Slide 2: What is a Petiole?
Before we dive into petiole cuttings, let's make sure we understand what a petiole is. A petiole is the stalk that connects a leaf to the stem of a plant

Slide 3: Petiole Cuttings
Petiole cuttings involve taking a cutting that includes the petiole and a portion of the leaf blade. This technique is commonly used for plants with thick petioles

Slide 4: What are Lamina Leaf Cuttings?
Now, let's move on to lamina leaf cuttings. Lamina leaf cuttings involve taking a cutting that includes only the leaf blade itself

Slide 5: Differences Between Petiole and Lamina Leaf Cuttings
The main difference between petiole and lamina leaf cuttings is the inclusion or exclusion of the petiole. Petiole cuttings have both the petiole and leaf blade, while lamina leaf cuttings only have the leaf blade.

Slide 6: Growth Hormones
To stimulate root growth in leaf cuttings, growth hormones are often used. The most commonly used hormones are auxins, such as indole-3-butyric acid (IBA) and naphthaleneacetic acid (NAA).
