Loblolly Pine Provenance Variation in Juvenile Wood Properties
Sun Haijing, Liu Zhaoxi
1997, 10(1): 46-53.
Abstract:
The wood basic density(BD), fiber length(FL) and latewood percentage(LP) of loblolly pine provenances were evaluated based on four 9-year-old provenance tests in Guangxi,Guangdong,Jiangxi and Zhejiang.The result showed that the provenance differ ence was significant for BD but not notable for FL and LP in every test location.The geographical variation patterns of wood properties of provenances were mainly two-way clinal ones influenced firstly by longitude and secondly by latitude.The BD of the western provenances were the highest,of the northern ones the next,and of south coast ones the lowest, the FL of the south coast provenances were the longest and of east coast ones the shortest, inland and northern provenances had the higher LP.The BD of loblolly pine were also different between test locations, decreasing from south to north.The provenance×test location effect for BD was small,most of the provenances displayed relatively higher stability.BD and LP were negatively correlated with the tree growth and yield traits,but FL was not correlated regularly with the tree growth traits,the three wood property traits also had complicated relationship with tree form traits.

Han Ninglin, Zhao Jinnian, Liu Zhaoxi, Yu Jianxin, Dong Yueqing, Zeng Wensheng
1997, 10(1): 70-75.
Abstract:
During 1991 to 1995,a series of high seed yield tests were conducted in the Slash Pine Orchard in Changle Forest Farm.After knowing the cause for lower seed yield, the density was reduced from 270 to 135 tree/ha.Several clones,such as Ⅱ-33, Ⅵ-60 which could produce more seeds than the others were found.These clones possess the characteristie of earlier flowering.It means their conescould be developed normally in a lower temperature condition.Fertilizing,epecially P,K could increase seed production with a rate over 100%, the Zn and P could double increase the rate of seed from the cone.A slight beat on the hark of tree trunk called "kei-jia" in Chinese could promote flowering and increase cone production over 30.0%.Three years after the treatment,the tree trunk is still normal,it means the slight beat at the bark could be used in the production.It is useful to pollen or spray MG-powder,a special powder for seed production, during flowering period,which could increase the seeds from the cone with a rate of 47.6%,51.2%, respectively.The cone pests should be controlled.Application of all these methods made the rate of the seed out of cone increase from 0.59% to 2.05%, the seed yield increased from lower 3kg/hm2 in 1992 to over 18kg/hm2 in 1995 in the whole orchard with on area of 20hm2.

Su Mengyun, Liu Zhaoxi, Zhou Guozhang
1997, 10(1): 90-92.
Abstract:
Through analysing the sucrose, total soluble sugar and starch contents in leaves of two types of seedlings with different growing rates (fast growing and slow growing) of loblolly pine (Pinus taeda L.) and slash pine (Pinus ellinttii Engelm),it was found that there was an obvious difference in sucrose contents between the two patterns of seedlings of loblolly and slash pine.The sucrose contents in leaves of the fast growing seedlings of loblolly and slash pine increased by 8.6%~26.2% and 114.1%, respectively, as compared with those of the slow growing seedlings.The sucrose contents in leaves of superior provenance seedlings of loblolly and of superior family seedlings of slash pine were 55.1% ~ 93.3% and 87.5%~168.4% higher than that of control provenance and family respectively.Results showed that there was a relationship between the sucrose contents in seedlings of loblolly and slash pine, and their growth potential.

Cui Yongzhong, Chen Yude, Zheng Derong
1997, 10(1): 93-95.
Abstract:
One way for reproducing Phyllanthus emblica is adopting its favourable seedlings, the other is through grafting to improve the qualities of its wild varieties.Whether using ideal cultivated or wild graftings, the rooting rate is not high by way of propagation by cuttings.The issue remains to be studied further.
Preliminary study on Effect of INA Bacteria ot Kill Larva of Anoplophora glabripennis through Freezing-induction
Sun Fuzai, Xing Wei, Zhang Yongxiang, Gao Ruitong
1997, 10(1): 96-99.
Abstract:
The influence of INA bacteria to the freezing temperature of larva of Anoplophora glabripennis, which caused serious damage in forest production in recent year, inoculated by spraying or feeding was tested.It was showed that the supercooling point of the larva could be raised by the INA bacteria inoculated by two methods,the mean freezing temperature of insects sprayed by INA bacteria was 7.04℃ higher than that of the control,and the mean freezing temperature of insects fed by INA bacteria was 5.62℃ higher than that of the control,the temperature of the former was higher than the later.All these freezing temperature reduced later on.The results proved that INA bacteria could be used as a freezing- induced insecticide which reduces the cold-hardiness of the insect, prolongs the duration of freezing of the insect, destroys the cell tissue of the insects.It also provided the evidence of using the INA bacteria in pest control in way of reducing the population of overwintering larvae.

Li Yanqun
1997, 10(1): 108-110.
Abstract:
The bleeding on the living Phyllostachys pubescens was tested.No significant correlations were found between bleeding amount and DBH of Ph.pubescens.There were no significant changes of bleeding amount on 5 to 8 years old Ph.pubescens.No bleeding was found 24 hours later after being wounded.The bleeding amount significantly changed with site conditions, area of wound and cutting time.The bleeding amount was larger when Ph.pubescens located on the moist and shady area.The larger the area of wound, the more bleeding.Under the sunshine, no bleeding occured at the wound.However, it bled if the wound was made in evening or later.
