<p style="text-align: justify;"><span style="font-size: medium;"><strong>Aim: </strong>To determine which of the grapevine organ is the richest in stilbene, like the t-piceid, t-resveratrol and ε-viniferin and would it be useful as by-product of viticulture for processing stilbene concentrate.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><strong>Methods and results: </strong>Nine organs, such as cane, buds, shoot tips, inflorescences, clusters at veraison, matured berry skins, seeds and cluster stems, of Merlot grafted on Teleki Kober 5BB rootstock were collected during a year and its ethanolic extractions were analyzed via HPLC-FLD. Stilbene content of the different organs occurred in a wide range, the lowest was 3.15 mg/kg dry weight (dw) measured in the seeds and the highest 2265 mg/kg dw in the buds.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><strong>Conclusion:</strong> The present research demonstrated that different grapevine organs contain different amount of stilbene in the vineyard. The winter-buds, the roots and the matured cane internodes of Merlot are significantly richer in t-resveratrol and t-ε-viniferin than the green vegetative and generative parts we examined in one growing year. </span></p><p style="text-align: justify;"><span style="font-size: medium;"><strong>Significance and impact of the study: </strong>According to our knowledge there was no stilbenes measuring in several plant organs of a vine cultivar in field study, in vineyard. Our research pointed out the pruned cane could be primary source of stilbene of the health-industry. Beside that grape root is a by-product of grapevine nursery is also rich in stilbene. </span></p>

The variation in the relative amounts of the terpenes of the mature and young leaves, buds, and twigs of blue spruce was investigated during a full year. As with the spruces that were investigated previously, large changes were recorded only in the buds and in the young leaves after bud burst. The variations that were recorded in the latter for santene, tricyclene, camphene, camphor, bornyl acetate, and limonene were similar to those that were found in white spruce, but those of car-β-ene, α-pinene, and β-pinene differed. Several quantitative differences in the oil of the winter buds were also recorded. The variation of β-pinene correlated negatively with that of sabinene, γ-terpinene, and terpinolene. A transient diterpene alcohol of the geranylgeraniol type was found in the buds and young twigs during spring. The seasonal variation of the terpenes of the twig oil was smaller than the twig-to-twig variation within a tree. The implications for chemosystematic studies are discussed.

Geographical Locations

Clonal woody crop germplasm collections often originate and are grown in distinct geographical locations. Because the degree of cold-hardiness is known to be a factor in the successful use of dormant bud cryopreservation for Malus, it was suggested that material from relatively warmer climates would not respond to cryopreservation as well as material from colder environments. To test this hypothesis, the effect of growing provenance on cryosurvival of dormant buds from three Malus (apple) cultivars grown in three locations (Geneva, NY; Davis, CA; and Corvallis, OR) was tested in 3 consecutive years. Dormant winter buds were harvested at the three locations, cryopreserved, and bud viability was tested by grafting. The collective 3-year mean viability for cryopreserved dormant apple buds for the three locations ranged from 63% to 81% of the buds surviving with the highest survival from the Corvallis site; however, the Geneva twigs were exposed to the lowest preharvest temperature. These results suggest that the temperature at the growing location may not hinder application of the dormant bud cryopreservation method with Malus to the extent previously speculated.

Nine seed lots of Pinus banksiana Lamb. and one of P. contorta var. latifolia Engelm. were grown for 115 days on five nitrogen levels and two photoperiods. The nitrogen levels were: zero N—no nitrogen, [Formula: see text], [Formula: see text], 1N—203 p.p.m., and 2N—406 p.p.m. The two photoperiods were a long-night photoperiod (10-hour day) and a broken-night photoperiod (9.5-hour day followed by 0.5-hour light break in the middle of the dark period). The plants, five per vessel, were analyzed for their response to treatments in terms of growth, development, and nitrogen content.(1) The breaking of the night doubled the height, total dry weight, and leaf weight and increased root weight and nitrogen absorption, but it lowered the number of fresh, active root tips, the proportion of the plant in root tissue, and the nitrogen concentration, inhibited production of secondary leaves, and delayed winter bud formation.(2) The increase in nitrogen level in the medium lowered the percentage of fresh, active root tips, the proportion of the plant in root tissue, and the production of winter buds; it increased the content and concentration of nitrogen in the plants. Up to a certain maximum (about [Formula: see text]), it increased the dry weight and height of the plants.(3) The interrelation of growth and developmental stimuli is discussed. It is suggested that growth is an important factor in controlling development.
