Opis:
Relationship between the degree of cutting lignification and rooting ability was studied. Anatomical changes in cuttings were observed, too. The study involved azalea hybrids from groups: Gent, Rustica Flore Pleno, Occidentale and Knap Hill, which can be propagated vegetatively by shoot cuttings. The cuttings were apical parts of shoots, 7-10 cm long. They were collected at various stages of lignification. Rooting was performed in a greenhouse with controlled temperature of the rooting bed. Only the penetrating observation of mother plants allows to determine the best period of taking the cuttings. The cuttings were treated with a growth regulator, 0.5% IBA (indolebutyric acid), combined with Captan in talcum powder. Sand and peat (1:2) were used as a medium for rooting.

Opis:
Flowering and fruit setting was analyzed in specimens of Chamedaphne calyculata (L.) Moench growing in a natural stand in the “Sicienko” reserve in the Drawa National Park. Seed production, seed viability and shoot rooting was investigated. It was shown that Chamaedaphne calyculata has abundant flowers but sets few fruits. Numerous seeds (even up to 87) were found in fruits; however, the percentage of developed seeds was low and ranged from 17% to 45%. The viability of developed seeds was similarly low (maximum 29%). The performed germination test showed a positive effect of stratification on the breaking of seed dormancy. Obtaining seedlings from seeds sown in vitro on agar medium was a considerable success. Shoots cut perpendicularly to the shoot axis, with a 1-cm incision on the side and treated with a rooting agent, rooted 100%. Shoots which were not treated with a rooting agent, irrespective of their having been incised or not, rooted 78%.

Opis:
Popularisation of historical rose cultivars is important for overall increase of biodiversity within currently available assortment, however their vegetative propagation is rather difficult. Possible scenario behind it is that commonly used one-bud leafy cuttings have limited storage capacity due to the small size of the stem. We hypothesised that the treatment of cuttings this rose with rooting preparations would positively affect on the condition of their leaves. We tested the effect of preparations based on seaweed extracts (Bio Rhizotonic, Root Juice, Bio Roots) as well as commonly used root stimulants (Ukorzeniacz Aaqua and Ukorzeniacz Baqua containing 0,4% IBA or 0,2% NAA respectively) on the viability potential of the Rosa ‘Duchesse d’Angoulême’ cuttings. We have monitored the senescence process in leaves by the total soluble protein, chlorophyll and carotenoid content measurements. In order to test the potential effect of the mother plant and timing of shoots acquirement cuttings for the experiment were taken from mother plants at four different maturity stages (flower buds closed; all flowers open; just after petal fall and 7–14 days after petal fall). As expected the amount of the measured components in mother plants varied in individual phases of shoot maturity. This feature influenced the positive effect of rooting stimulants on cuttings viability. The most striking effects were in rooted cuttings derived from shoots collected just after flower petal fall. Observed increase in soluble protein and chlorophyll content did not correlate however with the percentage of obtained rooted cuttings. Based on that we can speculate that the biological basis of observed positive effect of natural rooting preparations on the ‘Duchesse d’Angoulême’ rose is complex and does not rely on the delay or inhibition of senescence process.

Opis:
Observations of Japanese pagoda trees indicate that they undergo a full cycle of vegetative and generative development without self-renovation. The aim of this study was to obtain a successive media protocol propagation of Japanese pagoda tree by in vitro cultures. The effects of growth regulators were studied with reference to primary regeneration, shoot multiplication and rooting. As explants source were used the part of shoot of 90-year-oldtree. Explants were placed on MS (Murashige and Skoog 1962) basal medium with the addition of 6-benzylaminopurine – BAP (1.0–2.0 mg dm-3), thidiazuron – TDZ (0.1–0.3 mg dm-3) and indole-3-acetic acid – IAA (0.5–1.0 mg dm-3). BAP was the growth regulator which significantly increased shoot regeneration on initial explants. TDZ in turn, inhibited the formation of adventitious shoots and caused the explants which had been placed on the medium to die. The multiplication of the Japanese pagoda tree by in vitro cultures should be conducted on MS media with the addition of 0.5 mg dm-3 BAP, and they should be rooted on media with the addition of 0.3 mg dm-3 indole-3-butyric acid – IBA. It seems, that devising an efficient method of Japanese pagoda tree micropropagation is realistic.
