Abstract:
Background: Momordica charantia L., the common name for bitter gourd, frequently used as a vegetable and in traditional medicine to treat wounds, peptic ulcers, parasites, and worms. Regarding of finding alternative ways to cure nosocomial infection caused by multidrug-resistant bacteria, bitter gourd in combination with some antibiotics may be a practical choice to reduce the cost of therapy and be devoid of side effects from antibiotics. Objective: This study aimed to determine the antimicrobial, antibiofilm, and synergy effects of ethanol extract from bitter gourd in combination with conventional antibiotics, ampicillin, and oxytetracycline against some drug-resistant bacteria. Materials and methods: The antimicrobial activity was tested by broth microdilution, and the lowest concentration that inhibits the visible growth of each microorganism was recorded as MIC. A checkerboard microdilution assay was designed to test the synergistic effect of bitter gourd extract. A crystal violet staining assay was carried out to test antibiofilm activity Results: The bitter gourd extracted by ethanol revealed antibacterial activity with a MIC range of 1.25-80 mg/mL. Synergistic effects of bitter gourd extract with ampicillin and oxytetracycline were effective against P. mirabilis and drug-resistant P. aeruginosa growth by FICI at 0.141 and 0.63, respectively. The results found that bitter gourd exhibited antibiofilm activities against E. coli ATCC 25922, drugresistant P. aeruginosa, and Methicillin-Resistant Staphylococcus aureus (MRSA) at 2-4 hours after starting inoculum and the inhibitory efficacy values were 37.62%, 71.14%, and 69.87%, respectively. Conclusion: The ethanol extract from bitter gourd had antibacterial effect, synergy effect when mixed with ampicillin and oxytetracycline.

Abstract:
ABSTRACTBitter gourd (Momordica charantia L.) seeds is known to have efficacy in treating skin diseases, one of which is acne. This study aimed to determine the potency of antibacterial activity, minimum inhibitory concentration (MIC) and equality with comparator. The extraction process was carried out by maceration method using ethanol 96%, then fractionation was performed by using liquid-liquid extraction. The antibacterial activity of extract and fractions of bitter gourd seed against Propionibacterium acnes were done by agar diffusion method. The results showed that the extract and other fractions of bitter gourd seeds gave antibacterial activity against Propionibacterium acnes. The extract and three fractions of bitter gourd seeds inhibited the growth of Propionibacterium acnes at concentrations of 40%, 50% and 60%. The value of MIC of the extract was 30% with an 8,9 mm inhibit zone. At concentration of 40%, the fraction of ethyl acetate of bitter gourd seeds gave the highest activity in inhibiting Propionibacterium acnes compared to extract and other fractions. When it is compared with clindamycin as comparison, 1 mg of bitter gourd seed extract is equivalent to 0,80 μg clindamycin.

Abstract:
The present investigation was conducted to determine heterosis in 6 lines and 4 tester crosses of bitter gourd, where the six lines used were MC-84 (L1), S-17 (L2), JMC-21 (L3), NDBT-15(L4), VRBT-94 (L5) and Gy-1 (L6) and the four testers were VRBT-6-9 (T1), JMC-22 (T2), VRBT-89 (T3) and MC-56 (T4). Most of the crosses failed to manifest significant heterosis for many of the horticultural traits but traits, like vine length and fruit length showed positive significant heterosis, while, days to first appearance of female flower manifested negative significant heterosis in several crosses. Two crosses, namely, MC-84 x VRBT-6-9 and MC-84 x JMC-22 were identified to have potential in terms of yield, whereas two more crosses viz., S-17 x VRBT-6-9 and S-17 x JMC-22 were found superior in terms of powdery mildew resistance.

Abstract:
Fusarium wilt in bitter gourd caused by Fusarium oxysporum f. sp. momordicae (Fomo) is a severe plant disease that affects the world’s bitter gourd (Momordica charantia L.) cultivation. This study evaluated nine luffa hybrids for their performance as rootstocks with bitter gourd to control Fusarium oxysporum f. sp. luffae (Folu) isolate Fomh16 and Fomo isolate Fomo33. In the first evaluation, five hybrids (LF1, LF2, LF3, LF15, and LF16) exhibited resistance to the Fomh16 isolate and showed no symptoms. One hybrid, LF10, was resistant with a mean disease rating (MDR) of 0.9 at 28 days post-inoculation (dpi). Seven luff hybrids that displayed resistant and moderate resistance in the first evaluation were used as rootstocks with susceptible bitter gourd cultivars. Five rootstocks exhibited high resistance to Fomh16 and Fomo33 isolates, with their MDR ranging from 0.0 to 0.7. In addition, the findings revealed that both isolates could colonize the vascular bundle of all resistant luffa rootstocks at 28 dpi. However, the Fomo33 isolate could extend and colonize the vascular bundle of bitter gourd scion when grafted only with rootstock LF5 and LF11. The quantitative PCR results indicated that there were significant differences in the amount of the Fomo33 DNA between the bitter gourd grafted onto LF15 and LF16 rootstocks and the self-grafted plants; however, the pathogen cannot be detected in the bitter gourd scions grafted with resistant rootstocks. These findings provide valuable resistant sources that can be used as rootstocks to manage Fusarium wilt disease in bitter gourd.

碩士<br>國立屏東科技大學<br>農園生產系所<br>104<br>This is a study based on the comparison of using two different types of bitter gourd(Momordica charantia L.) 'Yua Hua' and 'Bi Hua' as the study material to observer the chemical and physical changes in different precooling temperature, maturity, packaging and 1-methylcyclopropene(1-MCP) treatment during the process of storage. By observing its storage life and shelf life changes, we can now choose the most appropriate storage conditions for transportation. 'Yua Hua' and 'Bi Hua' bitter gourd has significantly inhibiting of respiratory rate and ethylene production at 5℃. Not only light green fruit’s firmness and crispness will decrease rapidly than dark green, but also has longer shelf life and lower electrolyte leakage(EL), in contrast of total soluble solid(TSS), titratable acidity(TA) content and storage life has no significantly differences, therefore, we can reach to an conclusion that light green was better maturity. Quality has no significantly differences between 7 and 10℃ precooling temperature, but had higher ascorbic acid ascorbic acid at 7℃ precooling temperature. To reach to the goals of reducing chilling injury, decrease ascorbic acid, increasing of peroxidase, superoxide dismutase and catalase activity, bitter gourd has significantly extended storage life and shelf life by inhibiting of polyphenol oxidase activity and enhance the antioxidant capacity using packing polyethylene at 5℃. In spite of firmness, crispness, TSS content and EL has no significantly distinction, but could maintain the ascorbic acid content effectively, even has longer storage life and shelf life after 1-MCP treatment. When the bitter gourd return to 4℃, it has very short shelf life. But when the bitter gourd return to 10℃, it could extend the shelf life effectively. Therefore, we choice 10℃ for the return temperature, it could promoting commodity value effectively.

Abstract:
碩士<br>國立中興大學<br>園藝學系<br>93<br>Bitter gourd seeds have small cotyledons enclosed in a hard, thick seed coat. Which, limits germination to unacceptably low level. A number of pre-sowing treatments can increase germination by overcoming the limitations imposed by the seed coat. For all three varieties of bitter gourd seeds used in this study, germination at 30, 25and 20℃ were the best when seeds were clipped and soaked in running water for 12 hrs. Seeds immersed in 50oC water for 60 min exhibited significantly higher germination than seeds immersed at other temperatures and for different times. The germination of seeds treated with H2SO4 was the highest after 30 sec of immersion. However, germination decreased as immersion time increased beyond 30 sec. Germination was higher for clipped seeds immersed in 15% H2O2 for 25 min and for unclipped seeds imbibed with 1% H2O2 water. Priming seeds for 2 days with vermiculite No. 2 and NaOCl at a seeds: vermiculite # 2: 0.1% NaOCl ratio of 9:12:18, by weight produced the highest germination rate. The highest emergence rate was achieved with two different treatments of soaking clipped seeds in running water for 12 hr or immersing unclipped seeds in 50°C water for 1 hr. The conductivity of leachate from ‘Fen Ching’ and ‘Ching Pi’ bitter gourd seeds that were soaked prior to sowing was assayed during the first 12 hr of imbibition. The leachate from control seeds had the highest conductivity, while the leachate from seeds treated with H2SO4 exhibited the second highest conductivity. After imbibition for 12 hr, the lowest conductivity value was obtained from the leachate of seeds that soaked in running water or immersed in 50°C water. In addition, after soaking 24 hr, the leachate from the seeds in these two treatments contained significantly fewer phenolic compounds and free amino acids than the leachate from seeds that received other treatments. When seeds soaked in water for one hr, the soluble carbohydrates, phenolic compound and free amino acids from seeds soaked in 50°C water were significantly more than those in 25°C water. Seeds soaked in water for 12 hr contained significantly less water and more soluble carbohydrates, and had a significantly higher respiration rate than seeds soaked for 24 hr. The densest seeds were also the heaviest seeds and had the highest germination and shortest germination time (MDG). After-ripening significantly increased the germination and decreased the MDG of the densest seeds from completely yellow gourds. For seeds of a given density from half-yellow gourds, the germination of seeds after-ripened for 72 hr was significantly greater than the germination of seeds after-ripened for 24 hr. There were significantly more soluble carbohydrates in seeds from after-ripened, half-yellow gourds, than in seeds from untreated completely yellow gourds. Among seeds from half-yellow gourds, the soluble carbohydrates were highest in seeds from gourds after-ripened 72 hr, and starch content was highest in seeds from gourds after-ripened 24 hr. Seeds from fruit after-ripened 72 hr had the greatest emergence force. The effective and cheap pre-sowing methods were demonstrated in this research for enhancing seeds germination. Bitter gourd seed quality was enhanced by adequate fruit maturity, after ripening and seed density grading. The pre-sowing treatment that increased germination the most and was least expensive was seeds immersed in 50oC water for 60 min.

碩士<br>國立宜蘭大學<br>園藝學系碩士班<br>96<br>The purpose of this research probed into the physiological responses variations of grafted bitter gourd (Momordica charantia L.). The physiological responses observed in this study including the growth situation of the grafted seedling, the histology observations of grafted union acclimation process, measuring the fluorescence yield of the grafted seedling and investigating the content variation of peroxidase, catalase and proline. In this test, bitter gourd ‘high moon’ was used as scion and sponge gourd ‘Shuang yi’, pumpkin ‘Strong man’, ‘KY papaya type’ and ‘Mutual boom’ were used as stocks. The results showed that different scion and stock combinations made a big influence on growth of grafted bitter gourd plants. In all of the combinations, when bitter gourd ‘high moon’ was grafted on sponge gourd ‘Shuang yi’, the grafted plant reached the best growth condition. However, when bitter gourd ‘high moon’ was grafted on pumpkin ‘Mutual boom’, the grafted plant’s vigor was the worst. When bitter gourd ‘high moon' grafted on sponge gourd ‘Shuang yi' and pumpkin ‘Strong man', begin to produce callus on the 3th days after grafting. As on the 11th days after grafting, a large amount callus and new vascular tissue formed. On the 26th days after grafting, tissue of stock and scion mixed each other, furthermore the new vascular bundle tissue proliferated and parts of graft union were connected. The results of chlorophyll fluorescence parameter showed that the grafted seedling of bitter gourd ‘high moon' grafted on sponge gourd ‘Shuang yi' and pumpkin ‘Strong man' had obviously lower Fv/Fm than non-grafted seedlings from initial stage after grafting. Furthermore, the Fv'/Fm' value of grafted seedlings also lowered than that of non-grafted seedlings. Regarding to relationships between the graft union formation and enzymes contents (peroxidase, catalase and praline), the results indicated that while bitter gourd ‘high moon' grafted on sponge gourd ‘Shuang yi' and pumpkin ‘Strong man', the peroxidase activity reached the highest value on the 7th days after grafting. As catalase activity reached the highest value on the 7th days after grafting and the graft union had the most proline content on the 7th days after grafting. Besides, all the amount of the three substances dropped down immediately later. The growth of bitter gourd grafted seedlings could be precisely monitored by growth investigations, chlorophyll fluorescence measurements ,and enzymes activity varieties. The results of this research can be applied in the grafted seedling production process and significantly.

碩士<br>國立中興大學<br>農藝學系所<br>102<br>Bitter gourd is one of the Taiwan&apos;&apos;s major vegetable in summer, but it’s rarely studied on genetic characteristics. In order to realize the bitter gourd of agronomic traits, we used 55 inbred lines which were purified in TPSIPS as experience materials. Assay the inbred lines characteristics had significant for fruit length, fruit width, fruit circumference, fruit weight, fruit shape index, flesh thickness, flesh and marrow thickness. They showed diversity and variation with each inbred lines. In order to explore the fruit characteristics correlation co-efficiency, this results showed positively correlation for fruit length, fruit width, flesh thickness and flesh and pith thickness which can use reference. Further the Griffing (1956) and Hayman (1954) diallel cross theory, we explored the combination, heterosis and genetic components. Divided the bitter gourds by fruit shape index, selecting six inbred lines which were 343-2, 48-1, 298, 156-1, 350 and 42-2. We established the 36 crossing combinations (F1). General combining ability effects, only the dry weight is not significant. That means that the other characteristics are significant except additive gene action. The other characteristics are significant. In the early yield components, the first female flowering day and node had the least GCA with 298 inbred line which described the earliness characteristic. However, we can selection the yield traits according to female characters by node numbers at first female flowering and female flower number, but the fruit traits are also very important. The early yield and fruit traits showed that were not focused on the specific inbred line. Specific combining ability effect, at first female flowering nodes and days had the best with 343-2x350 and 343-2x156-1. Female flower number on the main stem from fifteenth to twenty-fifth had the highest with 298x350. On the fruit traits, the fruit length and weight had higher SCA with 298x42-2 and 156-1x48-1. We observed the better performance to be used breeding with those combination. On the gene effects of traits and genetic components, the plant traits were controlled by additive and dominant effects, and additive effects were larger than dominant effects for internode number and internodal length. The positive and negative dominance gene of traits expressed the asymmetric distribution, and controlling the dominance gene were 3-4 groups. Almost all plant traits were controlled by incremental gene. On the flower traits, all characteristics of additive effects were larger than dominant effect. Days to first male flower and ovary length do not have dominant effect, and the other flower traits were partial-dominance effect. On the fruit characteristics, the fruit length, fruit weight and fruit shape index had positive and negative dominance gene of traits express the asymmetric distribution. The addictive effects of all fruit traits were larger than dominant effect. Fruit length, fruit weight and fruit shape index were controlled by 4-5 and 3-4 groups dominance genes. All fruit traits were controlled by partial- dominance and incremental gene effect.

Abstract:
博士<br>國立屏東科技大學<br>農園生產系所<br>105<br>The fruit color and shape are important traits of bitter gourds (Momordica charantia L.) which are also the major targets of bitter gourd breeding projects. The objects of this study were to determine the genetic models of fruit color and shape in the bitter gourd. Six generations (P1, P2, F1, F2, BCP1 and BCP2) in the hybrid set ‘MS 41 × MS47’ were used to estimate the genetic effects via generation mean analysis (GMA), and determined the genetic mechanisms. The fruit color of the F1 population was green implying the green color was dominant over the white color. The fruit color of F2 population showed a continuous distribution from white to dark green indicating this traits was controlled by quantitative genes. Genetic analysis using the lightness, hue angle and the Royal Horticultural Society scoring system (RHS score) fitted the three parameters model, which Chi-square ( ) test estimates were 1.05 (P = 0.68233), 1.80 (P = 0.6157) and 1.59 (P = 0.6607), respectively. The results showed significant to highly significant additive and dominance effects. The value a and b of color difference, chroma and chlorophyll concentrations were not fitted three parameters genetic model which implied the epistasis was present. The GMA results of six parameters model revealed a significant additive effect on chlorophyll b concentration, and other fruit color related traits were nonsignificant in all parameters which was more complex genetic mechanism involved. The value b of color difference was affected by complementary epistasis, but the value a of color difference, chroma and chlorophyll concentrations were controlled by duplicate epistasis. Exclude chroma, the broad-sense heritability of all fruit color related traits were lower, between 0.226 and 0.510. About fruit shape related traits, the average single fruit weight of all hybrid and backcross generations were heavier than two parents that indicated the overdominance genetic effect. All fruit shape related traits of the F2 population showed continuous distributions that revealed the six traits were quantitative traits. Genetic analyses using all fruit shape related traits fitted the three parameters model that was additive-dominance genetic model and epistasis was absent. The Chi-square estimates were 5.606 (P = 0.132), 3.069 (P = 0.381), 1.319 (P = 0.725), 3.613 (P = 0.306), 2.036 (P = 0.565) and 4.741 (P = 0.38), respectively. Exclude the dominance effect of single fruit weight, all traits show significant or highly significant additive and dominance effects. The broad-sense heritability estimates were 0.788 and 0.878 for single fruit weight and top fruit width respectively, which were higher. The broad-sense heritability estimates were 0.578, 0.266 and 0.618 for fruit length, fruit width and fruit shape index, respectively, that were easier affected by environmental conditions. The correlation analyses of fruit color related traits showed highly significant effects between the RHS score, lightness, chlorophyll concentrations (|r| ≥ 0.724), which is a proper index of fruit color expression. The correlation analyses of fruit shape related traits showed highly significant effects between the fruit shape index, fruit length, fruit width and top fruit width, which estimates were 0.870, -0.839 and -0.792, respectively. The correlations analyses between fruit color and fruit shape got highly significant effects on chlorophyll concentrations, fruit length, fruit width and top fruit width. But correlation analyses were non-significant response between fruit color and fruit shape within F2 population. The fruit color and fruit shape related traits were controlled by additive, dominance and epistasis effects. The selection of breeding method is mostly depending on the value of broad-sense heritability of trait when it is conducted. The broad-sense heritability of fruit color related traits, fruit length, fruit width and fruit shape index were low at this study which suggested the use of recurrent selection. Traits with high broad-sense heritability, the single fruit weight and the top fruit width, will be recommended to conduct earlier generation selection which could promote the efficiency of selection.

Abstract:
Momordica charantia L., commonly known as bitter melon/gourd, is a slender tendril-climbing annual vine of the family Cucurbitaceae. Bitter melon grows in tropical areas, including parts of the Amazon, Asia, and the Caribbean, and is cultivated throughout South America. It is a common food of the tropics used in the treatment of many diseases and is also known for its potent hypoglycemic actions. A steroidal sapogenins known as charantin, insulin-like peptides, and alkaloids have been reported to have hypoglycemic or other actions of potential benefit in diabetes mellitus. The present chapter gives a comprehensive review of the tissue culture of Momordica charantia. There are two ways of regeneration, direct organogenesis and indirect organogenesis; both take place through the production of adventitious buds and somatic embryogenesis. The present review gives a complete in vitro regeneration protocol of M. charantia.

Abstract:
The aim of this study was to investigate the effects of zinc-free protein extract from bitter gourd fruit pulp on plasma glucose concentration and insulin responses in normal and STZ-induced diabetic rats. Furthermore, we investigated the direct effect of the MC protein extract on insulin and glucagons secretions from the perfused rat pancreas as well as glucose uptake in C2C12 rat myocytes and 3T3-L1 rat adipocytes. The protein from Thai bitter gourd (Momordica charantia) fruit pulp was extracted and studied for its hypoglycemic effect. Subcutaneous administration of the protein extract (5 and 10 mg/kg) significantly and markedly decreased plasma glucose concentrations in both normal and streptozotocin-induced diabetic rats in a dose-dependent manner. The onset of the protein extract-induced antihyperglycemia/hypoglycemia was observed at 4 and 6 h in diabetic and normal rats, respectively. This protein extract also raised plasma insulin concentrations by 2 fold 4 h following subcutaneous administration. In perfused rat pancreas, the protein extract (10 [M]g/ml) increased insulin secretion, but not glucagons secretion, which was apparent within 5 min of administration and was persistent during 30 min of administration. Furthermore, the protein extract enhanced glucose uptake into C2C12 myocytes and 3T3-L1 adipocytes. Thus, the M. charantia protein has both insulin secretagogue and insulin-like activities that could help explain its hypoglycemic effect in vivo.
