Ho VT, Ngo QNg. 2017. Short Communication: Using RAPD technique to evaluate genetic diversity of longan (Dimocarpus longan) population in Vietnam. Biodiversitas 18: xxxx. Longan (Dimocarpus longan L.) is an important fruit plant in Vietnam where several cultivars and landraces are being cultivated. Presently, the identification of longan cultivars and landraces is mainly based on personal experience relying on morphological traits leading the difficulty of genetic conservation and longan breeding. In this study, genetic richness and relativeness of 36 longan accessions collected from different provinces in Vietnam were evaluated by using 30 Random Amplified Polymorphic DNA (RAPD) primers. Our results reveal that there is the large variation of genetic background of studied longan accessions with separate groups in the obtained dendrogram. We also identified the combination of different RAPD markers could help to identify 15 longan genotypes. The results from this project could provide valuable information which is necessary for classifying, identifying plant origins, breeding and conserving programs of longan in Vietnam.

Abstract:

Abstract Plant Growth Regulator Sprays and Girdling: Potential Horticultural Techniques to Increase Fruit Retention and Yield of Longan (Dimocarpus longan Lour.) Trees in California Leila Graves June 2009 The longan is a subtropical fruit tree whose popularity is growing quickly among American consumers, and thus, could become a lucrative niche market for California growers. Trees planted as part of an initial variety trial conducted in commercial California orchards are beginning to bear fruit. However, fruit retention and yields are low due to excessive abscission during early fruit set. Horticultural techniques, such as plant growth regulator (PGR) sprays and girdling, often increase fruit retention and yield of fruit tree crops, though effects are typically dependent on treatment timing and PGR concentration. The objective of this study was to identify PGR and girdling techniques that result in increased longan fruit retention. The experiment was conducted in a commercial orchard using a randomized complete block design with whole-tree experimental units and five replications per treatment. Treatments included foliar applications of two synthetic auxins, 1-naphthaleneacetic acid (NAA) at 20, 60, or 100 ppm or 2,4-dichlorophenoxyacetic acid (2,4-D) at 5, 25, or 45 ppm, each applied during early or late fruit set. Girdling was also conducted at early or late fruit set, for a total of 15 treatments, including an untreated control. Factors examined at harvest included fruit number and mass per inflorescence and individual fruit mass and diameter. During the on-crop year, a significant increase in the number and mass of fruit per inflorescence was observed in response to 25 ppm 2,4-D applied at late fruit set, as compared to the control. Despite this increase in fruit number, 25 ppm 2,4-D applied at late fruit set did not result in decreased diameter and mass of individual fruit. Late fruit set applications of 25 ppm 2,4-D appear to mitigate the effects of alternate bearing in the off-crop year. Fruit abscission during early and/or late fruit set decreased in response to 5 ppm 2,4-D at early fruit set, 25 or 45 ppm 2,4-D at early or late fruit set, or 100 ppm NAA at early fruit set. Fruit loss occurred as a result of Santa Ana winds during both growing seasons. Neither leaf nor fruit nutrient concentrations of treated trees were significantly different from that of untreated controls. Results indicate that properly-timed PGR applications have the potential to be used commercially to increase yield and profit to longan growers in California.

In this study, for high variation of fruit in longan, 'Fenke' of main cultivar in Taiwan, 'Shuigong' of big fruit, 'Wuyueyan' and 'Hongkezaosheng' of early cultivar, 'Qingke' and 'Hongke' of small seed, and 'Congzai' and abroad-introduced cultivar 'Bai Dum' and 'Sak Ip' were investigated. The result showed that change of fruit weight or volume in 'Bai Dum' was a sigmoid curve. The fruit of 'Bai Dum' developed slowly from the day of pistillate blooming to 49 days after pistillate blooming (DAPB), and after that was fast development of fruit. The intersection of slow development to fast development of fruit was 45.5 ± 4.2 DAPB for nine cultivars of longan. Fruits of 'Sak Ip', 'Fenke', 'Qingke', 'Congzai', 'Shuigong', 'Hongkezaosheng', 'Hongke' and 'Wuyueyan' were developed slowly at first, then developed fast at that intersection of fruit development. While total soluble solids in aril reached the maximum for each cultivar of longan, the fruit weight and volume of the highest cultivar 'Shuigong' (132 DAPB) were 14.1 ± 1.4 g and 12.8 ± 1.4 cm3, respectively. The fruit densities of nine cultivars were affected by density-changed peel, aril and seed. Fruit shape indexes of all were decreased with fruit development, and the fruit shape index was about 1 when the total soluble solids in aril reached the maximum. The fruit shape indexes of 'Hongke' and 'Wuyueyan' were 1.00 ± 0.02 (120 DAPB) and 1.00 ± 0.04 (141 DAPB), respectively. And, the decreased total soluble solids of aril at early development might be affected by embryo and seed abortion in these cultivars. Finally, 'Fenke', 'Qingke', and 'Congzai' could be harvested while percentage of aril weight reached 53.1 %; and 'Bai Dum', 'Sak Ip', 'Shuigong', 'Hongkezaosheng', 'Hongke' and 'Wuyueyan' could be harvested while percentage of aril weight reached 60.3 %.

Potassium chlorate (KClO3) is important for longan off-season production in many countries but its mechanism on floral induction is still unclear. Thus, the effect of KClO3 on off-season flowering in ̀Fenker ́ longan was investigated in this study. Result was shown that percentage of budbreak and flowering of KClO3 treated plants in normal season of winter were less effective and inconsistent. The percentage of budbreak in KClO3 treated tree was not significant difference but KClO3 treatment delayed flowering around 9-10 days compared to untreated tree. Flowering percentage after KClO3 treatment were 60% for trees (80 g/tree) and 100% for potted plants (2 g/plant). The inconsistent flowering and late flowering were may be because of low temperature (below 20 ̊C) which was not suitable for floral induction by KClO3 treatment. Percentage of budbreak in KClO3 treated potted plants in off-season of summer (100%) and autumn (70%) which were higher than in untreated plants (70% in summer; 6.2% in autumn). The KClO3 treatment induced off-season flowering in both season, flowering percentages in summer and autumn were 72.5 % and 68.1 % in new shoots, respectively as compared to no flowering untreated plant. In addition, it was found that girdling inhibited vegetative flush and improved percentage of leafless panicle after KClO3 treatment. Supplying 67% of water requirement (low irrigation) showed the negative effect including the reduction of budbreak percentage and tended to reduce flowering percentage after KClO3 treatment in autumn. Well water irrigation is necessary for floral induction by KClO3 treatment in autumn. Total soluble sugar in shoots of KClO3 treated plant was significantly increased on 21st day after treatment in summer and autumn, while, root viability was decreased. The high correlation coefficient was observed between total soluble sugar content in shoots during floral induction period and flowering percentage in both summer (0.91**) and autumn (0.579*). It is considered that the increase of total soluble sugar in shoots and the reduction of root viability enhance the floral induction.

Atherosclerosis is the major cause of cardiovascular disease, and the oxidation of low density lipoprotein (LDL) cholesterol is the important step to initiate atherosclerosis. Antioxidants can increase the resistance against oxidative damage, so the supplementation of food with antioxidants may help prevent the incidence of atherosclerosis. Previous year study in our laboratory has shown that Longan (Dimocarpus longan Lour.) flower had good antioxidative activity. Therefore, the objective of this study is to conduct antioxidant activity-guided separation and purification of Longan flower by the major antioxidative assay, the inhibition of Cu2+-induced human LDL oxidation, and to identify the effective compounds. After liquid-liquid partition of Longan flower methanol extract with n-hexane, ethyl acetate, n-butanol and water, the ethyl acetate fraction showed the best antioxidant activity. The EC50 value of the ethyl acetate fraction in scavenging DPPH radicals was 5.28 ± 1.14 μg/mL, and its effect of delaying LDL oxidation is 1.14 times better than Trolox at the same concentration level (1μg/mL). Besides, the ethyl acetate fraction had the highest contents of total polyphenol (701.7 ± 29.3 mg gallic acid /g dry weight of sample) and flavonoid (213.7 ± 14.8 mg catechin equivalent /g dry weight of sample). Silica gel chromatography was employed to fractionate the ethyl acetate fraction of Longan flower methanol extract, and twenty sub-fractions were obtained. DPPH assay showed that the sub-fractions with medium to high polarity had better antioxidative activities. Result of ORAC assay revealed that F8~11 were the more effective sub-fractions and F9 (eluted by ethyl acetate/n-hexane=60/40, v/v) gave the highest ORAC value (25.07 ± 4.08 Trolox equivalent). As for the effect of Cu2+-induced oxidation of human LDL, F8~11 also showed better effect in delaying LDL oxidation. Among them, F10 (eluted by ethyl acetate/n-hexane=70/30, v/v), which had superior effect, was 1.72 times better than Trolox at the same concentration level (1μg/mL). Further analysis of these sub-fractions showed that F9 contained the hightest amounts of total polyphenol (970.4 ± 11.2 mg gallic acid /g dry weight of sample) and total flavonoid (732.9 ± 19.0 mg catechin /g dry weight of sample). The trends of total flavonoid contents and the antioxidative activities of the four sub-fractions (F8~11) were similar, we therefore supposed that the antioxidative activity of Longan flower was highly related to its total flavonoid content or composition. There was only one major compound present in F9 by HPLC analysis and it was identified as (-)-epicatechin by spectrometric analysis of IR, MS, UV-Vis, 1H-NMR, 13C-NMR and 2D-NMR. After separating F10 by Sephadex LH-20, two major components were identified as (-)-epicatechin and proanthocyanidin A2. Both of them had superior effect in delaying LDL oxidation, and the lag time of each compound was 1.95 ( (-)-epicatechin ) and 2.04 ( proanthocyanidin A2 ) times better than Trolox at the same concentration level (0.5μg/mL). The contents of (-)-epicatechin and proanthocyanidin A2 in Longan flower were quantified by HPLC to be 5.58 and 1.70 mg/g dry weight, respectively. This study showed that Longan flower contained components with excellent activity, it thus has good potential to be developed as a functional food.
