摘要

传统上,建立果园的成功与否取决于所使用苗圃植物的活力。本研究旨在评估两种甜樱桃(Prunus avium L.)栽培品种('Lapins'/'Colt'和'Regina'/'Gisela 12')的移栽后存活率、树冠生长和果实产量,这两种栽培品种的径向基部体积分别为 100%、50% 和 25%,苗圃类型分别为 (i) 裸根 (BR) 或 (ii) 套袋 (B)。嫁接到'Colt'砧木上的植株与嫁接到'Gisela 12'上的植株相比,其初始根量是后者的两倍。在智利中央山谷的三个商业果园进行了三季评估。结果表明,根量和苗圃类型并不影响植物的存活率和产量。对于'Regina'/'Gisela 12',只有袋栽处理导致树干横截面积(TCSA)和枝条长度减少,而对于'Lapins'/'Colt',BR25 处理的初始 TCSA 低于其他处理,但对产量没有负面影响。因此,关于根量和植株类型对甜樱桃在'Colt'和'Gisela 12'砧木上成功栽培的影响的推测可以放弃了。果园的成活、生长和早熟更多地取决于种植后的条件和水分管理,而不是苗圃植物根系的数量或类型。为了果园达到最佳健康状态,必须优先考虑适当的种植后护理和水分管理。

Reduced Root Volume at Establishment, Canopy Growth and Fruit Production in ‘Lapins’/‘Colt’ and ‘Regina’/‘Gisela 12’ Sweet Cherry Trees
The success of establishing fruit orchards has traditionally been attributed to the vigor of the nursery plant used. This study aimed to evaluate the post-transplant survival, canopy growth and fruit productivity of two sweet cherry (Prunus avium L.) cultivars (‘Lapins’/‘Colt’ and ‘Regina’/‘Gisela 12’) with different radicular basal volumes of 100%, 50% and 25% and nursery plant types: (i) bare root (BR) or (ii) bagged (B). The initial stem diameter of the plants ranged from 12 to 19 mm, and their height ranged from 1.4 to 1.8 m. Plants grafted onto ‘Colt’ rootstock exhibited twice the initial root volume compared to those grafted onto ‘Gisela 12’. Evaluations were carried out in three commercial orchards during three seasons in the Central Valley of Chile. The results indicated that root volume and nursery type did not affect plant survival and productivity. For ‘Regina’/‘Gisela 12’, only the bag treatment resulted in less trunk cross-sectional area (TCSA) and shoot length, and for ‘Lapins’/‘Colt’, the BR25 treatment showed a lower initial TCSA than other treatments, although without a negative effect on yield. Hence, the presumption about the influence of root volume and plant type on the successful establishment of a sweet cherry on ‘Colt’ and ‘Gisela 12’ rootstock can be discarded. The survival, growth and precocity of the orchard depend more on post-planting conditions and water management than on the number or type of nursery plant roots. It is important to prioritize proper post-planting care and water management for optimal orchard health.
