SUN Xiao-mei, ZHANG Shou-gong, QI Li-wang, WANG Jun-hui, LU Shou-fang, JIANG Ying-shu
2003, 16(5): 515-522.
Abstract:
Genetic parameters and selection index for pulpwood qualities were estimated for 12-year-old open-pollinated families of Larix kaepferi. Families differed significantly in holo-celouse,basic density,fiber length of early and late wood,wall/lumen of early and late wood,and also differed in 10 g·L-1 NaOH extract on 10% level. Heritabilities showed that all these wood qualities were strongly or moderately controlled by gene,which suggested that there were great potential to conduct the families' selection of pulpwood qualities. Correlations between basic density and wall/lumen of early and late wood,and 10 g·L-1 NaOH extract were positively high,and holo-celouse was negatively high,and it was independent with fiber length of early and late wood. Fiber length of late wood was positively correlated with fiber length of early wood,while negatively correlated with wall/lumen of early wood,and was independent with wall/lumen of late wood,holo-celouse and 10 g·L-1 NaOH extract. Holo-celouse was negatively correlated with wall/lumen of early wood,and was independent with wall/lumen of late wood. 10 g·L-1 NaOH extract were independent with holo-celouse,wall/lumen of early and late wood. According to the value of selection index of 15 families,the best families for pulpwood purpose were 249,340,346,217 and 364.

HU Yan-bo, HUI Gang-ying, QI Ji-zhong, AN Hui-jun, HAO Guang-ming
2003, 16(5): 523-530.
Abstract:
In this paper, three parameters were considered to be the suitable ones to describe stand spatial structure completely. The first one was mingling, which could be used to analyze the spatial distribution and isolation of species in the stands. The second one was neighborhood comparison, which could be used to characterize the size differentiation of trees. The third was neighborhood pattern, which could be used to describe the distribution of tree positions. The three parameters were used together in analyzing and describing spatial structure of Korean pine broad leaved forest. When using the distribution and the mean of mingling to analyze the spatial collocation of species in the stands, the authors could conclude that mingling intensity of most stands were middling and the most intensive. Tree position distribution was analyzed by using the mean and the distribution of neighborhood pattern.It was concluded that random distribution was the main spatial characteristics of most stand. After using neighborhood comparison and mingling to analyze spatial characteristic of main species, the authors could also consider that the combination of two parameters could be described the spatial characteristic of species clearly.

2003, 16(5): 540-547.
Abstract:
The factors of photosynthetic physiological ecology of Cryptocarya chinensis were measured with Li-6400 portable photosynthesis system under natural condition and control of irradiance,leaf temperature and CO2 concentration at tropical montane rain forest in Jianfengling,Hainan Island,during the dry season in 2001. The net photosynthesis Pn of leaves in the canopy did not vary much and it had the characteristics of low light saturation point (800 μmol·m-2 ·s-1),light compensation point (LCP was between 15 and 20 μmol·m-2 ·s-1) and the maximal photosynthetic rate (A max was less than 7 μmol CO2·m-2 ·s-1). The leaf photosynthesis could respond rapidly to the sunfleck but which lacked the adaptive responses when the high irradiance changed. The short-term response of Cryptocarya chinensis to enriched CO2 concentration could evidently increased the photosynthesis,however,the stomatic conductance and transpiration would be inhibited. Temperature response of photosynthesis showed that the net photosynthetic rate could be increased by 1. 6 times when air temperature was increased by 4 ℃ among the suitable growing temperatures,but beyond that photosynthesis would be inhibited. There was no evident correlativity between photosynthesis and leaf temperature,irradiance,CO2 concentration and leaf conductance under natural growing conditions,but conic correlativity exists when the growing conditions were controlled.

XIE Yu-rong, ZHOU Zhi-chun, JIN Guo-qing, CHEN Yue
2003, 16(5): 548-553.
Abstract:
Liquid culture at 3 phosphorus levels was conducted to illustrate P uptake and its kinetic parameters including Imax, Km and Cmin for five provenances of masson pine which showed different responses to phosphate fertilizer in the field trials.The results indicated that height growth and the amount of P uptake increased diversely with phosphorus raise for the provenances tested.However,the change patterns both in height growth and P uptake varied with provenances,among which Wuping of Fujian and Xinyi of Guangdong showed less sensitivity to phosphorus,compared with other three provenances.This result was similar to those from field trials.The kinetics experiments of phosphorus uptake by 0. 5 or 1-year-old seedlings drew the conclusion that,with the amelionation of phosphorus given,the Imax decreased while Km and Cmin increased in all provenances.Under low phosphorus stress,Xinyi of Guangdong and Wuping of Fujian had relatively smaller Km and Cmin,and higher Imax,especially for the latter which distributed in the southern region of Wuyi Mountain.

LIU Qiao-yun
2003, 16(5): 617-621.
Abstract:
Brush cutting and weeding were taken respectively in different bamboo groves which were harmed by leaf mites.After one-year study,the results showed that the damages and population density of leaf mites in weeded bamboo grove was higher than that in brush-cut bamboo grove.It was suggested that tending should hinge on local conditions.Bamboo grove should not be weeded,where brush was not luxuriant and the soil was porous.Brush cutting should be taken on August to September in bamboo grove where brush was luxuriant,but no weed.Study of letting off predatory mites to control harmful leaf mites showed that the control effect in bamboo grove with weeds was better than that in bamboo grove where weeds was eliminated or brush was cut.So complete reclaim and brush cutting should be prohibited in bamboo grove when predatory mites were used to control harmful leaf mites.
