The difference between cedar and Korean pine

Cedar, also known as cedar, pagoda pine, cypress, Himalayan cedar, etc., is produced in western Asia, western Himalayas, Africa and the Mediterranean coast. Korean pine, also known as sea pine, fruit pine, Han pine, Korean pine, Korean pine and so on, are distributed in China, Japan, North Korea, South Korea, Russia and other places. Let's take a look at the difference between cedar and Korean pine.

The difference between the trunk of cedar and Korean pine

1. Cedar: the height of cedar is about 30 meters, and the breast diameter can reach 3 meters. Bark dark gray, split into irregular scales. The branches are spreading, slightly oblique or slightly drooping, the base persistent bud scales are inverted outward, the branchlets often droop, the annual branches are grayish yellow, densely tomentose, slightly powdery, and the second or third-year branches are gray, light brownish gray or dark gray.

2. Korean pine: the height of Korean pine can be up to 30 meters, and the DBH is 1 meter. The bark of the young tree is grayish brown, nearly smooth, the bark of the big tree is grayish brown or gray, split longitudinally into irregular rectangular scales, the upper part of the trunk is often bifurcated, the branches are nearly spreading, the crown is conical, the annual branches are densely yellowish brown or reddish brown pilose, winter buds light reddish brown, rectangular ovoid, apex pointed, microcoat resin, bud scales loosely arranged.

The difference between cedar and Korean pine leaves

1. Cedar: the leaves of cedar are radiated and stretched on the long branches, the leaves of the short branches are in clusters, needle-shaped, hard, light green or dark green, 2.5 cm long and 1 mm 1.5 mm wide, the upper part is wider, the apex is acute, the lower part is narrower, often triangular, the sparse ridge is obvious, there are 2-3 stomatal lines on the ventral side of the leaf, 4-6 on the back, and powdery when young.

2. Korean pine needles: Korean pine needles 5 needles a bunch, 6-12 cm long, thick, straight, dark green, margin serrulate, back usually without stomatal lines, ventral side with 6-8 light blue-gray stomatal lines. The cross section is nearly triangular and the subcutaneous layer is monolayer, but there is often a second subcutaneous layer with 1 to 3 or more to 15 cells wide between the two resin canals on the back, and 3 resin canals are mesophytic, located in three corners, and the leaf sheath is caducous.

The difference between cedar and Korean pine flowers

1. Cedar: the male flower of cedar is oblong or oval-shaped, 2-3 cm long and about 1 cm in diameter. Female cones ovoid, ca. 8 mm, ca. 5 mm in diam.

2. Korean pine: Korean pine male cones oval-cylindrical, red-yellow, 7-10 mm long, mostly concentrated in the lower part of new branches into spikes. Female cones green-brown, Terete-ovoid, erect, solitary or several collected on new branches near tip, with thick long pedicels.

The difference between cedar and Korean pine cones

1. Cedar: Cedar cones are light green before maturity, slightly powdery, reddish brown when ripe, ovoid or broadly oval, 7 cm long, 5 cm in diameter, blunt at the top and short stalked. Middle seed scale fan-shaped obtriangular, 2.5-4 cm long, 4-6 cm wide, upper broadly round, margin intrinsically curved, middle cuneate, lower auriculate, base clawed, dorsal scales densely tomentose. The bract scales are short and small, the seeds are subtriangular, the wings are broad, longer than the seeds, and the seeds are 2.2-3.7 cm long.

2. Korean pine: the cones of cedar are conical-ovoid, conical-oblong or ovate-rectangular, 9-14 cm long, sparse and longer, 6-8 cm in diameter and 1-1.5 cm in length. After maturity, the seed scales do not open, or slightly open to expose the seeds, but the seeds do not fall off. Seed scales rhomboid, seeds large, born in grooves in the ventral part of seed scales, wingless or slightly ridged at the top and upper sides, dark purple-brown or brown, Obovate-triangular, slightly flattened.
