from different areas and different species of pine needles from Jilin. Methods: HPLC and the Agilent ZORBAX SB- C18column( 4. 6 mm × 250 mm,5 μm) were adopted,with 0. 5% H3PO4( A)- acetonitrile( B) as the mobile phase with gradient elution( 0- 9 min,25% B→30% B; 9- ...
Pine needles, also known as pine straw, is an excellent mulch for flower beds. It’s light and doesn’t compact as it decomposes. It helps prevent weeds, evaporation, and erosion. Pine needles also insulate the ground, stabilizing the soil temperature. Best use: Best for flower or vegetable...

example, pine trees drop pine needles.And those needles add a lot of acid to the soil.The organic litter of another tree species might add less acid but more of something else.A lot of different types of trees in an area might mean more pedodiversity.Another cause? Gaps created when ...
In pine and spruce needles sampled in the late summer from trees grown in the polluted area, the DF induction curves assumed a multipeak shape characteristic of the later growth period. Therefore, the damage to the pigment complex of needles and primary photosynthetic processes, along with the ...
