Tamarind a sweet cultivated species, belonging to the type of the eve of the evergreen tree, currently in Thailand has been widely cultivated, is a traditional fruit, high prices are unsalable, generally by domestic and overseas scholars concern. Excessive introduction of foreign excellent germplasm resource, can fully and enhance the introduction of local plant resources gene pool, rich plant species of ecological diversity, genetic diversity and Germplasm and benign and beneficial to the ecological engineering construction of our country. The introduction and cultivation of three Thai sweet angle types for experimental data and on the phenology, growth stop indecent test and fruit character stop determined, and the use of AFLP molecular marker techniques, the genetic basic analysis, for the Thai sweet angle of introduction, evaluation, retention and genetic improvement of providing a scientific basis. Important conclusions are the following: (1) of sweet Thai tamarind in north frigid zone in dry hot valley region of phenological said can be divided for leaves sprout period, leaf expansion period and leaf stage, flower bud, flowering, full flowering stage and late flowering, fruit at the beginning of the pods, pods and mature three phenological period. The overall representation is common in early January to early April in late March to late May, leaves, bud bud. Buds formed in mid April to early, early May to mid June flower buds open, flowering in early May to mid October, harvest in late May the following year in early March, in next February to March early mature fruit. But the Thailand sweet angle between the 3 types of phonological period is not complete differences. (2) between the 3 types of Thailand sweet tamarind tree height, ground diameter and crown width were not significantly different between P ("0. 05). Note 3 species are similar in Yuanjiang River valley development hot region. (3) the nutrient components of 3 kinds of fruit in Thailand sweet angle are mainly in the total sugar and restored sugar, Vc content is also high, and rich in amino acids and a variety of mineral elements, must be a complete variety of amino acid. The fruit of a kind of "TJ3" must be reasonable, and the highest content of amino acids, with a rich nitrogen nutrient. Thai sweet tamarind fruit nutrient value is high, with very high processing application value and vast development prospects in fruit, beverage and food, is to develop a potential excellent capital plant with. (4) to take the AFLP marker technique, the genetic analysis of 3 kinds of sweet angle in Thailand, the introduction of the Thailand sweet angle gene capital diversity is in the medium level. Polymorphism markers percentage (PPL), indecent test useful and allele number (no), number of alleles (NE), Nei's gene diversity index, and Shannon diversity index (I), in the degree of species separation is 30. 72%, 1. 31, 1. 13, 0. 08 and 0. 13. (5) the results of AMOVA analysis showed that the differences of genetic differentiation between the 3 species of sweet angle in Thailand reached a very significant level (P 0. 01). Is the introduction of Thailand sweet angle between the cultivation of species, said a certain level of genetic differences, the introduction of the introduction of Thailand sweet angle capital of the basic characteristics of the general. Genetic differentiation coefficient of 3 species in Thailand sweet angle GST=0. 2895, there are 28 of the total genetic variation. 95% variation existed among species, and the genetic variation among individuals within species accounted for 71 of the total genetic variation. 05%. UPGMA approach to the clustering analysis results show that TJ1 and TJ3 first together for a class, and then together with TJ2, notes TJ1 and TJ3 genetic relationship between the closer, while TJ2 is far. 目录: |
