Photinia is a genus of Photinia in the rose family. The branches and leaves of heather in spring are flaming red and have high ornamental value. They can be planted alone in parks, courtyards, streets and other locations, and can be built into curtain walls and hedgerows, which are loved by the general public. In THE process OF transplanting cuttings, in order to ensure the high survival rate of cuttings, it is necessary to use rooting agent before cutting to promote the rapid rooting of cuttings.

Naphthalene acetic acid has been successfully verified in a variety of crops, and Photinia is a difficult plant to root. In order to understand the effect of naphthalene acetic acid on the cutting rooting of Photinia, the crop technical team of Zhengshi Chemical conducted a demonstration experiment on the cutting rooting of Photinia in Rizhao City, Shandong Province in May 2019.

Effect of α-Naphthalene Acetic Acid(NAA) and its combination on cutting rooting of Photinia

Test time and place: Jufeng Town, Rizhao city, Shandong province, May 13rd, 2019

Varieties: Photinia

Test Product: Kuai ShenggenIBANAAHao BeiliNAAYi ShenggenIBANAA

Test Method: After diluting different multiples, heather was dipped into the root of the diluted agent for 5s and 15s, respectively, and then cultivated and managed, and the rooting effect was observed after 30 days.

Test Result: The rooting effect was the best with Kuai Shenggen of 5s dipping and Hao Beili of 800-1600ppm and 5-15s dipping.

5s root dipping effect for Photinia

Cause less photinia X cutting rooting, the main reason for the slow may be improper selection and use of improper, rooting agent and cuttings of scientific management is quite important, there are mainly for prevention and control of plant diseases and insect pests in combination with spraying on the leaf fertilizer or low concentration of water soluble fertilizer, promote the healthy growth, cuttage seedling ensure cutting seedlings of success.
