“The experience with BioValue have given Ellegaard considerable experience and knowledge on the prospects of stem propagation”

The Project

Ellegaard’s objective was to develop a new method for establishment of sugar cane, sorghum and giant miscanthus. This through using the Ellepot system for stem propagation in which paper pots are used for a more resource efficient sprouting. If successful less plant material will be needed for re-planting e.g. sugar cane fields every 5th year, fields with more evenly distributed plants will render higher biomass yield and mechanical planting will be possible.

The innovation project was within BioValue project 1: To optimize land management, logistics, biomass harvesting and storage.

Results

The main conclusions for each of the three species were:

Sugar cane: It was possible to reach the target of 85 % sprouting after 31 days even in the small pots.

Sorghum: The target of 85 % sprouting was not reached for sorghum. It is concluded from the experiments that mother plants need to be older than 27 days.

Miscanthus: Acceptable sprouting percentages were achieved (38 – 97 %).

The experiments with Ellepot show that this pot type is superior to plastic pots when producing seedlings, simply because the paper pot offers protection to the root of the seedling.

Industrial and Societal Results

For Ellegaard the project provided very useful information on three main issues:

          • Chip size to provide sprouting
          • Quality of cane raw material during storage
          • Ellepot is once again confirmed to hold an advantage against plastic containers, tubes or trays. This is vital for the customer choice of which system to use.

Companies developing new varieties of sugar cane could be the initial users of this propagation system. Today’s propagation of a new variety clones using tissue culture is more expensive and time consuming. Using the Ellepot chip system can provide a faster way to propagate new variety clones for the commercial market.

The report from University of Copenhagen will be used by Ellegaard for marketing purposes and Ellegaard will use the results to inspire customers to test the Ellepot system.

The fact that Ellepot chip system does work for sorghum and some varieties of miscanthus is interesting and useful information for Ellegaard. It could expand business opportunities using the Ellepot system in new applications.

Project Spin-off

One of the major players in the Brazilian sugar cane industry is currently testing the new propagation system using Ellepot.

University of Copenhagen and Ellegaard have started a collaboration with Prof. Dr. Gaspar H. Korndörfer, in Brazil in order to continue the innovation project under tropical conditions.
