摘要

The white strawberry (Fragaria chiloensis) has great potential as an alternative product with excellent organoleptic quality. However, this species bears only one inflorescence per year, so productivity is very low (4-6 t ha1). In red strawberry (Fragaria x ananassa), the morphology, plant architecture model and flower physiology are well known, while in the case of the white strawberry these topics have been little studied and apparently it would have a different behavior. Based on this background,we carried out a phenotypic characterization of Chilean white strawberry (F. chiloensis subsp. chiloensis f. chiloensis) and Chilean wild form [F. chiloensis subsp. chiloensis f. patagonica). To evaluate induction and floral differentiation, we performeda meristematic analysis during the winter rest (June) and early spring (September). Finally, we observed the flowering under greenhouse conditions (November). In June, both accessions had differentiated only the apical meristem of the main shoot. In early September, the Chilean white strawberry maintained its initial condition, whereas the wild form showed more shoots, which were developed from axillary buds. These axillary shoots also were flower differentiated in the terminal meristem. The phenotypein greenhouse was congruent with these observations. The Chilean white strawberry only developed one shoot (crown) per plant with one inflorescence during the season, while wild strawberry developed 10-15 secondary and tertiary shoots per plant, each with its own terminal inflorescence. Results indicated that Chilean white strawberry flower differentiated only the apical meristem in inductive condition. Therefore, likely an apical dominance effect and heavy bud dormancy may limit the formation of the lateral shoots, finally determining a very low production potential, while in the Chilean wild form the apical dominance is lower and the branching capacity is higher.

Chiloensis subsp。 Chiloensis f。 patagonica)。为了评估诱导和花卉分化,我们在冬季休息(六月)和早春(9月)期间进行了共同分析。最后,我们观察到温室条件下的开花(11月)。 6月份,两个换乘只有主要拍摄的顶端单位。 9月初,智利白色草莓保持其初始条件,而野生形式显示出更多的芽,这是从腋芽开发的。这些腋下芽也是在终端单位中差异化的花朵。这些观察结果的现象是一致的。智利白草莓仅在季节开发了每株植物的一个射击(皇冠),同时野草莓每株植物开发了10-15次和三级芽,每个终端花序都有自己的终端花序。结果表明,智利白色草莓花只区分了归纳条件的顶端绩效。因此,可能是顶尖的优势效应和重芽休眠可能限制横向芽的形成,最终确定非常低的生产潜力,而在智利野生形式中,顶端优势较低,分支能力较高。
