  16. 16. Benefits of Dwarfing Rootstocks •Early of cropping (precocity) • Shorter time to payback initial investment •Improved yield/unit land area (productivity) • Annual profitability •Reduced tree size (dwarfing level) • Ease and cost of spraying • Ease and cost of picking • Ease and cost of pruning

  18. 18. Current Apple Rootstocks: • Currently in the United States the most common apple rootstocks are M.9, M.26, B.9. • 60% of the rootstocks are M.9, • 20% are B.9, • 10% are M.26, • 4% are M.7, • 3% are MM.111 • In China most apple rootstocks are seedling
  19. 19. Challenges with Current Apple Rootstocks: • Over the last 60 years, growers worldwide have used the Malling series of rootstocks from England. However their limitations are: • lack of winter hardiness, • lack of resistance to Phytophthora root rot, • susceptibility to fire blight bacterial disease, • burrknots, • poor anchorage, • root suckers, • sensitivity to apple replant disease, • brittle graft unions. • lack of precocity.
  20. 20. The Geneva Apple Rootstock Breeding and Development Program Joint Program with USDA and Cornell University Dr. Gennaro Fazio, Herb Aldwinckle and Terence Robinson Goal: Produce a series of rootstocks which are resistant to important rootstock diseases and insects that are dwarfing, productive and efficient. • Resistance to fire blight • Resistance to Phytophthora root rot • Resistance to woolly apple aphid • Cold tolerant • Resistant to apple replant disease.

  37. 37. Brookfield Gala/G.41 New York State 10 branches at planting (2006) 40 fruits in the second leaf (2007) With the Tall Spindle we can achieve high early yields with highly feathered trees.
  38. 38. The Potential Fuji/CG.007 85 fruits/tree in the second leaf X 3374 trees/ha = 43 t/ha
  39. 39. Managing Feathered Trees With the Tall Spindle we suggest removing 1-2 of the most vigorous feathers at planting and tying the rest below horizontal soon after planting.
  40. 40. Up to 3 feathers can be removed With Whips, tree should not be headed.
  41. 41. 促进早产的策略 -定植时不进行修剪 (除了去除过大的侧枝以外) -定植后尽快将侧枝压倒水平线以下

  46. 46. Common Error: Excessive crop load in the 2-4th Years We use a strict program of crop load management in the first 5 years.

  47. 47. Concepts of Pruning – Limb Renewal Pruning
  48. 48. Common Error: Allowing large branches to remain in the tree Large upper branches cause shade on lower canopy Large branches export carbohydrates to trunk and root system.

  50. 50. Simple Recipe for Pruning Mature Tall Spindle Trees 1. Limit height by cutting leader to a fruitful side branch at optimum tree height 2. Remove 2-3 branches per year larger than 2cm (2 cut rule) – Remember "large branches create large trees” 3. “Columnarize” or simplify each remaining branch so that it has a single axis and is left long and pendant
  51. 51. • High fruit quality requires good light distribution and calm trees. • Limb renewal pruning is the single most important pruning concept for mature high density orchards. • Large limbs lead to large root systems and greater tree vigor. Pruning concepts of Large Fuji Trees
  52. 52. Removal of large limbs should be done over a 3 year period
  53. 53. Mature Tree Canopy Management • "The best way of restricting vegetative growth is to produce apples." • Use Nutrition to achieve calm tree growth. • Use Pruning to open gaps in the canopy without stimulating vigor. • Remove 2-3 large branches (diam.~4cm) each year. Do not shorten other branches. Allow them to become pendant before shortening. • Modify summer pruning to allow replacement branches to develop on the trunk.
  54. 54. After Several Years of Renewal Pruning the tree has few large branches
  55. 55. Precision V-Trellis Benefits - high tree densities, high mature yields, systematized pruning, adaptable to platforms, less expensive tree, adaptable to platfomrs, reduced sunburn. Negatives points – Costly trellis, costly tree training and development, complicated management.
  56. 56. Super Spindle Benefits - high tree densities, high early productions, simple pruning, high fruit quality, adaptable to platforms. Negative Points – High investment, excessive vigor in the top, requires low tree costs, not more profitable than lower densities.
  57. 57. Solaxe
  58. 58. Solaxe Benefits: Control of excessive vigor, high production, low alternate bearing. Negative Points: • At densities above 2000 tr/ha the large branches in the top create shading problems of the lower canopy. • The chimney space is wasted. • The chimney does not allow shoots for renewal shoots. • High hand labor costs to do spur extinction and limb bending. • It is useful for areas with excessive vigor or semi-dwarf rootstocks.
  59. 59. Vertical Axis
  60. 60. Bi-Axis Benefits:- moderate densities but high number of leaders per acre, high yields, high fruit quality, reduced vigor in each leader, adaptable to platforms and mechanical pruning. Negative points: Requires a 2 stem tree from the nursery.
  61. 61. Bi-Axis
  62. 62. Fruiting Wall, (Mur Frutiere) Benefits include- mechanical pruning, reduction of costs, high yields high fruit quality. Negative points – vigor can be excessive, fruits size can be smaller.
  63. 63. Fruiting Wall, (Mur Frutiere)
  64. 64. • For most growers the Tall Spindle is the best. • Optimum Economic Tree Density 2,500-3,000 trees/ha • High early production 150 t/ha in first 5 years • High mature yields 75 t/ha with Fuji • High Fruit Quality thin conical canopy • Improved labor efficiency Simplified pruning recipe with partial mechanization of dormant pruning and tree training and summer side wall shearing for summer pruning. • Where vigor is too high the Bi-Axis is an option • With pears and OHF rootstocks • Where tree cost is low the Super Spindle is an option • With spur or semi-spur type varieties the Fruiting Wall is very interesting. • The Precision V- or Vertical Trellis have little potential where sunburn is a problem. Which System is Best
  65. 65. New Directions: Partial Mechanization of Dormant Pruning
  66. 66. The simple pruning recipe of the Tall Spindle is well adapted to the use of motorized platforms to reduce pruning costs - The best fruit growers in NY have reported reductions in dormant pruning labor of 25-40% if the trees are grown in the Tall Spindle system.
  67. 67. Dormant Pruning with a 2-Row Platform
  68. 68. Partial Mechanization of Dormant Pruning and Hand Thinning can Reduce Labor Costs by 25-50%
  69. 69. New Directions: Mechanical Summer Pruning with the Tall Spindle Benefits include reduction of costs, improved fruit quality. Timing: June, July, August
  70. 70. Mechanization of Summer Pruning Width 75cm Width 1.5m Goal is to have a narrow fruiting wall with good light distribution but not create a vigor response in the tree and reduce pruning costs by 2/3. With tall spindle the canopy should be an angled wall 1.5m wide at base and 75cm feet wide at top. The pruning strategy is to use mechanized pruning for 2 years then a corrective dormant pruning to remove limbs that have become too large and open up the canopy.
  71. 71. 6th Lead Fuji with Mechanical Sidewall Shearing
  72. 72. 6th Lead Gala with Mechanical Sidewall Shearing
  73. 73. • For most growers the Tall Spindle is a great system. • Optimum Economic Tree Density • High Early Production • High mature yields • High Fruit Quality • Partial Mechanization of Pruning for Improved Labor Efficiency. • Biggest mistakes are: • Initial branches not tied down • Not growing the tree to 3m height fast enough • Excessive cropping in years 2-4 • Too many large branches when trees are mature Conclusions
  74. 74. Thank you for your attention
