In-vitro plant tissue culture · Val-d'Oise

Healthy plants, multiplied identically.

MICROPLANTES produces healthy, vigorous, true-to-type young plants through micropropagation. More productive, more durable, fully traceable cultures — from the lab to your field.

At full capacity, Microplantes will produce approximately up to 10 million vitroplants per year — making it the largest dedicated plant micropropagation facility in France.

Why in-vitro

Three core benefits.

Tissue culture and meristem cleansing remove viruses and pathogens, producing vigorous and durable cultures with industrial homogeneity — independent of climate.

  • 01

    Healthy plants

    Sanitation eliminates viruses and pathogens, for vigorous and durable cultures.

  • 02

    Consistent quality

    Each plant is a true clone of the mother plant — homogeneous stands.

  • 03

    Year-round availability

    Production planned across the year, independent of climate.

How we work

A 4-step production cycle.

Every plant we ship goes through the same controlled production cycle, from initiation to acclimatation.

  1. 01

    Initiation

    Sterile in-vitro culture of a healthy fragment from a selected mother plant.

  2. 02

    Multiplication

    Proliferation of micro-shoots on controlled nutritive media.

  3. 03

    Rooting

    Root development until a vigorous, autonomous plant is obtained.

  4. 04

    Acclimatation

    Progressive hardening in greenhouse, quality control, and shipment.

Generation by generation, the gap explodes

Each in-vitro subculture splits one shoot clump into several. Three cycles take weeks, not seasons — micropropagation fills a tray while cuttings give a handful.

Copied, not engineered

GMO cuts and inserts DNA. Micropropagation copies the whole plant — chromosomes and all — so the genome is identical to the mother.

Inside a clean lab: a sterile hood for cutting tissue, a lit growth room of culture vessels, then rooting. Out to the greenhouse to acclimatise, and on to growers.

Virus-free, true-to-type

Viruses spread slowly and lag behind the fast-dividing tip. Culturing only the tiny apical dome leaves them behind — giving clean, uniform plants.

Production lines

Four crop families, named varieties.

We focus our expertise on high-value species that propagate well in vitro, with strong and growing European demand.

01

Soft fruits

Fragaria, Rubus, Vaccinium

Soft fruits are highly sensitive to viruses, which accumulate through traditional multiplication. Our sanitised plants restore vigour, yield, and taste.

  • Strawberry — Gariguette, Charlotte, Mara des Bois

    Fragaria × ananassa

    The star of soft fruits. Virus-free vitroplants, rapid establishment, homogeneous fruiting.

  • Raspberry — Heritage, Tulameen

    Rubus idaeus

    Multiplied via axillary buds; vigorous and productive canes.

  • Blueberry — Bluecrop, Duke

    Vaccinium corymbosum

    A "super-fruit" in strong growth — in-vitro is the reference method.

02

Horticulture

Gerbera, Spathiphyllum, Hosta

For ornamentals, in-vitro guarantees homogeneous batches, calibrated and available on demand.

  • Gerbera

    Gerbera jamesonii

    A micropropagation classic; high multiplication rate, uniform flowering.

  • Spathiphyllum

    S. wallisii

    Robust, easy to multiply in large volumes year-round.

  • Hosta

    Hosta spp.

    A prized shade perennial; preserves the variety integrity of premium variegated cultivars.

03

Sweet potato

Ipomoea batatas

A crop in strong European growth, highly sensitive to viruses transmitted through cuttings. Meristem culture produces sanitised planting material — the basis for a yield leap.

  • Beauregard

    Orange flesh

    The fresh-market reference, rich in beta-carotene. Virus-free plant (SPVD).

  • Bonita

    White flesh

    Mild flesh, firm texture appreciated in cooking.

  • Murasaki

    Purple skin

    A trending variety, rich in anthocyanins — premium/organic segment.

04

Date palm

Phoenix dactylifera

A very high-value crop, multiplied via somatic embryogenesis: plants true to the mother, healthy, and homogeneous — indispensable for premium plantations and export.

  • Medjool

    "Queen" date

    Large and soft, among the most valued worldwide.

  • Deglet Nour

    Semi-soft date

    The most exported, fine and translucent — commercial reference.

  • Barhee

    Round date

    Caramelised flavour, eaten fresh; very productive.

Plant formats

From in-vitro plantlets to ready-to-plant material.

We adapt the delivery format to your organisation — whether you're a nursery equipped for acclimatation or a grower looking for ready-to-plant stock.

01Non-rooted vitroplant (stage 2)

Micro-shoots in flasks, for you to root and acclimate in-house. Most economical and flexible format.

For — Nurseries equipped with lab/greenhouse

02Rooted vitroplant (stage 3)

Plant rooted in vitro, ready for acclimatation. Secure establishment.

For — Nurseries & growers

03Acclimated plug (stage 4)

Young plant, hardened in plug, ready to transplant or plant directly.

For — Growers & farms

04Sanitised mother plant

Indexed, virus-free stock, for your own multiplication programs.

For — Breeders & multipliers

FAQ

Common questions from clients and partners.

What is a vitroplant?

A young plant produced by in-vitro culture from a fragment of a selected mother plant. It is healthy and genetically identical to the mother stock.

Are in-vitro plants GMOs?

No. Micropropagation is simply identical vegetative multiplication; it does not modify the plant's genetic makeup.

Why "virus-free" plants?

Viruses accumulate through traditional multiplication and reduce vigour and yield. Sanitation via meristem culture restarts from clean material.

Do you work on small volumes?

Yes. We adapt our services to small as well as large volumes, including research and conservation projects.

Can you multiply my own variety?

Yes, through contract growing and under full confidentiality. A protocol development phase may be needed depending on the species.

What delivery formats?

Non-rooted vitroplants, rooted vitroplants, acclimated plugs, or sanitised mother plants — depending on your organisation.

What are the lead times?

Developing a new protocol can take several months; restocking catalogue varieties is faster. We specify on quote.

Do you ship internationally?

Yes — in compliance with the phytosanitary requirements of destination countries.
