Abstract

In strawberry (Fragaria ×ananassa), initial bare-root crown diameter and early-season flower cluster removal have been two factors suspected of influencing fruit yield and size. This study evaluated the effect of these two factors on the day-neutral strawberry varieties Monterey and Cabrillo. Bare-root crowns with three different diameters were categorized into small (< 0.5 cm), medium (> 0.5 to 1 cm), and large (> 1 cm) at planting. Each of the crown diameter treatments was split into two plots for flower removal or no flower removal in the early season and data on canopy diameter, fruit yield, and fruit size collected in the subsequent months of production. The study was conducted over two growing seasons (2019–20 and 2020–21). No difference was found in plant canopy diameters measured in February, ∼3 months after planting, between any of the treatments in either year. Although early-season flower removal and some crown sizes resulted in lower fruit yield in March and April, none of these treatments resulted in any fruit yield or size differences in subsequent months nor in season end totals.

日中性草莓初始裸根冠大小和早季花束去除对后续植株性能影响不大
在草莓(Fragaria×ananassa)中,初根冠直径和早季花簇去除是影响果实产量和大小的两个因素。本研究评估了这两个因素对日中性草莓品种蒙特利和卡布里洛的影响。在种植时,将三种不同直径的裸根冠分为小冠(<0.5 cm)、中冠(>0.5至1 cm)和大冠(>1 cm)。将每种树冠直径处理分为两个地块,在早季进行除花或不除花,并在随后的生产月份收集树冠直径、果实产量和果实大小的数据。这项研究在两个生长季节(2019-20年和2020-2021年)进行。在种植后的2月~3个月,在任何一年的任何处理之间,都没有发现植物冠层直径的差异。尽管早季移花和一些树冠大小导致3月和4月的果实产量较低,但这些处理都没有在随后的几个月或季末总产量中产生任何果实产量或大小差异。
