DETAILED DESCRIPTION OF THE PLANT
Ala was characterized in greenhouse and field conditions. Ala is a unique variety of St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze] discovered under cultivated, mowed turf conditions at the home lawn described above. Ala was identified as higher in density and quality from the surrounding common St. Augustinegrass. Ala was propagated by cutting of stolons, rooting them in soil, and planting of the rooted stolons to provide planting stock for studying performance and for comparisons with commercial varieties. Ala remained stable in both performance and morphological characters after propagation. Ala has been propagated by sod, plugs, and stolons. No seedling establishment from Ala has been noticed in either greenhouse or field plantings, suggesting lack of sexual reproduction.
Ala is distinguished from other varieties of St. Augustinegrass by the combination of characters of white stigmas, yellow anthers, floret number per raceme, raceme length, leaf length, internode length, and lack of leaf hairs. Ala shows a distinct DNA fingerprint. Ala is closest in appearance and performance to Raleigh St. Augustinegrass.
The creeping stolons of Ala are dorsiventrally compressed and root adventitiously at the nodes. Ala lacks rhizomes. Color notations of plant tissues were based on the Munsell Color Charts for Plant Tissues, Munsell Color, Baltimore, Md., 1977. Color notations are affected by light quality and fertility and general growth of the plants. Ala has a distinct lack of purple color in the stolons, in contrast to many St. Augustinegrasses. Leaf blades of Ala are folded in the bud, contracted at the base, and obtuse at the tip. There is an absence of hairs on the leaf blades of Ala. Measured under greenhouse conditions in July 1994, the genetic, adaxial leaf color of Ala is 7.5 GY 5.4, with Raleigh having a color of 5 GY 5/8.
The ligule of Ala is a line of short hairs, approximately 2 mm in length. The leaf sheaths are laterally compressed and are approximately 38.6 mm in length (Table 1), shorter than Raleigh at a mean of 40.9.
The flag leaf width of Ala is 6.4 mm, with Raleigh having a mean of 8.0 mm (Table 2). Ala has white stigmas and yellow anthers, undistinguished in color from other plants of the species (Table 3). The floral region of Ala consists of spikelets partially embedded in a flattened and thickened rachis of a short, unilateral spicate inflorescence with a raceme length of 57 to 71 mm (Table 4). Ala has a mean of 25 florets per raceme, which trends to be a lower number of spikelets than Raleigh, and more than Seville (Table 4). The mean spikelet length of Ala is 3.89 mm, with Raleigh having a mean of 4.23, measured under the same growth conditions. The spikelets of Ala are awnless. The dates of flowering are similar to that of Raleigh.
The mean stolon internode diameter of Ala is 2.38×2.97 mm, less than Raleigh with a stolon diameter of 3.1×3.5 mm. Ala has a mean internode length of 4.8 cm (Table 5), shorter than Raleigh with a mean of 7.8 cm, and longer than Seville with a mean of 4.2 cm. The shorter internode length of Ala compared to Raleigh contributes to a tight turf canopy and high quality. Ala is vigorous in growth, and spreads by leafy stolons with formation of tight turf by tiller production. Ala readily develops adventitious roots, an advantage in vegetative propagation. The rooting depth of Ala appears to be average, without observation of the extremely deep rooting character of some St. Augustinegrasses.
The chromosome number of Ala is 18.
Quality in turf performance may be defined as a combination of characters of color, density, uniformity, and leaf texture. Density is defined as the number of leaves and tillers per unit area. Uniformity is defined as freedom from weeds or diseases. Ala shows high quality turf performance in field trials in Buckholts, Tex., Ala showed quality as a fine leaf texture of 7.0 mm on the second youngest leaf, compared to Raleigh with a leaf texture of 7.2 mm. Ala has good turf performance when mowed at 5 cm mowing height, with a rotary mower. Ala is vigorous in establishing a turf cover, as indicated in the growth from a 7.5% cover to 52.5% in an approximate 6 month period (Table 6). Ala expresses high vigor in tiller density, forming a dense and uniform turf, competitive against weed invasion. Ala is intermediate in rate of greenup, having a mean of 7.5% on Apr. 22, 1994, with Raleigh showing 17.5% and Seville 3.3% on the same date in Buckholts, Tex. Ala was intermediate in entering winter dormancy, earlier than Seville, and similar to Raleigh at Buckholts, Tex.
The high quality performance of Ala may be directly related to the high tiller density which competes with weeds, and the superior winter hardiness (tested as survival in Buckholts, Tex.). Ala has shown good drought resistance with continued growth as unirrigated turf adjacent to Texas Common St. Augustinegrass in Buckholts, Tex. Ala illustrated no excessive thatching tendencies when maintained as turf as observed in Buckholts, Tex., and in the original collection site, Glenwood, Ala. Ala has shown moderate susceptibility to gray leaf spot and brown patch in the Buckholts, Tex. The shade tolerance of Ala has not been tested. The chinch bug and other insect resistances of Ala have not been tested in replicated trials; however, no insect problems were observed in the test areas.
With the presence of white stigmas, yellow anthers, and an absence of leaf hairs, Ala is distinguished from all patented St. Augustinegrasses except #141, 6-72-99 (Delmar), and 6-72-182 (Table 3, 3a). Ala exhibits more florets per raceme than Seville (Table 4), is not different from number of florets per raceme than Raleigh, but has a shorter raceme length than Raleigh. Ala has a flag leaf sheath longer than Seville (Table 1); Seville has a flag leaf sheath longer than 6-72-182 (U.S. Plant Pat. No. 6,922). Ala has a raceme averaging 65.1 mm (Table 4). Delmar has a spike 93 mm in length (U.S. Plant Pat. No. 6,372), with #141 having an average length of 8.97 cm (U.S. Plant Pat. No. 3,834), both longer than Ala. Ala has longer internodes (Table 5) than #141 (U.S. Plant Pat. No. 3,834). In turf evaluations, Ala exhibited a density rating not different from Seville or Raleigh (Tables 6). Ala shows a distinctly different DNA from Seville and Raleigh using PCR DNA fingerprints (FIG. 1).
DETAILED SUMMARY OF DNA FINGERPRINT ANALYSIS
Dr. Lin Wu, Univ. California -- Davis, performed the DNA fingerprint analysis. The St. Augustinegrass DNA fingerprints were Ala, Seville, and Raleigh. The DNA fingerprints were produced by polymerase chain reaction using random primers. The four DNA fingerprint profiles of each variety produced by the primers A9 and A16 from the left to right are the DNA profiles of the two duplicate DNA extractions extracted from the leaf tissue of the vegetatively propagated clones. The results of the DNA fingerprint analysis are summarized:
1. Ala is different from Raleigh by Primer A9 and A16.
2. Ala is different from Seville by Primer A9 and A16.
