Root tip detoxification and rapid propagation technology of strawberries
A strawberry and root tip technology, applied in plant regeneration, horticulture, horticultural methods, etc., can solve the problems of slow propagation speed of explant differentiation speed, detoxification test tube seedlings, low production of transplanted field, unstable quality of seedlings, etc. Seedling propagation speed and yield increase, pollution rate is low, and the effect of large-scale promotion of high yield

Embodiment 1
[0067] Example 1 Multiplex RT-PCR Simultaneous Rapid Detection of Virus Infection in Strawberry Tissue
[0068] Commissioned the synthesis of Strawberry virus-specific primer pairs with the following nucleotide sequences, and mixed them into two primers of 4 μM for SMoV, 5 μM for SMYEV, 9 μM for SVBV, and 9 μM for SCrV Mixed primer solution with two primer contents of 10 μM:
[0069] SMoV upstream primer P1: 5'-TAACGGTTCACGTCCTAGTCTGAC-3'
[0070] SMoV downstream primer P2: 5'-TCTTGGGCTTGGATCGTCACCTG-3'
[0071] SMYEV upstream primer P3: 5'-GTGTCCTCAATCCAGCCAG-3'
[0072] SMYEV downstream primer P4: 5'-CATGGCACTCATTGGACCTGGG-3'
[0073] SVBV upstream primer P5: 5'-GAATGGGACAATGAAATGAC-3'
