摘要
华西箭竹(Fargesia nitida)是大熊猫天然采食的主要竹种之一,由于开花习性独特,对其种子的研究报道还很少见。对华西箭竹种子的基本特征及不同温度下的萌发特性进行了研究。结果表明:华西箭竹种子长为(5.01±0.43)mm、宽(1.99±0.18)mm、厚(1.72±0.13)mm、千粒重(11.51±0.07)g;风干种子的化学组成:水分含量为(10.22±0.36)%、淀粉(74.52±0.57)%、粗蛋白(7.54±0.32)%、粗脂肪(3.71±0.17)%、可溶性糖(2.94±0.21)%、其他成分仅占(1.04±0.01)%。其种子萌发的适宜温度为20—25℃;低于20℃或高于25℃,种子的萌发率都会下降。
Fargesia nitida is one of the most important edible bamboos for Chinese giant panda. There were only a few reports about its seeds, because of its unique flowering characters. The characters of Fargesia nitida seeds and the effects of different temperatures in seed germination were studied in this paper. The results showed that: length ,width, thickness of seeds and 1000 -seed weight were (5.01 +0.43 )mm, (1.99 ±0.18 ) mm, ( 1.72 ± 0.13 ) mm and ( 11.51 ± 0.07 ) g respectively ; the contents of water, starch, protein, soluble sugar and the others of seeds were ( 10.22 ±0.36) %, (74.52 ±0.57) %, (7.54 ±0.32) %, (3.71 ±0.17) %, (2.94 ± 0.21 ) % and ( 1.04 ± 0.01 ) % respectively. The optimal temperature of seed germination was 20 ℃and 25 ℃. Lower or higher than 20 -25 ℃, was unfavorable for seed germination.
