the rootstock, the eggplant plant has relatively strong resistance to fusarium wilt, verticillium wilt, and other diseases. The red eggplant plant has strong root growth ability, thick stems, and compensated internodes. The seeds are similar to pepper seeds, and the germination rate is relatively high. When grafting, cleft grafting or slant grafting is generally the main method used. If red eggplant is used as the rootstock, then the sowing time only needs to be about one week earlier than the scion. Generally, red eggplant is selected as the rootstock in places with mild disease incidence. If there is severe soilborne disease, then red eggplant cannot be used.
2. Thorny eggplant
Thorny eggplant originally belonged to a wild plant of the Solanaceae family. The stems and leaves of the plant have many thorns, hence the name thorny eggplant. Thorny eggplant is mainly used for high resistance to verticillium wilt, and it is very commonly used in northern regions. The thousand-grain weight of thorny eggplant seeds is about 2g, and the seed color is mainly black-red. Its germination rate is also relatively high. After soaking the seeds for one day, they can all germinate in about ten days. However, during its seedling stage, although damping-off is rare, Rhizoctonia rot is prone to occur. Thorny eggplant has strong low-temperature tolerance, so it is suitable for use in autumn. If the seedling stage encounters a high-temperature and high-humidity environment, then water control and seedling squatting work should be done well to avoid excessive growth.
3. Torubamu
Torubamu is an eggplant variety native to Japan. This eggplant rootstock mainly has high resistance or even direct immunity to four soilborne diseases such as bacterial wilt and root-knot nematode. Torubamu's root system is very developed, and the plant's growth vigor is also very strong, with long internodes. However, Torubamu's germination rate is relatively low, and under normal circumstances it is not easy to germinate. It needs to be soaked with gibberellin for 1-2 days, and then variable-temperature germination promotion work should be done well. Seedlings can only emerge after about a week. But after emergence, its growth ability is strong, the eggplant fruit quality is good, the commodity value is high, and the yield is also very considerable.
4. Totosiga eggplant
Totosiga eggplant is a new eggplant grafting variety introduced into China from the United States. It has strong vitality, is easy to germinate, and can be immune to various soilborne diseases. For example, common verticillium wilt, bacterial wilt, and so on. Its growth is also very robust. If this variety is used as the rootstock, then its fruiting period can be extended by about one month. The yield can also be doubled as a result, and it will not affect the quality of the eggplant fruit.
The above is a brief introduction to eggplant grafting rootstock varieties. That is all for today's introduction. This article is for reference only, and I hope it can be helpful to everyone!
