‘Mondo Bay’ Aglaonema

in HortScience

The genus Aglaonema (family Araceae), commonly referred to as Chinese evergreens, have been important ornamental tropical foliage plants since the 1930s (Smith and Scarborough, 1981). Aglaonema are a reliable crop for commercial growers and plants readily adapt to low light and low relative humidity levels encountered under interiorscape conditions. The first commercial Aglaonema cultivars were plants collected from their native tropical habitats, propagated, and sold as ornamentals. Foliage plant breeding studies developed protocols to control Aglaonema flowering (Henny, 1983) and new pollination techniques made seed production routine (Henny, 1985). These breeding innovations have led to the production of many new hybrid cultivars in the past 20 years by both public and private breeders worldwide. Five such Aglaonema cultivars were released previously (Henny and Chen, 2001; Henny et al., 1992, 2003, 2008) by the Foliage Plant Breeding Program at the Mid-Florida Research and Education Center (MREC) in Apopka, FL. These cultivars currently are very successful commercial foliage plants and have become known as the “Bay” series. ‘Mondo Bay’ is the sixth named cultivar to be part of this series (Fig. 1).

Origin

Aglaonema ‘Mondo Bay’ is a selection (hybrid #742-3) from an interspecific cross of A. commutatum Schott ‘Treubii’ with A. nitidum Curtisii. ‘Mondo Bay’ was selected from a hybrid population of 87 plants because of its vigor, excellent basal shoot production, small, narrow leaves, attractive foliar variegation pattern, and arching plant form.

Description

The color descriptions that follow are based on The Royal Horticultural Society's color chart [Royal Horticultural Society (RHS), 1995]. Aglaonema ‘Mondo Bay’ upper leaf surfaces display a dark green background, edge, and midrib (RHS 139A) that are highlighted by lighter gray–green areas (RHS 191A; Fig. 1). These gray–green variegated areas appear in uneven 8- to 10-mm wide bands associated with the lateral veins. The bands originate from the midrib and angle toward the leaf tip to roughly form a V pattern. There are three to four such bands in each leaf separated by the darker green background strips. The leaf underside is a lighter green field (RHS 137C) with the midrib and lateral veins a lighter yellow–green (RHS 148C/D). The leaves are contrasted by petioles that are yellow–green (RHS 148D). Petiole flanges are RHS 148D and contain darker spots of green (RHS 137C). The stem, although hidden from view as a result of the clasping nature of the petioles, exhibits a blend of green (RHS 137C) and lighter yellow–green RHS 148C/D that coalesce in a wavy pattern.

Performance

Growth tests were initiated using 10- to 12-cm long tip cuttings that held three to four leaves each. Cuttings were harvested from Aglaonema ‘Mondo Bay’ stock plants grown in a shaded greenhouse and stuck in 50-celled trays containing Vergro Container Mix A (Verlite Co., Tampa, FL) on 25 Aug. 2006. The cuttings were placed inside a propagation tent (maximum irradiance of 80 μmol·m−2 ·s−1) for 8 weeks. The rooted cuttings were allowed to acclimatize for 2 additional weeks. At this time, one-half of the liners were potted one plant per 1.6-L pot using with Vergro Container Mix A (60% Canadian peat:20% perlite:20% vermiculite) and one-half using Fafard 2 Mix (Conrad Fafard, Agawam, MA; 55% Canadian peat:25% perlite:20% vermiculite) substrate. Plants were grown in randomized block experimental design in a shaded greenhouse, a maximum irradiance of 125 μmol·m−2 ·s−1, under natural photoperiod and a temperature range of 15 to 34 °C. Plants were grown using three fertilizer treatments. The fertilizer treatments were: 1) Osmocote Plus 15N–4P–10K (Scotts-Sierra Horticultural Products Company, Marysville, OH); 2) Nutricote Plus 18N–2.6P–6.6K (Chisso-Asahi Fertilizer Co., Ltd., Tokyo); and 3) Peter's liquid 20N–8.8P–16.6K (Scotts-Sierra Horticultural Products Company). Ten plants per each fertilizer treatment and soil mix (60 plants total) were grown in a completely randomized design for 9 months. Plants treated with Osmocote and Nutricote were retreated every 3 months. The Peter's fertilizer treatment was applied as a 200-mL liquid drench per pot once weekly throughout the duration of the experiment. Data recorded at termination of the study included canopy height, canopy width, length and width of largest leaf, number of basal shoots, and a visual quality rating in which 1 = poor; 2 = fair (not saleable); 3 = acceptable (saleable); 4 = good quality; and 5 = excellent quality. Finished plants were moved into an interior growth room for 3 months with a light level of 25 μmol·m−2·s−1 for 12 h daily at a constant 24 °C. Data were analyzed using analysis of variance procedures of the SAS program (SAS Institute, Cary, NC).

Results

Aglaonema ‘Mondo Bay’ grown in 1.6-L pots reached marketable size in 9 months (Fig. 1). There were no significant differences in growth between soil mixes so the data were combined for analysis. Canopy height and width and number of basal shoots were significantly higher with liquid fertilizer (Table 1). Plants treated with liquid fertilizer averaged 10.7 basal shoots, which was significantly better than the 8.6 and 8.3 for Osmocote and Nutricote treatments, respectively. There were no significant differences in leaf size or overall visual quality resulting from fertilizer effects. Plant quality averaged between good to excellent at all nutritional levels. After an additional 3 months growth under interior conditions, all plants had a visual quality rating of excellent (Fig. 1).
