ACTIVITIES 2010 – 2013: rules development

Alcea rosea: introduction of sand germination method

Salvia spp.: evaluation of seedlings

Sampling: samples size (Tab. 2a part 3)

Helianthus debilis: to be changed in Helianthus

spp. different from Helianthus annuus?

Felicia heterophylla: introduction of a new species in the Rules



Felicia heterophylla: introduction of a new species in the Rules

- F. heterophylla – Family Asteraceae

- Samples size: to be based on TSW = 1.25 g

- PSD 4 – Asteraceae (to be confirmed)

- Validation of the germination proposed method:

TP; 20-30 C; 4-7-21; prechill & KNO3.

2 lots ready to be distributed

experienced labs willing to participate are welcome!

We need another seed lot We need data We need information



Helianthus debilis: to be changed in Helianthus spp. different from

Helianthus annuus?

Girasoli in giardinoLe specie reperibili senza rocambolesche ricerche internazionali non sono numerose, ma comunque tutte facili da far nascere dai semi

o, in alcuni casi, dai tuberi. Helianthus debilis è una specie annuale di cui sono offerti in bustina i semi della varietà „Italian White‟,

molto ramificata e con ricca fioritura di corolle di medie dimensioni, a petali bianco avorio con il cuore nerastro. Il già citato H.

grosserratus, gigante perenne della categoria, produce fiori di 5 cm di diametro, ognuno con una ventina di petali gialli; presso gli indiani

d‟America vengono ridotti in poltiglia e usati in impacchi come rimedio alle scottature della pelle. Helianthus hirsutus, perenne, cresce

sino a un paio di metri di altezza e d‟estate si copre di piccoli fiori gialli, come H. laetiflorus, H. strumosus, H. occidentalis (che ha

virtù antibiotiche) e il nordamericano H. tuberosus, il topinambur, tanto allegro nel giardino naturale di fine estate quanto infestante degli

ambienti umidi italiani. Se coltivato nell‟orto, ogni anno in autunno i suoi rizomi tondeggianti e bitorzoluti vanno estirpat i e cucinati in umido per

arricchire di sapore la

tavola di stagione. Ci sono poi alcune specie perenni con la vegetazione ricoperta da un denso feltro biancastro, che conferisce alle piante un

aspetto morbido e vellutato; tra queste si segnalano H. maximilliannii (3 m di altezza, foglie lunghe 30 cm, fiori a centro giallo scuro di 10

cm di diametro) e H. mollis, che produce piante alte al massimo 1,20 m e fiori a numerosissimi petali giallo scuro cangiante.

H. annuus Autumn Beauty

A beautiful sunflower, wonderful for cutting. Many 15cm

flowers in brilliant red, gold, yellow, rust and burgundy.

Blooms over several months. Makes a wonderful display.

Tall, 2m plants.



Helianthus debilis: to be changed in Helianthus spp. different from

Helianthus annuus?

- which species is/are marketed as “ornamental sunflower”

- may we identify the different species by the seed?

We need seeds of the different species We need information



Sampling: samples size (Table 2a part3)

Subject:

Submitted sample/purity sample sizes: multiplication factor between 3 and 50

For many species, the actual purity sample size is not in accordance with TSW

Samples size for flower species needs to be checked and likely changed.

Problems:

Data - We need more data on TSW

Seed size - For many flower species, we have varieties with very different

seed size. (e.g. Cyclamen spp. TSW from 4 to 12 g)

OSD – It is rarely requested, but sometimes it is




Possible actions:

- Collecting data

- Taking decisions:

base the purity sample size on the largest TSW (largest variety or

subspecies)? On an average?

base the submitted sample size on the purity sample size (e.g. 2X,

as it is for some species in table 2A part 1, e.g. Cucurbita spp.),

adding a general rule such as “when the OSD is requested, the

submitted sample must weight at least 5 times the weight listed in

column 2 of table 2A part 3”.
