ABSTRACT Drought is a major threat worldwide for crop production, especially due to the rapid climate changes. Current drought solutions involve improving irrigation system, rainwater harvesting, damming, cloud seeding, and changes of cultivation methods. Despite effective, each solution has economic, environmental, and temporal drawbacks. Among all solutions, the most effective, inexpensive and manageable method is the use of drought-tolerant cultivars via plant breeding. However, conventional plant breeding is a time-consuming and laborious task, especially for phenotypic data acquisition of target traits of numerous progenies. High-throughput phenotyping (HTP) is a recently developed method and has potential to overcome the mentioned issues. HTP offers massive, accurate, rapid, and automatic data acquisition in the breeding procedure and can be a breakthrough for developing drought resistant/tolerant cultivars. This study introduces various methods of HTP to detect drought stress, which can accelerate the breeding processes of drought-tolerant cultivars to provide helpful guidelines for breeders and researchers to choose appropriate methods.

RESUMO Devido ao aquecimento global, em Seul na Coreia do Sul, é plausível plantar árvores de folhagem perenes no inverno frio, oferecendo opções para criar um ambiente verde. Assim, é válido investigar quais tipos de plantas de folhagem perene poderiam sobreviver em Seul durante o inverno. Neste estudo, escolheu-se a hera-inglesa (Hedera helix), planta nativa da Europa utilizada como ornamental. Ela cresce em condições de temperaturas moderadas. Neste trabalho, investigou-se H. helix, uma planta de cobertura perene ao longo do inverno, a fim de avaliar a possibilidade de utilizar esta espécie em Seul. Descobriu-se que H. helix pode sobreviver durante o inverno em Seul. Isso significa que ela pode ser utilizada para criar um ambiente perene em Seul. Isto também implica que similares tipos de plantas poderiam ser testados assumindo que o ambiente em Seul está se tornando mais adequado para as plantas originadas de lugares quentes. Isto nos proverá maiores opções para elaborar ambientes ao ar livre na cidade que não é tão arborizada.

ABSTRACT Due to the global warming, Seoul in Korea seems to be plausible to grow evergreen broad-leaved trees over the cold winter. This offers the planting options to create green environment. Thus, it became worth investigating what kinds of evergreen broad-leaved plants could stand in Seoul during the winter. Ivy (Hedera helix) has been chosen in the current study which is a well-known native and ornamental plant in Europe. It grows in warm condition in general. The current study tracked H. helix which is evergreen cover plant over winter in order to evaluate the possibility for utilizing this species as a climber or cover-plant in Seoul. We found that H. helix can survive over the winter and can be utilized to create evergreen environment in Seoul. It also implies that similar kinds of plants could be tested assuming the environment of Seoul is becoming more suitable for the plants originated from the warmer sites. H. helix is an option for elaborating outdoor environments in the city that lacks of green color.
