Pawpaw (Asimina triloba) is a native North American tree that has potential as a new fruit crop or for use in landscapes, but until recently, little information has been available to nurseries on container-ized production of this species. Pawpaw seedlings develop a strong taproot with a fragile root system, which can be easily damaged upon digging; therefore, most nurseries propagate trees in containers. Pawpaw seed requires stratification for optimal germination and seed is sensitive to desiccation. The seed also cannot tolerate freezing temperatures [ $ <-15\\ ^{○}C\\ (5.0\\ ^{○}F) $]. A well-aerated potting substrate with a high sphagnum peat moss component (>75% by volume), cation exchange capacity, and water holding capacity can be used effectively in container production. Tall containers should be used to accommodate the developing taproot of seedlings. The slow-release fertilizer Osmocote 14-14-14 (14N-6.1P-11.6K) incorporated into Pro-Mix BX potting substrate can be used effectively as the sole fertilizer source at a treatment rate of 2.22 kg·m[p1.4.2] (3.742 lb/yard[p1.4.3]) in containerized pawpaw production. It can also be used at a lower rate of 0.81 kg·m[p1.4.4] (1.365 lb/yard[p1.4.5]) when supplemented with weekly applications of 500 mg·L[p1.4.6] (ppm) of Peters 20-20-20 (20N-8.78P-16.6K) liquid-feed fertilizer. Bottom heating [32 °C (89.6 °F)] of container-grown pawpaw seedlings results in greater lateral and total root dry weight than in seedlings grown at ambient temperature [24 °C (75.2 °F)], which could increase the rate of establishment of seedlings in the field. Bottom heating of container-grown pawpaw seedlings could decrease both the time to produce a saleable plant and the cost of heating greenhouses. Growth of containerized pawpaw seedlings is enhanced by low to moderate shading with polypropylene shade fabric (28% or 51%) outdoors and low shading (33%) in the greenhouse, in a manner typical of that reported for other shade-preferring plants. Low to moderate shading of pawpaw seedlings grown outdoors greatly increases leaf number, total leaf area, and total plant dry weight compared to nonshaded seedlings, suggesting that commercial nurseries can improve production of containerized pawpaw seedlings using a shading regime outdoors.", "attrs": { "block_label": "abstract" }, "children": [ { "id": "p1.4.1", "order": 8, "type": "form_field", "bbox": { "l": 261.06, "t": 683.04, "r": 273.06, "b": 671.04 }, "text": "", "attrs": { "field_kind": "radio", "label": "}C\\ (5.0\\ ^{", "source": "glyph_estimate", "bbox_estimated": true, "label_source": "parent_text", "label_ref": "p1.4", "text_offset": 579, "text_span": 1 }, "reading_order": 0 }, { "id": "p1.4.2", "order": 9, "type": "text", "bbox": { "l": 148.56, "t": 683.04, "r": 590.4, "b": 458.88 }, "text": "⁻³", "attrs": { "inline": true, "text_offset": 1074, "text_span": 8, "bbox_estimated": true }, "reading_order": 1 }, { "id": "p1.4.3", "order": 10, "type": "text", "bbox": { "l": 148.56, "t": 683.04, "r": 590.4, "b": 458.88 }, "text": "³", "attrs": { "inline": true, "text_offset": 1097, "text_span": 8, "bbox_estimated": true }, "reading_order": 2 }, { "id": "p1.4.4", "order": 11, "type": "text", "bbox": { "l": 148.56, "t": 683.04, "r": 590.4, "b": 458.88 }, "text": "⁻³", "attrs": { "inline": true, "text_offset": 1191, "text_span": 8, "bbox_estimated": true }, "reading_order": 3 }, { "id": "p1.4.5", "order": 12, "type": "text", "bbox": { "l": 148.56, "t": 683.04, "r": 590.4, "b": 458.88 }, "text": "³", "attrs": { "inline": true, "text_offset": 1214, "text_span": 8, "bbox_estimated": true }, "reading_order": 4 }, { "id": "p1.4.6", "order": 13, "type": "text", "bbox": { "l": 148.56, "t": 683.04, "r": 590.4, "b": 458.88 }, "text": "⁻¹", "attrs": { "inline": true, "text_offset": 1278, "text_span": 8, "bbox_estimated": true }, "reading_order": 5 } ], "reading_order": 3 }, { "id": "p1.5", "order": 14, "type": "text", "bbox": { "l": 236.64, "t": 443.52, "r": 594, "b": 182.4 }, "text": "The pawpaw is a native North American tree fruit that has potential for use as a new high-value fruit crop or in landscapes (Layne, 1996; Pomper et al., 1999).

Seedlings grown in Roottrainers should be transplanted when the seedling has produced about 10 leaves, otherwise seedlings may set a terminal bud and stop growing for that season (author, unpublished). When growing pawpaw seedlings or transplanting them, use tall containers of 3.8 to 7.6 L (1 to 2 gal) volume, such as Treepots (Stuewe and Sons, Inc., Corvallis, Ore.), to accommodate the developing taproot. In a greenhouse experiment, stratified seed was sown into Pro-Mix BX potting medium (Premier, Red Hill, Pa.) containing Osmocote 14–14–14 (Scotts Co., Marysville, Ohio) at 1.85 kg·m⁻³ (3.118 lb/yard³) or 3.70 kg·m⁻³ (6.236 lb/yard³) in 3.8-L containers of three different heights (short, medium, and tall) (Table 1).

Because fertilizers such as Osmocote release nutrients slowly, they eliminate the need for labor-intensive liquid fertilization that may lead to excessive nutrient leaching and contamination of ground water (Nelson, 1998). Osmocote, alone or in combination with water-soluble fertilizer, was used to successfully produce pawpaw seedlings. Osmocote 14–14–14 incorporated into Pro-Mix BX potting substrate can be used effectively as the sole fertilizer source at a treatment rate of 2.22 kg·m⁻³ in containerized production (Pomper et al., 2002c).

Low to moderate shading of pawpaw seedlings grown outdoors greatly increased leaf number, total leaf area, and total plant dry weight compared to nonshaded seedlings, indicating that commercial nurseries can improve production of containerized pawpaw seedlings by using a shading regime outdoors. If plants are produced on a gravel container pad, higher levels of shading (>55%) that would also reduce air temperatures could be beneficial. Shading of field-planted pawpaw trees has been suggested to assist in the establishment of young trees (Layne 1996). Trees that are taller than 0.46 m (1.5 ft) do not require shading the first year, but trees should be provided irrigation to enhance establishment (author, unpublished).", "reading_order": 4 }, { "id": "p4.6", "order": 6, "type": "heading", "bbox": { "l": 264.72, "t": 774.48, "r": 383.76, "b": 746.88 }, "text": "Copper compounds in containers", "attrs": { "block_label": "paragraph_title" }, "level": 3, "reading_order": 5 }, { "id": "p4.7", "order": 7, "type": "text", "bbox": { "l": 264.24, "t": 741.36, "r": 427.92, "b": 322.8 }, "text": "A serious problem with transplanting container-grown trees is poor root development (i.e., circled, matted, and kinked roots), which is associated with increased tree mortality (Nichols and Alm, 1983). A water based latex paint containing cupric hydroxide[p4.7.1] has been used in commercial nurseries to treat the interior surface of containers and successfully reduce root spiraling in several tree species (Ruter, 1994). Root elongation is inhibited when root tips encounter copper compounds in paint applied to container walls, causing lateral branching from older root regions more distant from the root tip and the formation of a more fibrous root system and a lower root:shoot ratio (Arnold and Struve, 1989, 1993; Arnold and Young, 1991). Pomper et al. (2002a) reported that application of[p4.7.2] to the interior of Roottrainers did not promote development of a more fibrous root system in pawpaw seedlings, based on failure of copper compound to increase lateral root dry weight production (Pomper 2002a). Seedlings also showed yellowing of leaves and reduced chlorophyll levels by the end of the experiment in shaded plants, suggesting that the plants were suffering from copper toxicity. The use of larger containers and lower concentrations of[p4.7.3] compared to those used by Pomper (2002a) might reduce plant copper toxicity problems and stimulate lateral branching of seedling root systems.", "children": [ { "id": "p4.7.1", "order": 8, "type": "text", "bbox": { "l": 264.24, "t": 741.36, "r": 427.92, "b": 322.8 }, "text": "[Cu(OH)₂]", "attrs": { "inline": true, "text_offset": 255, "text_span": 8, "bbox_estimated": true }, "reading_order": 0 }, { "id": "p4.7.2", "order": 9, "type": "text", "bbox": { "l": 264.24, "t": 741.36, "r": 427.92, "b": 322.8 }, "text": "Cu(OH)₂", "attrs": { "inline": true, "text_offset": 797, "text_span": 8, "bbox_estimated": true }, "reading_order": 1 }, { "id": "p4.7.3", "order": 10, "type": "text", "bbox": { "l": 264.24, "t": 741.36, "r": 427.92, "b": 322.8 }, "text": "Cu(OH)₂", "attrs": { "inline": true, "text_offset": 1256, "text_span": 8, "bbox_estimated": true }, "reading_order": 2 } ], "reading_order": 6 }, { "id": "p4.8", "order": 11, "type": "text", "bbox": { "l": 264.48, "t": 323.04, "r": 427.2, "b": 178.56 }, "text": "In conclusion, recent studies have allowed the development of recommendations (e.g., potting substrate type, fertilizer regime, the use of tall containers to accommodate the seedling’s strong tap root, bottom heating, and shading regime) toward successful container production of pawpaw.
