  • In the present study, we investigated the effects of artificial removal of corolla and calyx lobes from open flowers on fruit development and fruit quality of strawberry (Fragaria ${\times}$ ananassa Duch.). Removing the corolla had no significant effect on fruit weight, hardness, length, and diameter, Hunter L, a, b values, sugar content and acidity. However, removing the calyx lobes significantly inhibited longitudinal and transverse growth of the fruits, resulting in diminished fruit size. In addition, merchantable fruit quality significantly decreased upon removing the calyx lobes, and this tendency was increased as more calyx lobes were removed. Nonetheless, removal of the calyx lobes had no effects on fruit color, sugar content, or acidity, similar to the effect of corolla removal.

  • Polymorphic bands of two fine-leaf zoysiagrass mutants (CNU 70-1, CNU 70-2) induced via a gamma-ray irradiation on seeds of Zoysia japonica were obtained by using randomly amplified polymorphic DNA (RAPD) primers. The genotype-specific fragments were then converted into PCR-based sequence characterized amplified region (SCAR) markers, which are now amenable to detecting them among other zoysiagrass species widely noticeable in Korea. The CNU 70-1-specific primer set amplified about 900 bp successfully, while the CNU 70-6 marker produced the expected 1,500 bp band, by which those markers were nominated by CNU 70-1_900 and CNU 70-6_1500 SCARs, respectively. The developed SCAR markers can be an applicable tool in sod industry where illegal appropriation hampers breeder's right and profits due to the turfgrass plant vegetatively propagating.
