S-abscisic acid is a plant regulator, also known as abscisic acid. It was named because it was initially believed to promote the shedding of plant leaves. It has effects in multiple developmental stages of plants. In addition to promoting leaf shedding, it also has other effects, such as inhibiting growth, promoting dormancy, promoting potato tuber formation, and plant stress resistance. So how to use S-abscisic acid? What effect does it have on crops?

1. Promote the rooting of cherry rootstock tenderwood cuttings
Naphthalene acetic acid (NAA)
Treat cherry rootstock with 100mg/L of Naphthalene acetic acid (NAA), and the rooting rate of rootstock tenderwood cuttings reaches 88.3%, and the rooting time of cuttings is advanced or shortened.

Plant growth regulators can enhance cell metabolism, promote cell division, and significantly increase the fruit setting rate of jujube trees. Commonly used ones include Gibberellic Acid GA3, 2.4-D, Naphthalene acetic acid (NAA) and Paclobutrazol (Paclo), which have obvious effects on promoting flowering and fruit retention of jujube trees. Gibberellic Acid GA3 is the most widely used in production.

Indole-3-butyric acid (IBA)
From the end of February to mid-March, select the middle and lower sections of annual plants with a length of 10 to 15 cm and a diameter of 0.4 to 0.8 cm as cuttings. Seal the upper incision of the cuttings with wax, and use 5000 mg/L of indole-3-butyric acid (IBA) to dip the Chinese kiwifruit hard branch cuttings in a quick method of immersion for 3 seconds. Then, the cuttings are cultivated in a sterilized sandy soil seedling bed. The cutting survival rate reaches 81g% to 91.9%, and on average, more than 10 roots are produced per cutting. It should be noted that for hard branches, the soil temperature of the seedling bed should be controlled at 19 to 20 degrees during cutting, and it can be adjusted at 21 to 25 degrees after the wound heals.
