| Machilus paunoi Kanenira,a large evergreen tree belongs to the Lauraceae,Machilus Nees. Machilus paunoi Kanenira has very high economic value, its wood can be a material for construction and furniture. Leaves has very high medicinal value, it containing azulene compounds can extract essential oil. It is a good raw material powder is excellent ornamental, green trees, versatile and has broad development prospects. The species mainly in Anhui, Zhejiang, Hunan, Jiangxi, Fujian, Guangxi, Guangdong and other provinces. This paper shavings Yun Nan seedling growth of different provenances and rhythm and 11 were observed in response to the moon, and on the leaves of different provenances mention oil and gas chromatography- liquid joint analysis. The main findings are as follows:(1) Xing'an Guangxi and Fujian Yongchun growth height provenance highest, there is a significant difference from other provenances, followed Zhaoping and Jiangxi Suichuan provenances, height growth is the slowest provenance provenance Jiangxi Jeonnam, and other provenance differences reached a significant level. Difference fastest growing provenance and the slowest growth provenance height between 2.83 times. On average Xing'an Provenance diameter growth biggest difference with other provenances reached a significant level, followed by Fujian Yongchun provenance, Jiangxi Quannan provenance diameter growth was minimal, there are significant differences from other provenances.Shavings Run the seedling from different provenances nursery phase difference in mortality is quite obvious. Jiangxi, Zhejiang Jiande whole South mortality rate is high, up to 60%,while the provenances South Fujian Yongchun equality provenance mortality was 14%.(2) Machilus paunoi Kanenira shavings sources seedling growth is slow, is slow-growing type. Height and diameter growth of seedlings of various sources curve more consistent,did not show a common spring to autumn there are "slow- fast- slow" growth trend.Height growth began to accelerate in August, November-December growth slowed down,but rather to accelerate the growth of winter. Different height shavings Machilus paunoi Kanenira provenance growth vary. Chaling, Hunan Qiyang, Hunan Huitong three provenances into October after growing more slowly. Fujian Yongchun provenance in October is still in rapid growth phase, the provenance growth in October accounted for35.96% of the total growth of the month, the slow growth of other provenances. August--10 diameter growth slow and months, in October began to accelerate, winter still growing.Diameter growth rates of different provenances shavings Machilus paunoi Kanenira significantly different. In October and November, Yongchun, Fujian, Guangdong Lechang provenance grow the fastest, the biggest growth, and Jiande, Zhejiang, Anhui Huangshan provenance slowest growth, growth is also the smallest, after the end of November, various provenances are in the fast-growing period, which Xing'an, Yongchun, Fujian, Zhejiang Yueqing provenance of the fastest growing, growth is also the largest, other provenances are slow-growing.(3) According to November Observations, seedlings net photosynthetic rate Pn as the photon flux density increases, the trend is 10 kinds of sources basically the same. In0-500?mol. mol-2. Within the s-1 range, Pn value with the enhancement of the maximum rise PFD, after a little slow. Pn the maximum value for the Xing'an provenance, the smallest for Zhaoping provenance. Xing'an provenance of stomatal conductance(Gs) up. Zhaoping provenance of stomatal conductance(Gs) minimum. Fujian Yongchun Provenance intercellular CO2 concentration is consistently high. The intercellular CO2 concentration Zhaoping provenance has been low. Provenance Xing'an provenance of transpiration rate(Tr) has been higher than other provenances. Zhaoping provenance of transpiration rate(Tr)has been lower than other provenances. By analysis of variance, the differences in the physiological indexes of different provenances reached a significant level.(4) Machilus paunoi Kanenira leaf oil content of wood shavings to aliphatic and terpenoids as much, which aliphatic aldehydes has seven components: oct, nonanal, decanal,octadecene aldehyde, undecyl aldehyde, undecylenic aldehyde and dodecanal. Given that these aldehydes shavings Machilus paunoi Kanenira leaf oil is a good natural aldehyde fragrance, is a characteristic aroma. Different provenances shavings Machilus paunoi Kanenira leaf oil natural incense total aldehyde content there are significant differences, the most abundant species source Huitongru, leaf oil natural aldehydic relative content of92.9554%. Content from more to less provenances were, Hezhou, Renhua, Guangdong,Fujian Jian'ou, Jiande, Zhejiang, Jiangxi Chongyi, Fujian Nanping, Yangshan, Guangdong,Jiangxi Suichuan. Leaf oil natural fragrant aldehyde content is relatively minimal Jiangxi Wuyuan, the relative content of 43.8907%. |
