This research was carried out to investigate seed germination and growth of the perennial plant Apocynum lancifolium under different NaCl concentrations, with a view for future cultivation on reclaimed land. Initial characterization revealed that the average length and weight of A. lancifolium seed pods was 133.6 mm and 0.23 g, respectively, and the thousand-grain weight was 0.59 g. Upon examining the effects of light on seed germination, we found germination to be 1.7% higher under light conditions (90%) than under dark conditions (88.3%). In terms of the response to salt stress, we found that 90% of seeds germinated in the 0.00%, 0.25%, and 0.50% salt treatment groups. Although salt treatment up to a concentration of 0.5% was found to have little effect on seed germination, the rate of germination decreased at higher concentrations and was completely inhibited in the 2% treatment. We also established that germination rates were higher in seeds sown in horticultural topsoil than in the coarse sandy soil found in the plant’s natural habitats. Although the growth of A. lancifolium tends to decrease with an increase in salt concentration, we found that the stem thickness, fresh weight, and dry weight of A. lancifolium seedlings subjected to 0.25%–1.0% salt were comparable to those of the control seedling that were not exposed to salt. Furthermore, in contrast to those plants subjected to 2.0% salt, these plants continued to grow and remained viable.
본 프로그램은 저소득 결손가정 아동을 대상으로 원예활동 및 그림그리기 병행활동을 실시하여 정서증진의 기회를 제공하고, 이를 통해 주의력을 향상시키고자 실시하였다. K-HTPF 및 매 회기별 대상자의 그림을 통해 사회성, 안정감, 역동성 및 표현력 등이 증진되었음을 볼 수 있었다. 또한 주의집중력 향상을 살펴보기 위한 ADS 검사결과에서는 충동성 점수가 낮아지고, 일관성이 높아진 결과를 통해 아동의 주의집중력이 향상되었음을 확인할 수 있었다. 앞으로 정서발달 및 주의집중력에 관한 신뢰도를 확보하기 위한 원예활동연구를 추가 수행할 예정이다.
