Embodiment 1

[0054] The rootstock was commercial tomato hybrid Zhongza No. 9, which was sown 20 days before the scion. The scion material comes from the seedlings of the second-grade seed potatoes of Faurit.

[0055] 120 plants were grafted and 116 survived. Grafted plants are colonized in pots. Stolon induction was carried out on the 30th day after grafting. Two treatments were carried out. Treatment A was sprayed with 3 ppm gibberellin, and treatment B was sprayed with 3 ppm gibberellin+1 ppm indole acetic acid. After spraying, the lower part of the plant was wrapped with black plastic cloth. At the same time, a control group without hormone treatment was set up.

[0056] The miniature seed potatoes were harvested 4 weeks after the induction treatment. The average size of the seed potatoes was 2 cm in diameter and the average weight was 6.5 g. Seed potatoes were harvested continuously for 10 weeks, but the high temperature test was forced to stop later. The growth time of each batch...

Embodiment 2

[0060] The rootstocks were the special tomato rootstock variety Guozhen No. 1 and the special eggplant rootstock Tolubamu. The scion variety is Xiabodi material, which comes from cut and germinated commercial potatoes.

[0061] The grafting method is cut grafting, and the survival rate is 30 / 30 for tomato rootstock and 22 / 30 for eggplant rootstock.

[0062] The grafted seedlings were planted in the solar greenhouse land. The stolon / minituber induction treatment was carried out 30 days after the grafted seedlings were planted, and the hormone treatment concentration was 10 ppm of gibberellin+1 ppm of rooting powder (mainly composed of indole butyric acid). followed by blackening treatment.

[0063] The leaves of the grafted plants in the late stage were positive for potato virus PVY and PLRV and showed corresponding symptoms.

[0064] Due to the characteristics of the variety, the harvest index was changed to a length of 4 cm and an average unit weight of 8 grams. The outpu...

Abstract

The invention relates to the technical field of agriculture production, in particular to a method for producing virus-free seed potatoes by grafting potatoes onto other solanaceous plants.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular, the invention relates to a method for producing potato seed potatoes, especially virus-free seed potatoes, by grafting potatoes (Solanum tuberosum) onto other Solanaceae (Solanaceae) plants. Background technique [0002] As the country with the largest potato planting area in the world, China's potato yield per unit area is only about one-third of that of advanced countries such as the Netherlands. The main reason is the reduction in production caused by the virus. Insect pests such as aphids are serious in most potato producing areas in China, and the potato virus diseases caused by them can only be solved by choosing non-toxic potato seed potatoes. [0003] The currently widely used potato virus-free method is to obtain basic seedlings through potato shoot tip culture, and then subculture to obtain a large number of non-toxic tissue-cultured seedlings and use them to produce ...
