Ali imate kakšne izkušnje s sejanjem judeževega drevesa?
Semena bi nabrala v naravi – z drevesa.
Ali je potrebna kakšna predpriprava semena? Ali ga lahko posejem že jeseni, pri kakšni temperaturi kali?

Vsako mnenje ali predlog bo dobrodošel.

Nobene ideje, nihče ne pozna tega drevesa !!??

Tu je še latinsko ime: Cercis siliquastrum

Seed - best sown as soon as it is ripe in a cold frame[200]. Pre-soak stored seed for 24 hours in warm water then cold stratify for 3 months[113]. Sow spring in the greenhouse[78]. As soon as they are large enough to handle, prick the seedlings out into individual pots and grow them on in a greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Plants resent root disturbance and are best planted out in their permanent positions as soon as possible[11]. Cuttings of half-ripe wood, July/August in a frame[200].

Seed Production and Dissemination- Seeds are released by the opening of fruit sutures or decay of the fruit wall. Most seeds are dispersed during fall and winter by wind and animals. Many seeds are injured by insects. Those that fall to the ground usually remain dormant for several years (1).

For artificial propagation, seeds should be collected, cleaned, and dried when ripe to avoid insect damage. Dried seeds can be stored in sealed glass or metal containers at 2' to 5' C (35' to 41° F). Seed treatment is necessary for propagation because redbud shows delayed germination due to impermeability of the seed coat to water and dormancy of the embryo (1). The seed coat can be made permeable to water by mechanical scarification or by immersion in boiling water or in concentrated sulfuric acid for about 30 minutes. After scarifying, seeds should be stratified in moist sand at about 5° C (41' F) for 5 to 8 weeks (14).

Prepared seeds should be sown in well-prepared seedbeds in late April or early May (14). Moist soil should cover seeds at a maximum depth of 0.5 em (0.2 in). Propagation can also be accomplished by layering or cuttings.
