Abstract

A new sterile plant variety has many of the characteristics of the `Lavender Doll` variety and in comparison to this variety has about the same growth rate, tendency to branch when pruned, and specimen size at maturity. It has a greater natural tendency to branch without pruning, a much greater tendency to form more compact specimens with a more upright and erect posture at maturity and the phylloclades are usually shorter in length and narrower in width. The new variety has a greater resistance to nutrient deficiencies and known problem diseases of the related varieties and it is more resistant to bud abscission and provided with a greater tendency to form multiple buds on the branch tips. It has a habit of producing more blooms with about the same bloom life as that of the `Lavender Doll` variety but at a noticeably earlier date in the blooming season. The blooms of the new variety closely resembles the bloom of the `Lavender Doll` variety in color but at full bloom appears more robust and may be distinguished therefrom by a shorter perianth tube, a sepaloid series of tepals that have a smaller number of tepals which have shorter length dimensions and narrower blade widths, a tube laminating series of tepals with shorter length dimensions and a tube forming series of tepals that have longer length dimensions and slightly greater blade widths.

Description

The invention relates to a new and distinct plant variety of the Cactaceae family and which has been named the Zygocactus truncatus `Lavender Doll II` by the inventor.
Certain plant varieties of the Cactaceae family are well known in the foliage plant market and among these are the varieties of the truncatus species of the Zygocactus genus and which are commonly referred to as "Christmas Cacti" for they tend to bloom in the months of November and December in the Northern Hemisphere and hence appear in the retail market area primarily during the Thanksgiving and Christmas seasons.
Among the various Zygocactus truncatus varieties is the `Lavender Doll` variety. This variety is a fertile variety that has a generally "purplish" colored bloom and its characteristics are set forth in U.S. Plant Pat. No. 3,690.
A general objective of the invention has been to develop a variety of the Cactaceae family which provides a bloom that closely resembles the `Lavender Doll` variety in color but which produces sterile specimens that exhibit a more compact (denser) growth habit and a more upright and erect posture at maturity than the `Lavender Doll` variety. Yet another objective has been to develop a sterile variety of the truncatus species of the Zygocactus genus which provides blooms that closely resemble the `Lavender Doll` variety in color and in bloom life, but which mature at an earlier date than those of the `Lavender Doll` variety so that the demand for such bloom colors in the market place can be met earlier during the marketing season. Still another objective has been to develop a variety with a bloom similar to that of the `Lavender Doll` variety but which is more robust in appearance and has a habit of forming more of such blooms on specimens of comparable size and maturity in comparison to the `Lavender Doll` variety.
The objectives of the invention have been fully realized by the development of the new plant variety hereinafter described in detail. The new plant variety was developed in a nursery located at Winter Garden, Fla. from a seed pod secured by self pollination on a specimen of an unnamed research variety that is a descendant of the `Kris Kringle` variety that is characterized by a "reddish" colored bloom and forms the subject matter of U.S. Plant Pat. No. 3,688. The seeds taken from the fertilized seed pod were cultivated at the mentioned nursery location and after prolonged observation of the seedlings, the plant of the new plant variety was selected and asexually reproduced by the inventor at the Winter Garden nursery by the propagation of stem cuttings taken from the original plant. The unnamed research variety has not appeared in the market area.
Through successive propagations, it has been ascertained that specimens of the new plant variety generally resemble the `Lavender Doll` variety but are distinguishable from specimens of this variety and the parent variety and other related varieties known to the inventor, by a growth habit which is evident in plant specimens propagated and grown under nursery conditions utilized in the growing of tropical plants at Winter Garden, Fla., as combining the following principal characteristics:
1. A growth rate, tendency to branch when pruned and specimen size at comparable stages of maturity that are about the same as those of the `Lavender Doll` variety.
2. A greater natural tendency to branch without pruning and a much greater tendency to form more compact specimens with a more upright and erect posture at maturity than the `Lavender Doll` variety, the phylloclades on such specimens being usually shorter in lengths and narrower in widths than those of the `Lavender Doll` variety.
3. More resistance to bud abscission and a slightly greater tendency to form multiple buds on the branch tips than exhibited by the `Lavender Doll` variety.
4. A slightly greater resistance to nutrient deficiencies and known problem diseases of the related variety in comparison to the `Lavender Doll` variety.
5. A habit of producing more blooms with about the same bloom life (6-8 days) and at a noticeably earlier date (7-10 days) in the blooming season on specimens of comparable maturity and size when compared with the `Lavender Doll` variety.
6. A bloom which in color closely resembles the bloom of the `Lavender Doll` variety, but which at full bloom appears more robust and may be distinguished therefrom by
a. a sepaloid series of tepals that have a smaller number of tepals, and tepals with shorter length dimensions and narrower blade widths,
b. a tube laminating series of tepals that have tepals with shorter length dimensions,
c. a tube forming series of tepals that have tepals with longer length dimensions and slightly greater blade widths, and
d. a perianth tube which is conspicuously shorter in length.
7. Specimens that are sterile.
The accompanying drawings serve by color photography to illustrate the new plant variety and wherein one sheet photographically illustrates a 12 month old plant specimen that was propagated in March and pruned to two tiers above the propagated stem cutting in July of the year of propagation. Yet another sheet photographically illustrates a pair of phylloclades and attached blooms, one being seen in the process of opening and the second at full bloom. The third and fourth sheets photographically illustrate the bloom, with one sheet illustrating the bloom as generally seen along the axis of the perianth tube and the other illustrating the bloom more or less from the side and at an acute angle to the axis of the perianth tube.
The following is a detailed description of the new plant variety with colors and hues, unless otherwise clearly indicated by the text through the absence of color notations being named in accord with the ISCC-NBS Method of Designating Colors, (U.S. Dept. of Commerce, National Bureau of Standards, Circular 553, issued Nov. 1, 1955) the named colors being interpreted from color notations derived by comparison with the color specimens in the "Neighboring Hues Edition" of the Munsell Book of Color, published by the Munsell Color Company, Inc. of Baltimore, Md. The description is further based on observations of well fertilized plants of less than two years of age from initial propagation and which were grown under 50-75% shaded glasshouse nursery conditions in the Winter Garden, Fla. area and wherein temperatures range from about 60° F. to about 85° F. during the winter months, from about 75° F. to about 95° F. during the summer months, and are otherwise ambient during the intervening periods.
I. Name: Zygocactus truncatus `Lavender Doll II`.
II. Parentage: A self pollinated product of ZH9636-T, an unnamed research variety which in comparison to the new plant variety is a less compact, slightly slower growing variety with less frequent branching and a less erect posture. The parent has a slightly larger bloom with slightly wider tepals which may be considered as generally "reddish" in color. Its perianth tube is also longer than the new variety.

VIII: Growth Habit: The new plant variety has about the same rate of growth, tendency for branching when pruned, and size at comparable stages of growth, as compared to the `Lavender Doll` variety. However, it forms more compact (denser) specimens and exhibits more frequent branching without the need for pruning than the `Lavender Doll` variety. It also has a more erect posture by comparison at maturity.
The new plant variety, as compared to the `Lavender Doll` variety has a slightly greater resistance to nutrient deficiencies and a slightly greater resistance to known problem diseases of the related varieties such as Pythium and damp-off fungii.
The blooms produced by the new variety on specimens of comparable age as compared to those of the `Lavender Doll` variety are more resistant to bud abscission. There is a greater tendency to form multiple buds on the branch tips and the blooms of the new variety have about the same bloom life (6-8 days) as those of the `Lavender Doll` variety but they appear in the blooming season at a noticeably earlier date (7-10 days) than those of the `Lavender Doll` variety.
The bloom of the new plant variety closely resembles the bloom of the `Lavender Doll` variety in color. However, the bloom of the new variety has a more robust appearance and may be distinguished from that of the `Lavender Doll` variety by
a. a sepaloid series of tepals that have a smaller number of tepals, and tepals with shorter length dimensions and narrower blade widths,
b. a tube laminating series of tepals that have tepals with shorter length dimensions,
c. a tube forming series of tepals that have tepals with longer length dimensions and slightly greater blade widths, and
d. A perianth tube which is conspicuously shorter in length.
In addition to the above, specimens of the new plant variety are sterile.
The following is a general description of a specimen of the new plant variety which was grown from the propagation of a single phylloclade in a nursery at Winter Garden, Fla.
Age of plant: 20 months from initial propagation of single phylloclade and pruned twice, once in the 6th month to the second tier above the propagated phylloclade and again in the 17th month to the third tier above the propagated phylloclade.
