“…The number of runner tips did not differ significantly among source types, which highlights that it is a developmental plant variable affected mainly by photoperiod and temperature (Smeets, 1980;Sonsteby, 1997). Nevertheless, their growth differs according to source-sink relationship.…”

-The objective of this work was to determine the sink-source relationships and their effects on the number and growth of runner tips of 'Camino Real' strawberry stock plants. Three types of sources were evaluated: one defoliation at 96 days after planting (DAP), two defoliations at 50 and 96 DAP, and mother plants without defoliation. Four types of sink were accessed: runner tips collected weekly and monthly, four stolons with rooted runner tips in pots, and four freely-grown stolons. A completely randomized experimental design was used in a split-plot arrangement, with four replicates. The source types were placed in the plots, and sink types in the subplots. The number of runner tips, the crown diameter, and the dry matter mass were determined. Number and growth of tips were higher on plants without defoliation, and decreased 44.7% on twice-defoliated mother plants. The two-defoliation management did not reduce runner tip dry matter mass only on plants with rooted stolons, which produced runner tips 50% heavier. Defoliation of mother plants bearing rooting stolons can be used to reduce their growth, without reducing the emission and growth of runner tips.Index terms: Fragaria x ananassa, plug plants, propagation, sink strength, source-sink relationship. Desfolha de plantas matrizes de morangueiro para a produção de pontas de estolãoResumo -O objetivo deste trabalho foi determinar as relações dreno-fonte e seus efeitos sobre o número e o crescimento de pontas de estolões de plantas matrizes de morangueiro 'Camino Real'. Três tipos de fontes foram avaliadas: uma desfolha aos 96 dias após o plantio (DAP), duas desfolhas aos 50 e 96 DAP e plantas matrizes sem desfolha. Quatro tipos de drenos foram analisados: pontas de estolão coletadas semanal e mensalmente, quatro pontas enraizadas em vasos e quatro estolões de crescimento livre. Utilizou-se o delineamento experimental inteiramente casualizado com parcelas subdivididas e quatro repetições. Os tipos de fonte foram dispostos nas parcelas, e os tipos de dreno, nas subparcelas. Foram determinados o número de pontas, o diâmetro de coroa e a massa de matéria seca. O número e o crescimento das pontas foram mais elevados nas plantas sem desfolhamento, e diminuíram 44,7% nas plantas matrizes com duas desfolhas. As duas desfolhas não reduziram a massa de matéria seca das pontas apenas nas plantas com estolões enraizados, as quais produziram pontas 50% mais pesadas. A desfolha das plantas matrizes com estolões enraizados pode ser usada para reduzir-lhes o crescimento, sem reduzir a emissão e o crescimento das pontas de estolão.Termos para indexação: Fragaria x ananassa, mudas em bandejas, propagação, força de dreno, relação fonte-dreno.

“…UG çileklerinde çiçek oluşumu genel olarak yalnız UG şartlarında meydana gelir (Darrow ve Waldo, 1934). Ancak bu grubun bazı çeşitlerinde hem uzun hem kısa fotoperiyotlarda çiçeklenme meydana gelebilmektedir (Downs ve Piringer, 1955;Smeets, 1979). Bunlarda salkım gelişimi ise KG çileklerine benzer şekilde yalnız uzun fotoperiyotlarda gerçekleşmektedir (Downs ve Piringer, 1955;Kono ve Tusunematsu, 1990).…”

Çilekler fotoperiyot isteklerine göre kısa gün, uzun gün ve gün-nötr çilekleri olarak sınıflandırılırlar. Günümüz modern çilek çeşitlerinin çoğu kısa gün çeşitleridir. Ancak derim periyodunu uzatmadaki önemleri nedeniyle son yıllarda gün-nötr çeşitlerinin de ticari yetiştiricilikte kullanımı artmaya başlamıştır. Kültür çileklerinin karmaşık çiçeklenme karakterleri bunların çiçeklenme fizyolojisinin öğrenilmesini geciktirmiş, bu konu günümüzde bile halen merak edilen ve üzerinde durulan bir konu olmuştur. Kısa, uzun ve gün-nötr çileklerinin çiçeklenme fizyolojilerinin ve buna etki eden faktörlerin iyi bilinmesi bunların yetiştiriciliklerindeki başarıyı artıracak, çilek yetiştiriciliğinin gelişimine katkıda bulunacaktır.

We assessed runner production in everbearing strawberry cultivars (Fragaria × ananassa Duch.) 'Natsuakari' and 'Dekoruju', which exhibit poor ability to produce runners, thus limiting their propagation and use. Both cultivars required 1,000 h of chilling (< 5°C) to induce runner production when grown under a long day length (LD); however, they required longer chilling under a short day length (SD). Plants chilled for 2,000 h tended to produce more runners under SD than under LD. During spring and summer, the overwintered 'Natsuakari' plants produced the fewest runners under SD. In contrast, the overwintered 'Dekoruju' plants produced the fewest runners under LD. Thus, a longer day length did not always enhance runner production in these cultivars. In autumn, 90-day cold storage at -2°C was substituted for natural chilling for plants that were rooted in summer. For both cultivars, the production of runners by plants that were rooted in July was similar to or greater than that by plants that were rooted in May. The rooting of mother plants in July, which are more available than plants rooted in May, did not have a detrimental effect on runner production during the next early summer period. Considering total runner production till July, we concluded that it is appropriate to initiate cold storage in December for the 'Natsuakari' cultivar and in November or December for the 'Dekoruju' cultivar.
