Abstract

Poinsettia `842` is a new cultivar, distinguished by bright red, upright flower bracts, dark green dentate foliage, prolific branching and a 9 week flowering response time. The new plant produces a very desirable branched flowering pot plant for the late-season holiday market. Poinsettia `842` is resistant to epinasty after being confined to shipping containers. The post-production foliage and bract retention is excellent even under low light intensities in the consumer's home.

Description

BACKGROUND OF THE PLANT
This new Poinsettia cultivar, `842`, originated as an induced self-branching sport of a seedling known as "P-72" (not patented) in my greenhouse in Encinitas, Calif. It was selected because of its upright, bright red flower bracts, dark green dentate foliage, prolific branching and late-season flowering response; traits that distinguish it from other poinsettia cultivars, and seem to make it a desirable plant for commercial greenhouse production. After selection, `842` was vegetatively reproduced from stem cuttings for test purposes in Encinitas, Calif. "P-72" is a proprietary plant and there are no specimens in the public domain. Poinsetta "P-72" is not self-branching in that no axillary branches develop as long as the apical bud is not removed (pinched). `842` is self-branching in that during development axillary branches elongate without removal of the apical bud. If under short day conditions, the axillary branches will develop inforescences. By subjecting clones of this plant to successive generations of vegetative propagation, it was demonstrated that the distinctive characteristics of `842` held true from generation to generation.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
Poinsettia `842` is illustrated in the accompanying color photographs.
The upper photograph is a side view of a branched plant.
The lower photograph is a top view of the same `842` plant showing flower and bract formation.
DESCRIPTION OF THE PLANT
The following is a detailed description of this new Poinsettia as observed in Encinitas, CA, USA during December 1996. Observations were recorded from flowering plants, grown as one branched plant per pot. The pot was 14 cm in diameter and 11 cm in height. Color designations are compared to the 1986 edition of R.H.S. Colour Chart, first published in 1966 by The Royal Horticultural Society, London, England.
THE PLANT
Origin: Sport of a seedling. The sport was induced by application of the procedures set forth in U.S. Pat. No. 4,724,276 to the seedling parent plant. Rootstock used was `603` (U.S. Plant Pat. No. 9,952).
Classification:
Botanical.--Euphorbia pulcherrima Willd.
Common name.--Poinsettia.
Cultivar name.--`842`.
Form: Shrub.
Height: Short--medium.
Growth habit: As a single stemmed plant, upright and vigorous with self-branching side shoots. The application of a chemical growth retardant may be needed to restrict height for commercial pot plant production. I observed a branching plant in a pot with an overall height of 38 cm and an overall width of 54 cm. The diameter of individual inflorescences is 26 cm.
Branching: Axiliary branches will develop and terminate in an inflorescence without pinching. However, it is usually desirable to pinch `842` before flower induction and remove all terminal dominance. Then, all axillary branches will develop uniformly and at a faster rate.
Growth rate: Rooting of stem cutting occurs in 12-18 days under intermittent mist. The plant will flower in about 9 weeks under continuous long night conditions and night temperatures of about 16-18° C.
Foliage: The foliage is clean and uniformly dark green from bottom to top of the plant. The leaves are of medium size, leaf blades typically 14 cm long and 11 cm wide with green petioles 5 cm long. The upper leaf surface is glabrous and smooth and the under surface is finely pubescent.
Leaf shape.--Typical leaves are generally ovate with obtuse to acute bases and acuminate tips. Leaf margins are dentate with mostly 2 lobes on each side of the leaf blade.
Color.--Upper side -- Dark green, near R.H.S. 147A. Under side -- Green, near R.H.S. 147B.
Retention.--The foliage lasts extremely well even under low light intensities in the consumers home.
Bracts: Generally there are about 12 upright, bright red bracts of various sizes subtending the cyathia. The primary bracts have blades typically 14 cm long and 8-9 cm wide with petioles 3 cm long, reddish on top and greenish on the under side. Bract surface is somewhat rugose.
Shape.--Primary bracts are ovate with acute bases and acuminate tips. Primary bract margins are dentate with one or two lobes on either side of the bract. Secondary bracts are of various sizes, broadly elliptical, and have entire margins.
Color.--Upper side -- Bright red, near R.H.S. 45B. Under side -- Red, near R.H.S. 45C.
Flowers: Generally, 9-12 cyathia (flowers) per inflorescence are present when the plant is in full bloom. Each cyanthium is about 6 mm long and 5 mm wide, green in color, and fringed bright red at the distal end. One yellow nectar cup, tinged red, protrudes from the side of each cyathium. The flower pedicel is also green and about 3 mm in length. The stamens protruding from the cyathia are dark red. The anthers are bifurcate; the pollen is yellow and copious. The stigmas are dark red and trifurcate.
Nectar exudate.--None.
Seeds.--Self-incompatible. Fertility.--Not observed.
Post production: Poinsettia `842` is resistant to epinasty after being confined to shipping containers and retains its leaves and flower bracts for several weeks in the consumer's home environment.
Disease resistance: Typical of the species.
