Native seed catalogue

Griselinia lucida Shining broadleaf | Puka

This guide is based on a literature review. It compiles information from various sources. Different sources may offer varying advice and findings.

Other known names

Akapuka, akakopuka.

Propagation summary

Good germination and seed viability. Uncertainty around long-term storage.

Seed propagation category

Easy.

Geographical distribution

Found widespread in the North Island and limited areas of the South Island.(1) Located in lowland forest in moist, mild temperate parts of New Zealand.(2)

Seed collection

Seed collection occurs in July.(3) Fruits ripen gradually, maintaining a continuous supply of seeds.(3) Each fruit has 1 seed.(1) Seeds can be dispersed by birds.(1)

Seed storage

Seeds stored in moist conditions were overcome by fungi and bacteria, while seeds dried for 4 months do not survive.(2)

Seed dormancy

8 days to first germination.(2)

Pre-sowing treatments

Needs de-pulping (removal of seed from fruit) as in-fruit seeds do not germinate.(2) Remove fleshy exocarp (the fruit’s outer layer of the skin) by repeated washing with tap water.(2)

Seed viability

100% of seeds are viable.(2)

Germination

Germination rate of 100%.(2)

Propagation techniques

Seed needs frequent watering to establish.(2)

Susceptibility to disease and pests

Larvae of fruitworm moth (Heterocrossa gonosemana).(2)

Research opportunities

Seed storage and vegetative propagation needs further investigation.

Information about the native seed profiles

All species names are in the following order: scientific name, common name, and Māori name. Names may vary by region. We have tried to use the most common names across New Zealand.

We have sourced photos from different websites and creators. We have used the images under different licences. These include Public Domain and Creative Commons licenses. For Griselinia lucida, the image details are:

The basis for each seed profile is a literature review carried out by Scion. Te Uru Rākau – New Zealand Forest Service commissioned and worked on the review to produce a native seed catalogue. The full seed catalogue is on the Ministry for Primary Industries (MPI) website.
