The difference between Rosa chinensis & Rosa rugosa
Rosa rugosa & Rosa chinensis is the same family with the same genus of different species of sister flowers, the common point is: both rosa family rosa genus plants; Deciduous or semideciduous shrubs, stems erect or climbing, often spiny;Leaves alternate, odd pinnate, compound, with stipules;Flowers solitary or corymbose;Sepals and single petals each five, double petals most;Stamen majority, pistil majority is enveloped inside ampulla shape receptacle, receptacle maturation changes fleshy, contain most or a few bony achene.The likeness on exterior configuration, make a lot of people mix up rose and the rose that contain fragrance together, actually both have very big distinction.
1.the difference between the flowers:
Color: Rosa rugosa are purple, pink and white, etc.
The Rosa chinensis has many colors;Have white, red, pink, violet, yellow and green wait for color, all kinds have the cent of depth, some still have stripe and dot or compound color, it may be said that multicolored.
Bouquet: single, double and semidouble, but variable in size and shape.The Rosa rugosa after full bloom assumes flat dish shape, flower diameter is commonly 6-8 centimeters, maximal 10 cm, flower is solitary or a few gather in leaf axils, flower is short peduncle, have thorn, receptacle is smooth. Rosa chinensis has various shape, floret diameter has 2-3cm, big flower diameter has 10-20 cm;There are various types of petals, including apical valve, reverse roll valve, kale leaf-like valve, etc.Flowers are usually terminal, with several clusters, a few loosely integrated corymbs, long stalks, and nearly spineless.
Style:Rosa rugosa style joined with a synthetic head, inserted at the mouth of the receptacle;Style detached from receptacle, very long.
Calyx: calyx is 5 pieces.The calyx of Rosa rugosa is mostly valvular, when the flower opens, calyx and flower develop at the same time;When the Rosa chinensis is not yet open, the sepals open first, and when the flower is open, the sepals are reversed, usually pinnate.
Life span of flower: the life span of a single rose is generally 1 day, 2 days at most, usually in the morning when it opens, in the evening when it Withers;The life span of Rosa chinensis is short 3-5 days, as long as 7-10 days.
The difference of leaves:Rosa rugosa consists of 7-9 lobules composed of pinnate compound leaves, lobules elliptic or obovate in long elliptic shape, apex acute or obtuse, margin obtuse serrate, leaves 2-5 cm long, surface green, glabrous, lustrous, veins sunken and wrinkled, back slightly white powder and pilose;Petiole tomentose and prickly, stipules half as long as leaf blade.The leaves of the Rosa chinensis are composed of 3-5 lobules with pinnate compound leaves, lobules broadly ovate or ovate-oblong, apex pointed, margin serrated, 2.5-6 cm long, glabrous on both sides, surface green, flat, smooth, without wrinkling, shiny, petiole spiny or spineless;Stipules one-third the length of petiole.
Stem difference: Rosa rugosa rose stem erect tufted, young stem green, the next year to become brown red, old stem grayish brown with gray powder, stem base with thick prickles and thin and dense spines;More than three years old stems at the base of the thick prickles off, the stems are thick prickles;Branches robust, ca. 2 m tall, densely spiced and bristly, branchlets densely villous.Rosa chinensis stems erect, some species of longer branches like vines.Young stem green, slightly reddish, some purplish red, with or without thorns, are hairless, prickly hooks, scattered and few, old branches grayish brown, peel off.
Fruit difference: Rosa rugosa fruit oblate, green, ripe orange red;The fruits of the Rosa chinensis are round and spherical, large, green, and orange when ripe.
The difference of roots: the main roots of rose and Rosa chinensis do not develop, the branch roots and fibrous roots are developed, the cross root of rose can root tillers, to reproduce new plants, Rosa chinensis does not occur in the root tillers.
Watching the leaves.Leaves of rose, odd-pinnate, 5-9 lobules, prickly.But rose, odd pinnate compound leaves, leaflets 3-5, leaves smooth, flat and spineless;
Rose and rose have their own fragrance, but comparatively speaking, the aroma of rose is much stronger than that of rose.Rose is used commonly extract essence, its aroma nature is full-bodied, make a person get drunk, and the sweet smell of rose season is light.
