Abstract:
The study was conducted during 2011-2013, in the climatic conditions
in the Baltati region, Iasi County. The settings up of the field was done using
direct seeding in the field in protected conditions (solar tunnel) using walnuts
from current year production and have not undergone any treatment to
stimulate germination before sowing. Seeding distance was 75 cm between rows
and 10 cm on the row and sowing depth was 5 cm. For grafting was used chip
budding method, grafting into two periods: August 2012 (the sleeping bud) and
April 2013 (the growing bud). For grafting in August, graft branches were used,
which were shaped in two different moments: removing leaves and stems,
keeping a portion of 2 cm, make two months before harvesting the graft
branches (V1) and trimming the leaves graft branches at harvest (V2). For
grafting in April were used branches harvested in late autumn and stored over
winter in deposits setpoints 2-4 ◦C (V3). The walnut germintion percentage was
61.4%, with grafting procentage of 67.8% (V1), 30.2% (V2) and 48.8% (V3)
and the percentage of grafted trees STAS was 26% at Anica variety and 59% at
Prezident variety.
