Abstract

A new and distinct Spathiphyllum cultivar named ‘S39’ is disclosed, characterized by dark green, glossy foliage, early foliage production and rapid, compact growth. The new variety maintains its dark green foliage color under higher than normal light conditions, or low nutrient levels. The new variety is commercially suitable for six inch pot production. The new variety is a Spathiphyllum, typically produced as an indoor ornamental plant.

Description

Latin name of the genus and species: Spathiphyllum hybrid.
Variety denomination: ‘S39’.
BACKGROUND OF THE INVENTION
The new cultivar is a product of a planned breeding program. The objective of the breeding program was to develop new Spathiphyllum varieties suitable for 6 inch commercial pot production, and with fast growth, and dark green foliage. The new variety originated from a cross pollination of a proprietary, unpatented seed parent referred to as ‘03-3-1’ and the pollen parent, ‘Power Petite’ U.S. Plant Pat. No. 15,649. The crossing was made during April 2005.
The new variety was discovered by the inventor, Marian Osiecki, a citizen of the US, in September 2006 in a group of seedlings resulting from the crossing. The new cultivar was found in a commercial greenhouse in Altha, Fla.
Asexual reproduction of the new cultivar ‘S39’ was first performed at a commercial laboratory in Altha, Fla. by tissue culture in April of 2007. Subsequent propagation by tissue culture has shown that the unique features of this cultivar are stable and reproduced true to type.
SUMMARY OF THE INVENTION
The cultivar ‘S39’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘S39.’ These characteristics in combination distinguish ‘S39’ as a new and distinct Spathiphyllum cultivar:
    • 1. Very dark green, broad foliage.
    • 2. Early production of secondary foliage, resulting in a full plant growth earlier.
    • 3. Rapidly growing and compact growth habit.
    • 4. Maintains very dark green color under higher than normal light conditions, or low nutrient levels.
    • 5. Spathe production in response to Gibberellic Acid treatment after 10 weeks.
    • 6. Plant habit suitable for 6 inch commercial pots.
PARENT COMPARISON
Plants of the new cultivar ‘S39’ are similar to the seed parent in most horticultural characteristics. The new variety, however, produces shorter, more compact plants. Additionally, ‘S39’ produces shorter, narrower leaf blades and shorter petioles than the seed parent. Spathes of ‘S39’ are smaller and closer to the foliage than the spathes of the seed parent. ‘S39’ has also shown better resistance to the diseases Myrothecium and leaf Phytophthora than the seed parent.
Plants of the new cultivar ‘S39’ are similar to the pollen parent ‘Power Petite’ U.S. Plant Pat. No. 15,649 in most horticultural characteristics. Plants of the new variety however are more vigorous and faster growing than ‘Power Petite’. Additionally, ‘S39’ produces more leaves and produces additional foliage earlier than ‘Power Petite’. Plants of ‘S39’ are taller than plants of ‘Power Petite’. Foliage of the two varieties differs, ‘S39’ produces darker, more upright foliage with less undulation on the leaf blade than ‘Power Petite’. Additionally, plants of ‘S39’ produce spathes earlier and more abundantly than ‘Power Petite’. Plants of ‘S39’ respond after 10 weeks to the normal GA treatment given to commercial Spathiphyllum plants, whereas ‘Power Petite’ responds after 14 weeks.
COMMERCIAL COMPARISON
‘S39’ can be compared to compared to the commercial variety Spathiphyllum ‘S9’ U.S. Plant Pat. No. 9,901 Plants of ‘S9’ are similar to plants of ‘S39’ in most horticultural characteristics, however, plants of ‘S39’ are larger and faster growing than ‘S9’. ‘S39’ has much darker, glossier leaves than ‘S9.’ Additionally ‘S39’ produces more shoots and has a less undulating leaf margin than ‘S9’. Spathes on plants of ‘S39’ are closer to the foliage than the spathes produced on plants of ‘S9’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘S39’ grown in a greenhouse in Altha, Fla.
This plant is approximately 9 months old, shown in a 6 inch pot. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
 DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart 2001, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘S39’ plants grown in a climate controlled greenhouse in Altha, Fla., USA. Temperatures ranged from 20° C. to 25° C. at night to 25° C. to 32° C. during the day. No artificial light, photoperiodic treatments were given to the plants. Plants were treated with Giberellic Acid at 200 ppm, to induce spathe production in approximately 10 weeks. Plants were grown in 80% shade, resulting in approximately 800 to 1200 foot candles of light. Measurements and numerical values represent averages of typical plant types.
