* With the cone-shaped center (classical form of the flower Hybrid Tea Roses - Long internal petals folded into a cone.)
* With a loose center (Internal petals not well closed, and form the middle of a vague form.)
* Haywire (originally correct form at the end of a flower blooming - wide open petals, stamens are visible.)
* Spherical (multiple petals form a concave bowl, covering the center of the flower.)
* Cupped (multiple petals form a cup, not covering the center of the flower.)
* Square (Internal petals form a cone, but form four separate sectors.)
* Planar (flat, slightly concave in the middle of a flower with many petals.)
* Rosette (flat, slightly concave in the middle of a flower with numerous short, arranged in regular rows petals.)
* Pomponius (rounded flower with numerous short, arranged in regular rows petals)
Types of leaves
Typical Rose leaf consists of five to seven leaflets smooth, surface that can reflect light in varying degrees. In some varieties of roses leaves glisten as much as if rubbed with oil, the leaves of other varieties almost dull. In addition to these two cases, there are many intermediates. Therefore it is possible to distinguish strongly shiny, glossy and matte smooth leaves.
Not all Rose sheet with five or seven leaflets - some, such as grade Canary Bird, have beautiful feathery leaves with more numerous leaflets. Leaf surface is also not always smooth - have withered rose leaves with deep grooves.
Leaf color
Almost all adult leaves are green roses, from the dull light green in class Fred Loads to dark green - the variety Felicia. The figure below shows three main different types of leaves in color - light green, green and dark green.
In some varieties of roses bronzoveyuschaya foliage, with a distinctive copper hue. From this rule there are exceptions. In shrub roses young leaves are often purple or scarlet in hue, with some roses, for example, rose krasnolistnoy (Rosa rubrifolia) and a variety Buff Beauty, red color and retain adult leaves. On the other hand, the hybrid roses with white leaves are bluish-green. In some RoseAs, for example, rose wrinkled, extremely beautiful autumn leaves.
That is, shortened modified stem that carries the function of sexual reproduction.
Wild species of grapes - dioecious plants: in some plants have buds only male flowers, on the other - functional female. Plants with male flowers have a rudimentary type of pestle, and therefore do not form fruits (Fig. 1).
The majority of cultural grapes flowers are bisexual. But along with them, there are varieties with functionally female flower type (Madeleine Anzhevin, Nimrang, Katta-Kurgan, Chaush white, etc.).Hermaphrodite flower has a normally developed pistil consisting of ovary, column, stigmas and stamens, which are much longer than the pistil (Fig. 1a).
Functionally, female flowers have well-developed pistil, filaments shorter than the pistil, and bent down, the pollen is underdeveloped and incapable of fertilization (Fig. 1 b). Therefore, cultivars with functionally female, the type of flower in need of cross-pollination.
What is the nectary glands,
In the flowers of all types of grapes at the base of the ovary, there are small glands, nectaries green, yellow and orange. They secrete essential oils, So the flowers have a strong pleasant scent of mignonette.
Pollen is a very fine grapes and easily transported by wind
During flowering, after the flower opens (abscission cap) on the stigma of the pistil stand droplets, which adhere pollen. Pollen germinates in the dust tubes penetrating the ovary, where fertilization occurs. Pollen germinates better at temperatures of 30 ° C.
After fertilization, the ovary begins to grow vigorously. However, not all the buds develop in the ovary BerriesSome of them crumbles. Abscission 40-60% of the ovaries is normal. Significant sloughing, uncharacteristic of the class, observed in adverse weather (rain, wind, low temperatures), with little food or inflorescences in the absence of pollen.
