Leaf Cutting Propagation: Exploring Petiole and Lamina Leaf Techniques

Leaf Cutting Propagation: Exploring Petiole and Lamina Leaf Techniques

Learning Objective

At the end of the lesson, you will be able to understand and differentiate between petiole and lamina leaf cuttings, identify the hormones used for root growth stimulation, explain the importance of sterile equipment, and demonstrate proper aftercare techniques for leaf cuttings.

What do you already know about leaf cutting propagation?

Slide 1: Introduction

Leaf cutting propagation is a popular technique used to propagate plants. Today, we will explore two different leaf cutting techniques: petiole cuttings and lamina leaf cuttings.

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).

Slide 7: Importance of Sterile Equipment

Using sterile equipment is crucial when taking leaf cuttings. Sterile equipment helps reduce the risk of diseases being spread from plant to plant.

Slide 8: Aftercare for Leaf Cuttings

Proper aftercare is essential for the success of leaf cuttings. This includes providing adequate moisture, providing indirect light, and maintaining a suitable temperature.

Slide 9: Reducing Transpiration

Reducing transpiration is crucial to enhance root growth in leaf cuttings. By keeping the cuttings in a propagator, transpiration is minimized, leading to increased root growth.

Slide 10: Increasing Viability of Practical Work

To increase the viability of your practical work, it is important to follow the proper techniques learned. This includes using sterile equipment, applying growth hormones, and providing suitable aftercare.

Slide 11: Summary

In this lesson, we explored two leaf cutting propagation techniques: petiole cuttings and lamina leaf cuttings. We discussed the use of growth hormones, the importance of sterile equipment, and proper aftercare techniques. Remember to reduce transpiration using a propagator for optimal root growth.
