Se pare ca pot lamuri dilema mea de ieri legata de acest salcam japonez! Am gasit un material dedicat exclusiv salcamului japonez- dar nu prea limba noastra:) [urlnew=]http://www.ces.ncsu.edu/fletcher/programs/nursery/metria/metria04/m45.pdf[/urlnew] Vestile nu sunt prea bune! Din seminte se pare ca salcamul japonez in unele cazuri a inflorit si dupa 25-30 de ani, deci cine a scris pe undeva- 10 ani, eu unul asa am citit, se pare ca a fost generos!
PROPAGATION
When Sophora japonica trees are grown from seed, they generally
do not flower until nearly mature -- sometimes as late
as 25-30 years (Main0 and Howard 1972). This makes sexual
propagation a long-term project. However 'Regent' scholartree
flowers at a much earlier age and presumably other selected
genotypes could also be chosen, in part, for early flowering.
Daca pe paginile de limba romana se vorbeste doar despre altoirea speciei de salcam japonez numita de noi pletoasa sau Pendula stiintific, exista rezultate bune prin altoire si la alte specii de sophora. Butasirea se pare ca da si ea uneori rezultate! Cert este ca denumirea generica folosita de noi aici - Salcamul japonez , daca este sa fim scrupulosi, ar trebui nuantata.!
Sophora japonica has been successfully vegetatively propagated
by a variety of methods, including softwood cuttings,
grafting and layering. The most common cultivar, 'Regent',
is grafted, but Frank Santamourl has suggested it may be susceptible
to latent graft incompatibility.
Un alt material despre inmultirea lui Sophora japonica! Sunt destul de mutle detalii tehnice, care sincer ma depasesc! de pilda inmultirea prin rizosfera(?) Daca cineva ne paote da un echivalent romanesc al acetui material ar fi excelent...

The Golden Bough Sophora japonica(5)
Huang Jinhuai The main breeding methods to tree grafting, high grafting and budding two methods of rhizosphere. High survival rate, growth speed, is a commonly used method of garden nursery stock breeding.
Growth habit
Kimji Kunikihikaru, a little shade, cold resistant, but not shade tolerant, not quite strict to edaphic requirement, also can grow normally in containing lime and mild saline soil.
The first high.
A high grafting method, high grafting with the bark grafting grafting method. This method has the advantages of simple operation, high survival rate. Prior to grafting, selective growth full, no pests, about 1 cm in diameter Annual branches As scions, short cut into 10 cm wax seal, to prevent moisture loss, then sand storage in a cool wind standby.
4 months late, Sophora japonica, stay after germination, selection DBH More than 3 cm, the trunk is straight tree seedlings, grafted in place after cut. The scion is cut into 3 to 5 shoots back cm Planed noodles Surface must be straight, and more than a heart, the back end face cut into 0.5 to 0.8 small bevel P?. Stem in Sophora japonica section, select the smooth and straight place, Sophora japonica cortex vertical cut a small mouth, long length of scion Planed noodles 1/2 to 2/3, the scion along the incision Xylem Insert and phloem, xylem length cut face, and make the scion backside alignment median incision, face "blank" 0.3 to 0.4 cm, according to the Chinese scholartree roughness can be connected with 2 to 3 scion, and is evenly distributed, the scion connected, with 5 centimeters wide plastic cloth, the wound is tied tightly can.
A month after grafting, the survival of the scion can sprout. At the same time the Rootstocks on cryptophyte will germination, formation of sprouting, should be promptly removed, so as not to affect the growth of scion. Because of the scion growth, timely solution to tie, and will shoot tied to the stick, to prevent the wind was bad.
In addition, high grafting of usable also budding, grafting in the main branches of Sophora japonica seedlings, the specific operation reference rhizosphere budding.
Rhizosphere budding
Two, the rhizosphere rhizosphere budding budding root is used with xylem bud. This method has simple operation, high survival rate, fast healing, firm combination, conducive to the growth of seedling grafting advantages, therefore, widely used in growth.
The grafting method
Grafting time was in the spring and autumn season three can be, not leave the skin and not limit. The specific method is:
The 1 annual shoot clipping golden pagoda as scions, remove the leaves aside, because the weather is hot and other reasons, it is best to take with grafted with scions method, so as to avoid the scion. Time is too long, water loss and lower survival rate.
2 from the top branches bud scion 1 to 1.5 cm under the knife, slightly xylem straight down flat cut, to shoot 1.5 to 2 cm, lateral oblique knife remove bud. Then select the diameter of 0.5 cm above the rootstock rootstock, in from the ground 5 cm upwind surface smooth, cut down from a bud length and width section was considerable, the lower transverse oblique knife to remove the chip, then will bud into the stock interface. Planed noodles Aim Cambium Close to the rootstock face. Plastic film thickness of 0.03 cm, 1.2 cm wide strips tied around, all tied tightly wrapped around the wound. If the summer, after 15 days, the application of plastic film shoot near the knife to cut, the buds exposed, in order to make the new shoots out, and check the survival rate, and then welding didn't live. After 1 months later bound solution, after the new shoots grow, should be promptly cut anvil and removal of rootstock suckering, promote the growth of Huang Yehuai. If autumn connected, unbundling, second year spring before germination cutting stock.
The grafted seedlings, the summer after germination, should be promptly except adorable, promote the growth of new shoots. The seedling height 60 centimeters, to cultivate the straight trunk, with bamboo sticks tied or shoot, until the desired height. Rhizosphere Budding Seedlings was high up to 3 cm, DBH 2 cm, 2 to 3 years to the nursery for greening engineering.
