Patents
Search within the title, abstract, claims, or full patent document: You can restrict your search to a specific field using field names.
Use TI= to search in the title, AB= for the abstract, CL= for the claims, or TAC= for all three. For example, TI=(safety belt).
Search by Cooperative Patent Classifications (CPCs): These are commonly used to represent ideas in place of keywords, and can also be entered in a search term box. If you're searching forseat belts, you could also search for B60R22/00 to retrieve documents that mention safety belts or body harnesses. CPC=B60R22 will match documents with exactly this CPC, CPC=B60R22/low matches documents with this CPC or a child classification of this CPC.
Learn MoreKeywords and boolean syntax (USPTO or EPO format): seat belt searches these two words, or their plurals and close synonyms. "seat belt" searches this exact phrase, in order. -seat -belt searches for documents not containing either word.
For searches using boolean logic, the default operator is AND with left associativity. Note: this means safety OR seat belt is searched as (safety OR seat) AND belt. Each word automatically includes plurals and close synonyms. Adjacent words that are implicitly ANDed together, such as (safety belt), are treated as a phrase when generating synonyms.
Learn MoreChemistry searches match terms (trade names, IUPAC names, etc. extracted from the entire document, and processed from .MOL files.)
Substructure (use SSS=) and similarity (use ~) searches are limited to one per search at the top-level AND condition. Exact searches can be used multiple times throughout the search query.
Searching by SMILES or InChi key requires no special syntax. To search by SMARTS, use SMARTS=.

Description
translated from
- Size:
-
- Generally.—Considered medium large as compared to other common commercial nectarine cultivars. The tree size the first year was approximately 280 cm. The tree was pruned during each following dormant season to a height of approximately 250 cm. Current seasons shoots growth could reach 80 cm. So the tree size from the second year (second and next years) reached a final height of 330 cm with current seasons shots length comprised.
-
- Spread: Approximately 1.0 meter. The whole orchard was oriented to a central leader organisation, with tree lines spaced of 4.0 meters and trees spaced of 1 meter in a same tree line.
- Vigor: Considered vigorous. The present variety grew from about 200 cm to 280 cm in height during the first growing season. For second and following seasons, the variety was pruned to an approximate height of 250 cm.
- Productivity: Very Productive. Fruit set is spaced by thinning to develop the remaining fruit into the desired market sized fruit. The number of the fruit set varies with the prevailing climatic conditions and cultural practices employed during the bloom period, and is therefore not distinctive of the present variety.
- Bearer: Very regular. A thinning of 1 fruits on 3 was necessary for the tree valorisation. Thinning may not be too important because of the high magnifying potential of the fruit. Thinning was necessary every year during the past 4 years.
- Form: The ‘Nectariane’ variety has naturally a semi-upright standing.
- Density: Considered medium dense and dense.
- Hardiness: The present tree was grown and evaluated in France. The variety appears to be hardy under typical central Pyréeées-Orientales departement climatic conditions. Experimentations on different sites with winter chilling requirement comprised between 350 hours and 1200 hours showed a good behaviour of the tree in all cases. No damages were caused by ascertained temperatures as low as −12 degrees Celsius. The tree was also very resistant to frosty springtime weather.
- Diameter: Approximately between 8.0 cm and 9.5 cm in diameter when measured at a distance of approximately 30 cm above the soil level, on trees from the second growing season. The branching begins at 50 cm above the soil level.
- Bark texture: Considered moderately rough.
- Lenticels: Numerous lenticels are present on trees from the second growing season. The lenticels range in size from approximately 3.0 millimeters to 7.0 millimeters in width, and from 1.5 millimeters to 2.8 millimeters in height.
- Lenticel color: The outside of lenticels has a silver-grey color (RHS Grey 201 D to RHS Black 202 D), whereas the inside is considered brown (RHS Greyed Orange 166B).
- Bark coloration: The bark has a silver-grey color a little more pronounced than lenticels outside color (RHS Grey 201 C to RHS Black 202 C).
- Size: Mature branches are considered medium to thick for the variety, and current season shoots are considered medium for the variety.
- Diameter: Average as compared to other nectarine varieties. The current season shoots have a diameter from 5.0 to 7.0 millimeters, and branches of trees from the second growing season have a diameter comprised between 25.0 and 35.0 millimeters.
- Surface texture: Average, wood which is several years old has no furrowed appearance.
- Crotch angles: Primary branches are considered variable, but the crotch angles are generally between 60 degrees and 70 degrees from the horizontal axis. This particular characteristic is not considered distinctive of the variety, however.
- Current season shoots:
-
- Surface texture.—Substantially glabrous.
-
- Internode length: Generally 25 millimeters to 30 millimeters.
- Color of mature branches: Medium brown (RHS Grey Brown 199 A).
- Current seasons shoots:
-
- Color.—The color of new shoot tips is considered a light yellow green (RHS Yellow Green 144 A-B) on lower part of new shoot tips, whereas the upper part is colored in brown-orange (RHS Greyed Orange 173 B-C-D).

-
- Flower buds:
-
- Generally.—At pre-floral stage of development, the floral buds are conic in form with a round tip. Their form is evolving until blooming, with variables dimensions. Just before blooming, floral buds are approximately 10.0 millimeters wide and approximately 18.0 millimeters long.
-
- Flower buds:
-
- Color.—This characteristic is dependent upon the proximity to bloom. At pre-floral stage of development, the bottom of the flowers buds, formed by sepals, is of purple-brown color (RHS Greyed Purple 183 A); the corolla, formed by petals, is generally of purple pink color (RHS Red Purple 60 D). Petals color shows an evolution until the end of flowering. The buds are considered hardy under typical central Pyrénées Orientales departement climatic conditions.
-
- Hardiness: No winter injury was noted during the last several years of evaluation in the central Pyrénées Orientales departement, with winter temperatures as low as −12° C. in December or January. The current variety has not been intentionally subjected to drought or heat stress, but the variety showed a very good resistance in orchard to temperatures up to 42° C. with an average temperature between 28° C. and 30° C. during 3 weeks in summer.

-
- Use: The subject variety ‘Nectariane’ is considered to be a nectarine tree of the very early season of maturity, and which produces fruits that are considered firm, attractively colored. Fruits are excellent for uncooked consumption, crunchy or at full maturity. Due to their flesh quality, firmness and density, they can also be commercialized as 4th range product (packed fruit or fruit in bags for example). And they are also useful for both local and very long distance shipping.
- Keeping quality: Excellent. Fruit stayed a little more than one week on tree before harvest and then, has stored well more than 4 weeks after harvest at 2.0 degree Celsius. They have a slow maturation and a long shelf life both on the tree after growth completion and after harvesting without alteration.
- Shipping quality: Considered very good. The fruit of the new nectarine variety showed minimal bruising of the flesh or skin damage after being subjected to normal harvesting and packing procedures. Its resistance to handling during harvest and packing and its long shelf life without alteration after harvest easily permit 3 weeks-shipping at 2 degrees Celsius.
- Resistance to insects and disease: No particular susceptibilities were noted. The present variety is not very sensitive to powdery mildew, or conservation diseases and decay due to its thick and strong skin.
