ABSTRACT.
The objective of this work was to test a closed soilless growing system for producing bare root transplants and runner tips of two strawberry clones, using two categories of substrates. The system used corrugated roofing panels of fiber-cement, over which a substrate layer was used as a growing bed. The nutrient solution was pumped from a reservoir toward the upper end of the roofing panels and drained back to a reservoir. Plant growth and development were determined for two advanced strawberry clones, grown in sand or in Plantmax organic substrate. Growth of the stock plants and the number and dry mass of bare root transplants were similar in the substrates, but bare roots differed in their crown diameters by substrate. For number of runner tips, no significant differences were found in total, small, and medium categories in the substrates. A mean production of about 590 runner tips per square meter and 145 bare root transplants per square meter was obtained. For both clones, a large number of bare root transplants and runner tips of adequate size were produced in the closed soilless growing system using sand or organic substrate.

RESUMO.
O objetivo deste trabalho foi testar um sistema fechado de cultivo sem solo, para a produção de mudas e pontas de estolões de dois clones de morangueiro, com uso de duas categorias de substrato. O sistema foi constituído por um leito de cultivo formado por telhas de fibrocimento, com uma camada de substrato como leito de cultivo. A solução nutritiva foi bombeada de um reservatório até a extremidade mais alta da telha e drenada de volta ao reservatório. Foram determinados o crescimento e o desenvolvimento de dois clones avançados de morangueiro, plantados na areia e no substrato orgânico Plantmax. O crescimento das plantas matrizes foi similar nos dois substratos. O número e a massa de matéria seca das mudas de raízes nuas foram semelhantes nos dois substratos, mas diferiram nos diâmetros de coroa. Quanto ao número de pontas de estolões, não foram observadas diferenças significativas nas categorias pequena e média e no total, em ambos os substratos. Foram obtidas produções médias de 590 pontas de estolão por metro quadrado e 145 mudas de raízes nuas por metro quadrado. A produção de um alto número de mudas com raízes nuas e de pontas de estolão de morangueiro, com tamanho e peso adequados, pode ser realizada no sistema fechado sem solo, com uso de substratos inertes ou orgânicos.

Abstract :Lotus corniculatus L. is the most important agricultural species in the genus Lotus and is the most widely distributed Lotus species worldwide. L. corniculatus genotypes form complex groups that are difficult to recognize both morphologically and biochemically. Given the extensive and expensive process of isolating Simple Sequence Repeats (SSR, also called microsatellites), the possibility of using microsatellites already identified in related species is highly attractive. The aim of this work was the identification and validation of transferable microsatellite markers in L. corniculatus, and using those markers to study the genetic variability among four cultivars. Each cultivar of L. corniculatus was represented by 15 genotypes. Ten microsatellite markers were evaluated, and from those, four were selected based on their discriminative values observed among cultivars. We detected 29 alleles for the four markers, and there was an average of 7.25 alleles per locus. The marker TM0197 had the fewest number of alleles (5) and TM0083 had the highest number of alleles (10). The polymorphic information content (PIC) for the selected markers varied from 0.19 to 0.35, and the markers were therefore classified as highly informative. Based on the markers, we found high variability between individuals of the same cultivar. The use of transferable microsatellite markers could be useful to differentiate individuals at a relatively low cost, showing a great potential for use in breeding programs.
