Research about leap in cultivation system started for Zantedeschia

The traditional bulb cultivation system repeatedly reuses their own plant material as starting material, therefore many diseases and pests are taken along in subsequent cultivation. The idea of the PPS Fundamental system leap, is to break through this recirculation of disease, in order to grow bulbs in a cleaner and sustainable way.

We do this by a technological solution in the form of a system leap (one-way cultivation system), where we start with clean material (tissue culture), accelerate their cultivation under protected and optimal conditions, and deliver material that requires only one outdoor growing season. A multiplication step is included in this system, once the bulbs have reached the required size for vegetative propagation. This PPS considers four bulbous crops: tulip, narcissus, Hippeastrum and Zantedeschia. The research on the latter crop has already started this spring.

Research on cultivation and propagation

Growing Zantedeschia tubers under protected conditions brings higher cultivation costs. In order to keep the cultivation profitable, we are investigating two possibilities: increasing the propagation capacity of the tubers (to multiply the material) and shortening the cultivation time. In the first aspect, we are investigating how to partition the tubers in a more efficient way and how to ensure bud outgrowth. Everything with the aim of producing more offspring per tuber.

In order to accelerate the cultivation system, we are looking at the effect of different LED spectra and high EC given on different cultivation moments, both on tuber growth. This is done in the greenhouse with tissue culture material and tuber “chips" (tuber cut in pieces). We expect to find clues on how to accelerate the tuberization process of Zantedeschia without compromising its quality.

PPS Fundamental system leap

The PPP Fundamental System Leap is a four-year research program of the top sector Horticulture & Starting Materials of the Ministry of Agriculture, Nature and Food Quality. Within this project there are four work packages with a focus on tulip, daffodil, Zantedeschia and Hippeastrum.

  1. WP1 – Propagation
  2. WP2 – Physiological research as the bases for the system leap
  3. WP3 – Marker Technology
  4. WP4 – Economy, communicate & project management
The implementation of this Public-Private Partnership lies with a consortium of thirteen partners. These are: KAVB, Anthos, Wageningen University & Research (WUR), Hobaho, Kapiteyn, Prins, Iribov, Dunamo Foundation, Agrifirm-GMN, BQ Support, Greenport Duin & Bollenstreek, Bollenacademie and Rabobank Nederland.
