Abstract:

The paper aims to study the cutting experiment of Passiflora edulis, identify the key factors affecting the cutting effect of P. edulis, and optimize the best combination of cutting treatment, so as to provide references for the cutting propagation of P. edulis. Three factors and three levels orthogonal design were used to study the effects of stem segment location, NAA concentration and cutting matrix on the cutting effect of P. edulis. Queuing score and formula score were used to analyze the survival effect of cutting, and the best combination of treatment groups for cutting propagation of P. edulis was selected. Cutting position had the greatest influence on the survival rate of P. edulis, while NAA concentration and cutting matrix had relatively small influence. The influence on root number and average root diameter was cutting position> cutting matrix> NAA concentration, and the influence on average root length, new vine length and new leaf number was cutting position> NAA concentration> cutting matrix. The results showed that the cutting position was the most important factor affecting the cutting effect of P. edulis, followed by cutting matrix, and the effect of NAA concentration was the least. The best combination for cutting of P. edulis was A2B3C3 treatment. The cutting effect of P. edulis was the best when the middle semi-lignified stem segments were used as cuttings, soaked in 300 mg/L NAA solution for 20 minutes, and peat mixed matrix (peat: yellow soil= 1:1) was used as the cutting medium.
