Melon fruits are a year-old plant in the family Cucurbitae and are the most cultivated fruit in tropical countries. Melon flesh is an important source of anti-cancer, antioxidant effects, attracting attention as a functional food. We investigated the morphological properties, β-carotene content, and cucumisin activity of seeds of 58 melon genetic resources. Melon resources have shown various morphological properties. Melons grouped by morphological properties were the five groups. β-carotene content varied between 82.34 mg/kg, 86.75 mg/kg, 25.56 mg/kg, 86.25 mg/kg, and 54.65 mg/kg. Between β-carotene, cucumisin activity and other quantitative fruit morphological properties, the color of the pulp and the firmness of the pulp had a significant amount of correlation between the β-carotene content. However, cucumisin activity and β-carotene content had significant negative correlation, and the color of the fruit and shape of the fruit had significant negative correlation with β-carotene content and activity of cucumisin. Our study vindicated that high diversity in melon morphological characters of genetic sources that provide beneficial baseline data for the future and in the activity of β-carotene and cucumisin, and these results could predict indicators of β-carotene content by the length of leaf, the width of fruit, the length of joint, and the length of seed, and collectively the morphological properties of melons could help predict indicators of β-carotene content and help develop functional sarcoma and farmhouse cultivation.

Environmental conditions can influence the morphology of local biota through phenotypic plasticity or local adaptation. Macroalgal morphologies are often associated with wave-exposure conditions. We investigated the relationship between morphology and wave exposure in two common endemic subtidal macroalgae, Carpophyllum angustifolium and C. maschalocarpum, from the East Cape of New Zealand. Morphological comparisons were made between individuals from two sites and four different wave-exposure zones, as defined by fetch and barnacle composition. Of the seven morphological traits measured in C. angustifolium, only total length varied, and individuals were longer in more wave-exposed environments between the two exposure zones where the species were found. In contrast, total length, stipe thickness and vesicle presence all varied significantly between exposure zones in C. maschalocarpum. C. maschalocarpum specimens were shorter with thinner stipes, and fewer individuals had vesicles in the more wave-exposed zones. Morphological traits of both species also varied between sites, suggesting that other influences are important for determining species morphology. Further study is needed to investigate the role of phenotypic plasticity and genetic variability for driving morphological variation in C. angustifolium and C. maschalocarpum.

This study investigates morphologically complex nouns in Korean through a series of priming studies. Two experiments examined whether morphological affixes on Korean nouns were decomposed or processed as a whole. Two types of morphological affixes were examined: morpho-syntactic case markers and the plural marker '-tul'. Results showed that priming occurred for the plural marker with SOAs of 80 ms and 160 ms, but no priming occurred for the morpho-syntactic case markers. These results suggest that the morphological processing for these two types of affixes differ. We argue that Korean nouns with the plural suffix are decomposed into the stem and affix, supporting the Decomposition Model (Pinker & Ullman, 2002). We suggest that while plural markers are truly morphological affixes, case markers in Korean are morpho-syntactic, and thus presuppose the existence of other syntactic elements, such as the matrix verb, hence the lack of priming effects.

Fifty-nine Korean soybean (Glycine max L. Merr.) landrace accessions were tested for genotype fingerprinting, differentiation and association between morphological traits and SSR profile. Using 8 SSR loci, 59 varieties were divided into 55 groups, and only 4 pairs of varieties were not uniquely identified. The resolving power of SSR for soybean genotyping was much higher than that of the morphological traits that were studied. Identification efficiency also differed among SSR loci. Those loci with higher numbers of alleles distinguished varieties more effectively. Genetic differentiation values of the soybean landraces varied from 0.57 to 0.82 with a mean of 0.68. The number of alleles detected by the 8 loci ranged from 3 to 8. and the effective number of alleles ranged from 2.3 to 5.1. In a study of the association of SSR alleles with morphological traits, some alleles seemed to be related with some specific morphological traits. Comparison of two kinds of dendrograms which were derived from SSR markers and quantitative traits indicated that the dendrograms were not consistent. Considering the correlation between single SSR locus and qualitative traits governed by major genes, the data suggest that alleles of microsatellite loci be more closely related to some traits determined by major genes than those determined by minor genes.

Most previous studies on dinoflagellates in Korean coastal areas were conducted without morphological descriptions and illustrations of the observed dinoflagellates. This indicates that the species and diversity of dinoflagellates may have been respectively misidentified and underestimated in the past, probably due to cell shrinkage, distortion and loss caused by sample fixation. This study provides information on the morphological observations of four dinoflagellate orders (Prorocentrales, Dinophysiales, Gonyaulacales and Gymnodiniales) from Jangmok Harbour in Jinhae Bay, Korea. The unfixed samples were collected weekly from December 2013 to February 2015. A total of 13 genera and 30 species were identified using light and scanning electron microscopy, although some samples were not clarified at the species level. Harmful dinoflagellates, Prorocentrum donghaiense, Tripos furca, Alexandrium affine, A. fundyense, Akashiwo sanguinea and Cochlodinium polykrikoides, were identified based on the morphological observations. The results also reflect the occurrence and identification of dinoflagellates that had not been previously recorded in Jangmok Harbour.

This paper presents the development of a morphological processor for the Mongolian language, based on the two-level morphological model which was introduced by Koskenniemi. The aim of the study is to provide Mongolian syntactic parsers with more effective information on word structure of Mongolian words. First hand written rules that are the core of this model are compiled into finite-state transducers by a rule tool. Output of the compiler was edited to clarity by hand whenever necessary. The rules file and lexicon presented in the paper describe the morphology of Mongolian nouns, adjectives and verbs. Although the rules illustrated are not sufficient for accounting all the processes of Mongolian lexical phonology, other necessary rules can be easily added when new words are supplemented to the lexicon file. The theoretical consideration of the paper is concluded in representation of the morphological phenomena of Mongolian by the general, language-independent framework of the two-level morphological model.
