Abstract

Strawberry (Fragaria spp.) has a high economic value and various benefits, but the production of strawberry plants in Indonesia is still low in terms of both quantity and quality. Strawberry plant breeding can be done in various techniques, one of which is polyploidization. Polyploidization by an induction of colchicine at various concentrations in strawberry crops cv. California and Festival resulted in superior phenotype characteristics. To prove the existence of a change in ploidy in strawberry, then research at the molecular level needs to be done. The purposes of this study were to find out changes in ploidy of strawberry plants using CAPS molecular markers and to detect the polymorphism in strawberry plants quickly. The samples used were young leaves. Main procedure was the cutting of the amplified DNA using restriction enzymes of TaqI and HaeIII. The results showed that CAPS molecular markers were capable of detecting polymorphism quickly and efficiently in strawberry plants. Specific bands among strawberry plants having undergone polyploidization and those not having undergone polyploidization can be seen on the differences in monomorphic or polymorphic bands between the control plants and treated plants.

Abstract

The current study is designed to investigate vocabulary teaching strategies/activities employed by teachers in Islamic senior high schools by referring to the principle of the Four Strands proposed by Nation (2007). A survey research design was used in line with the study's goal. English teachers who teach in Islamic senior high schools or Madrasah Aliyah, both public and private schools in West Sumatera, were the study's target demographic. The questionnaire and interviews collected the information required to respond to the survey's question. The finding reveals that teachers employ four kinds of strategies/activities following the Four Strands by Nation (2007) in teaching vocabulary to students. The findings of the study suggest that this study might give an insight that more strategies/activities need to be done by teachers to enhance vocabulary learning. The findings of the study provide some implications for future practice in teaching-learning process of teaching vocabulary. In reference to the findings, the recommendations are addressed to EFL teachers and future researchers. Some implications of the study are also discussed.
