Year 2 week 33 presentation all sorts of cuttings

  1. 1. RHS Level 2 CertificateYear 2 week 33 – All kindsof Cuttings
  2. 2. Learning Objectives1.1 Explain the genetic characteristics of a clone1.2 Identify area of the plant in which new cells are produced1.3 Name the types of stem cuttings.1.4 Describe the propagation of plants using a range of stemcuttings.1.5 Describe the propagation of plants using a range of leafcuttings.1.6 State the environmental requirements for successfulrooting of each of the types of cutting in 1.2, 1.3, 1.4 and1.5.1.7 Describe the equipment required to propagate plants bycuttings.1.8 Describe the aftercare required for plants raised bycuttings.1.9 Take semi-ripe, softwood and leaf cuttings correctly.
  3. 3. What is vegetativereproduction? growing a new plantfrom some part of anexisting plant e.g.strawberry a plant that isproduced in this wayis geneticallyidentical to theoriginal plant – it is aclone
  4. 4. How does it work? Newly produced plantcells contain all thegenetic informationneeded to make a newindividual (totipotent cells) New plant cells are madeby plant meristems They divide under theinfluence of plant growthregulators to become partof plant organs (e.g.roots)
  5. 5. What happens when a cutting istaken? The cutting is taken at aleaf node, or where leafveins join the midrib,there is a large area ofmeristem. The cells divide quicklyand form callus These callus cells divideand become root cells
  6. 6. Health and safety The scalpels are very sharp. Take care whencutting. Some people are allergic to the sap of someplants – use the latex gloves if you are or maybe affected. Do not get the rooting powder on your skin.Use the wet wipes if you do. Do not inhale therooting powder – put the lid on when not inuse.
  7. 7. To take a softwood cutting 1 Chose a side shootfrom the ‘mother’ plantand cut it with thesecateurs just above aleaf node about 10cmfrom the tip Then cut the stem ofthe cutting with thescalpel on the tile justbelow a leaf nodeabout 6-8cm from thetip Remove the lowerleaves with the scalpelso that the cutting hasa length of bare stemand 2-3 sets of leavesat most Dip the base in rootingpowder – carefully
  8. 8. To take a softwood cutting 2 Make a hole in thecompost with adibber or pencil.Insert the cutting intothe hole up to justbelow the bottom setof leaves. Firm the compostround the cuttingwith your fingertipsgently Label
  9. 9. Leaf blade Cuttings Two methods – cut into sections orremove the central mid-rib. Remember that these cuttings have a‘right way up’. Do not touch the cut surfaces. No need for rooting powder Firm contact with the compost isessential.
  10. 10. Leaf Petiole Cuttings Ideal for Saintpaulia ionantha andPeperomia caperata. Do not leave a snag on the parent plantor this will rot. Trim after removal to leave 2.5 – 3cmstalk – longer will not sit well in the tray. Base of the leaf should sit just under thecompost.
  11. 11. Semi Ripe Cuttings Taken from mid-summer to August from thecurrent years growth – starting to harden butnot yet rigid. Flowering shrubs that produce side shootsare ideal subjects. Longer than soft wood cuttings, need rootingpowder and take longer to root.
  12. 12. After care of a cutting To grow a cutting needs the following:•Moisture – control of transpiration andproviding sufficient water is key•Warmth – whilst rooting•Light – but not direct sunlight•Oxygen/Carbon dioxide•Nutrients – but not when first rooting asthey can scorch the root initials
  13. 13. Learning Outcomes1.1 Explain the genetic characteristics of a clone1.2 Identify area of the plant in which new cells are produced1.3 Name the types of stem cuttings.1.4 Describe the propagation of plants using a range of stemcuttings.1.5 Describe the propagation of plants using a range of leafcuttings.1.6 State the environmental requirements for successfulrooting of each of the types of cutting in 1.2, 1.3, 1.4 and 1.5.1.7 Describe the equipment required to propagate plants bycuttings.1.8 Describe the aftercare required for plants raised bycuttings.1.9 Take semi-ripe, softwood and leaf cuttings correctly.
