ABSTRACT: To study the difference of the quantitative multistate character of infructescence of Amomum tsao-ko from five populations, and the correlations between the quantitative multistate character and altitude, longitude and latitude.
By observing and analyzing the quantitative multistate character of infructescence of Amomum tsao-ko from five populations.
There is highly significant difference among the number of flowerlets each inflorescence from five populations. The higher the altitude, the less the number of flowerlets each inflorescence; and the higher the longitude is, the more the number of flowerlets each inflorescence. The temperature and the humidity of the circumstance affects the number of flowerlets each inflorescence. Lower temperature, higher diurnal variation of temperature, and higher diurnal variation of relative humidity causes less number of flowerlets each inflorescence. There is significantly negative correlation between the number of flowerlets each inflorescence and the maturing rate of infructescence. The difference of the maturing rate of infructescence from five populations don't approach significant level. The difference of the maturing rate of infructescence approaches significant level by multiple comparisons between Magnan population and Baoshan population, Gongshan population and Xichou population. There is not significant correlation between the maturing rate of infructescence and the altitude, the longitude and the latitude.
The factors of the circumstance affects the number of flowerlets each inflorescence. The climate by the change of the altitude affects the number of flowerlets each inflorescence highly significantly. Selecting the fine genetic resources of Amomum tsao-ko for high yielding, the number of flowerlets of inflorescence is not better character. Maybe the difference of the maturing rate of inflorescence is mainly caused by different genetic resources. Analyzing the difference of genetic regenetic resources of Amomum tsao-ko.

ABSTRACT: To study the anatomical structure of endangered alpine medical plant Neopicrorhiza scrophulariiflora and the high altitude adaptability.
The leaf epidermis character as well as section structure of leaf, aerial stem and rhizome were observed by light microscopical technique.
The leaf surface of Neopicrorhiza scrophulariiflora was covered with two kinds of glandular hair, and the stommata was anomocytic type. Moreover, the leaf was isolateral and differed from most of alpine plant. The aerial stem had well-developed mechanical tissue. The rhizome was distributed by well-developed cork layers and collenchyma. Large numbers of aerenchymas distributed widely in leaf, aerial stem and rhizome.
There existed characteristic traits in Neopicrorhiza scrophulariiflora that adapted the alpine environment, however, there still had some particular character different from other alpine plant. Thus, the adaptive style of alpine plant to high altitude environment was diversity.

ABSTRACT: To explore the regulation of the growth of fruit of Amomum tsaoko and the factors influencing the weight of fruit.
To compare and analyze the quantitative multistate character of fruit and seed of Amomum tsaoko.
The quantitative multistate character of fruit and seed of Amomum tsaoko in populations and between populations were abundant. There was positive relativity between the rate of fertilization of ovule and the rate of fructify and this indicated the different heredity character among plants. The weight of fruit was mainly decided by the weight of seed regiment, The more the seed quantity, the larger the weight of seed regiment, and the larger the weight of fruit, then the higher the yield. The variety of the weight of fruit and the quantity of seed presented peak form along with the proper order of fruit growth in inflorescence but had no relativity.
The abundant quantitative multistate character of fruit and seed of Amomum tsaoko provide the abundant materials for selecting good varieties. For high yield we should not only choose plants with high rate of fructify and high rate of fertilization of ovule the, but also pay attention to the influence of pollination to yield.
