The purpose of the study is to assess morphological and chromosomal comparison of Mini type Phalanopsis ‘KS Little Gem’ and four domestic market available cultivars (‘Queen Beer’, ‘Tony Pink’, ‘Vaviche’ and ‘Rorens’). ‘KS Little Gem’ had the highest number of leaves (14.9), while the other four types had fewer than ten. The longest leaf length was 21.5㎝ for ‘Tony Pink’, followed by 16.2㎝, 18.0㎝ and 17.5㎝ for ‘Queen Beer’, ‘Rorens’ and ‘Vaviche’ respectively. The length and width of the petals of ‘KS Little Gem’ were 29.5㎜ and 25.6㎜ respectively indicating a round shape flower compared to other cultivars. When the flower lifespan of ‘KS Little Gem’ was compared to four cultivars of the domestic market, it was found that it had a 123-day shelf life, which was twice longer than that of the four cultivars. According to chromosome analysis ‘KS Little Gem’, ‘Rorens’, ‘Tony Pink,' and ‘Vaviche’ were tetraploid (2n = 4x = 76) while ‘Queen Beer’ was diploid (2n = 2x = 38). The estimated DNA content of ‘KS Little Gem’, ‘Rorens’, ‘Tony Pink’ and ‘Vaviche’ had 4918.4, 4794.2, 4705.2 and 4964.3 Mbp respectively, which were roughly double than that of P. cornu-cervi (control, 2n = 2x = 38). However, ‘Queen Beer’, had an estimated DNA content of 2802.2Mbp, similar to that of P. cornu-cervi. The morphological features, genome size and chromosomal data reported in these studies can be used by breeders to create more efficient Phalaenopsis breeding programs.

A new Phalaenopsis cultivar, ‘Yellow Green’, was bred at Kangsan Orchid, Korea. The new cultivarhas small, deep-yellow flowers with a red lip, and was introduced by artificial crossing of thePhalaenopsis cultivar ‘Sogo Pride F-1016’ and the Phalaenopsis cultivar ‘Tzu Ching Glint’. Theelite individual KS-752-1, later named as ‘Yellow Green’, was selected among 300 individualprogenies through over three years (2008-2010) of intensive selection for excellent vegetative andflowering characteristics. In the 1st (2011-2013) and 2nd (2014-2015) years of breeding, characteristicanalysis was performed through stability and uniformity tests. ‘Yellow Green’ has flowers that aredeep-yellow (RHS#: 5A) with a red lip (RHS#: N74A) and are small in size, measuring 4.6 cm inlength and 4.9 cm in width. The flowers are light-green at the beginning and gradually turn todeep-yellow. Also, the flower buds are produced easily. ‘Yellow Green’ flowers are a compoundraceme type, suitable for pot cultivation. Its leaves grow horizontally and are about 17.5 cm inlength and 6.2 cm in width. This cultivar is characterized by the absence of genetic variation, fast invitro propagation, and vigorous growth that facilitates cultivation. This cultivar was registered(Reg.#:6268) with the Korea Seed & Variety Service (KSVS) on July 18, 2016, and the plantbreeder's right is currently owned by the Kangsan Orchid Company, Korea.

Phalaenopsis ‘KS Little Gem’ is a new cultivar with superior ornamental qualities. Newly produced cultivars are often studied to determine the optimum growing conditions, as production management practices vary within species. We focused on the effects of temperature and fertilizer application on the growth and carbohydrate content of ‘KS Little Gem’ plantlets. Two-month-old plantlets were subjected to different temperatures (20, 25, and 30°C) and fertilizer rates (0.33, 0.5, and 1 g・L-1) inside a growth chamber. Data were collected from leaves and roots regarding their growth, fresh weight, sugar content, and starch content. The results revealed that temperature significantly affected leaves and roots parameters, fresh weight, and carbohydrate content of the plantlets. However, fertilizer rates alone showed no significant effects on the growth and carbohydrate content of plantlets. The highest leaf and root growth, root fresh weight, and leaf carbohydrate content were observed in plantlets subjected to 25°C. In addition, ‘KS Little Gem’ plants grown under 30°C had significantly inhibited growth and reduced carbohydrate content in both the leaves and roots.

This study aims to examine and measure the impact of capital structure on the profitability of companies in emerging markets. The research sample includes eighteen rubber companies listed on the Vietnam stock exchange from 2015–2019. After collecting the research data, it was imported into excel to calculate the criteria for the research model. By using Stata 16 software, the study selected a data processing model and evaluated the relevance of the regression analysis model. The research results show that the profitability of listed rubber companies in Vietnam (measured by return on equity (ROE) has a positive relationship with the debt-to-asset ratio but has a negative relationship with the long-term debt-to-asset ratio. The results also show a positive impact of firm size and revenue growth on profitability while liquidity and the ratio of tangible fixed assets to total assets do not affect significantly. These results are consistent with most of the previously published studies. However, in contrast to many previous studies, our study shows that the long-term debt-to-assets ratio has a negative effect on profitability while the debt-to-asset ratio has a positive effect. This is entirely consistent with the characteristics of long-term debt use in emerging markets.
