Following spring planting in 1998, and for four seasons (1998–2001), early growth and development were characterized for seven grafted [PawPaw Foundation (PPF), Frankfort, Ky.) pawpaw Regional variety trial (PRVT) rootstock] pawpaw (Asimina triloba) varieties, ‘Davis’, ‘Taylor’, ‘Rebecca’s Gold’, ‘Sunflower’, ‘Overleese’, ‘Prolific’, ‘Wells’, and one nongrafted seedling strain. Survival rate after four seasons was 96.5% for grafted trees and 100% for seedling trees. Entries exhibited significant differences in total height, trunk cross-sectional area (TCSA), average shoot length, first winter cold injury and percent bloom. By the end of 2000, seedling tree height and TCSA were greater as compared to the named varieties. Seedling height averaged 134 cm (52.8 inches), with a TCSA of 4.54 cm² (0.704 inch²), while the least vigorous variety (Davis) had an average height of 77 cm (30.3 inches) and a TCSA of 1.54 cm² (0.239 inch²). Average shoot length was significant only in the year of planting, ranging from 39.3 cm (15.47 inches) for ‘Davis’, to 61.3 cm (24.13 inches) for ‘Sunflower’. Tip dieback occurred in the winter following planting on all varieties; this damage ranged from 23.3% (“Taylor”) to 73.4% (“Overleese”). In 1999, lower axillary shoots (LSL) breaking below the damaged tips grew longer [31.1 to 50.6 cm (12.24 to 19.92 inches)] than upper distal axillary shoots (DASL) [15.8 to 44.6 cm (6.22 to 17.56 inches)], indicating a lack of apical dominance and vigor of emerging top buds. All named varieties developed flower buds by the spring of the fourth season, with budding ranging from an average of 0.5 buds/tree (“Rebecca Gold”) to 6.0 buds/tree (“Prolific”). Viability of these buds as determined by successful anthesis ranged from 0.4% (“Davis”) to 63.8% (“Wells”).

Soil nutrient and physical parameters were measured 15 Apr. 1997. Soil test results were pH-5.9; phosphorus 30.3 kg·ha[p2.4.4] (27 lb/acre); potassium 214.1 kg·ha[p2.4.5] (191 lb/acre); organic matter 2.2%; cation exchange capacity 16.6 meq; all micronutrients in standard ranges.

Early bud break number from the original grafted whip and resulting primary scaffold development (no. three tiers) were also noted. Length of the longest shoot (LSL) and the most distal axillary shoot (DASL) were recorded in 1999 as an indication of relative apical dominance following the loss of the terminal shoot to cold damage. Overwinter damage was quantified by the length of dieback in the first-year whip (FYWD) in Spring 1999 and third-year terminal dieback (TYTD) in Spring 2001. Damage was expressed as the length of dieback and the percentage of the shoot length with dieback. TCSA at 20.3 cm (10.2 to 15.2 cm above the graft), maximum tree spread, and number and percentage of shoots longer than 30.4 cm were recorded for each tree in Spring 2001. The number of floral buds present were counted on 18 Apr., and at anthesis (no. of open blooms) on 27 Apr. and 9 May 2001.", "reading_order": 9 }, { "id": "p2.11", "order": 24, "type": "text", "bbox": { "l": 431.28, "t": 124.32, "r": 593.52, "b": 79.2 }, "text": "All data were analyzed using analysis of variance with CoStat 6.1 (CoHort Software, Monterey, Calif.).
