Organic acid exudation from the roots of Chinese fir (Cunninghamia lanceolata) and Masson pine (Pinus massoniana) seedlings under low phosphorus stress was studied using the solution culture method.
      
The results revealed that organic acid exudation from the roots of Chinese fir and Masson pine seedlings under low phosphorus stress increased.
      
Compared with P3 (KH2PO4, 0.5 mmol/L), the average organic acid exudation from the root of Masson pine seedlings under P0 (KH2PO4, 0 mmol/L), P1 (KH2PO4, 0.03 mmol/L) and P2 (KH2PO4, 0.09 mmol/L) increased by 328.6%, 267.9% and 126.4% respectively.
      
Masson pine from Zhejiang Province in China had the highest organic acid exudation.
      
Under low phosphorus stress, the increase in organic acid exudation from the different provinces of Chinese fir and Masson pine varied.
      
Regressive models of the aboveground biomass for three conifers in subtropical China-slash pine (Pinus elliottii), Masson pine (P.
      
A power law equation with a single parameter (d) was proved to be better than the rest for Masson pine and Chinese fir, and a linear equation with parameter (d3) is better for slash pine.
      
With these equations, the aboveground biomass of Masson pine forest, slash pine forest and Chinese fir forest were estimated, in addition to the allocation of aboveground biomass.
      
The above-ground biomass of Masson pine forest, slash pine forest and Chinese fir forest was 83.6, 72.1 and 59 t/hm2 respectively, and the stem biomass was more than the foliage biomass and the branch biomass.
      
Although the habitat composition of the core area varied greatly for individuals, a large part of the habitats used were composed of confier and broadleaf mixed forests, masson pine forests, fir forests, and shrubs.
      
A study on the nutritive value of pollen from the Chinese Masson Pine (Pinus massoniana) and its effect on fecal characteristics
      
A digestion experiment with growing rats was conducted to study the effect of native and broken pollen of Chinese Masson Pine (Pinus massoniana) on fecal composition and digestibilities of dry matter, crude protein and crude ash.
      
Branching and growth of plantings in fifth year of a seedling seed orchard of Masson pine (Pinus massoniana Lamb.)
      
This result may have two main explanations: one is the growth rhyme in early ages of Masson pine, the other one is the complex paternal components to form the open-pollinated families.
      
Water status of bare-root seedlings of Chinese fir and Masson pine
      
The results showed that Masson pine had a lower osmotic potential (-2.07Mpa) at turgor loss point and at, full turgor (-1.29Mpa), compared with Chinese fir (-1.80Mpa and -1.08Mpa respectively).
      
The parameter Vp/V0 (63.27%) of Masson pine was higher than that of Chinese fir (58.03%).
      
This means that Masson pine has a stronger ability to tolerate desiccation, compared to Chinese fir according to analysis of above water relation parameters.
      
Water potentials of -1.60 Mpa and -1.70 Mpa were suggested to be critical values for Chinese fir and Masson pine respectively in successful reforestation.
      
Effects of water and heat stress treatments on chlorophyll fluorescence of Chinese fir (Cunninghamia lanceolata), Masson pine (Pinus massoniana) and western redcedar (Thuja plicata D.
