In the early december, the first bract primordium was formed in the axil scale at the cone base, then bract initiation had occurred in acropetal direction.

12月初，最初的苞片原基在雌球果原基的鳞片的叶腋处产生，之后其由基部向顶部连续发生。

At the end of February, the bract attained approximately their full size, and a pair of anatropous ovules were initiated on the adaxial surface at the base of the fertile ovuliferous scale.

2月底，苞片体积不再发生变化，珠鳞膨大端的基部的近轴面分化出2个倒生胚珠。

female flower subtended by large foliose, membranous bract to which pedicel is adnate;

雌花被大的叶状、膜质的、花梗贴生的苞片包围着；

bract blade palmately parted, broadly rhombic, 1--2 cm, abaxially sparsely puberulent, margin dissected lobed.

involucral bract blade 3-parted, obovate-rhombic, 1--3 cm, puberulent.

总苞片3深裂，倒卵形菱形，1-3厘米，被微柔毛。

fruit lens-shaped, attached to midrib of accrescent, membranous, reticulately veined floral subtending bract.

果透镜形，着生于增大，膜质，网状脉的花对着的苞片的中脉。

bract ovate; perianth shallowly cupular, puberulent, outer lobes broadly lanceolate, ca. 1. 8 mm, inner ones slightly shorter than outer;

Detection of Banana bract mosaic virus by real-time fluorescent RT-PCR

实时荧光RT-PCR检测香蕉苞片花叶病毒方法的建立

Shade had no effects on blooming date, but flower diameter, bract area had negative correlation significantly ( P < 0.05) with shade degree, and content of cyanidin had negative correlation very significantly ( P < 0.01) with shade degree.

遮荫对花期五明显影响，但花径、苞叶面积与遮荫度显著负相关（P＜0.05），苞叶花青素含量与遮荫度极显著负相关（P＜0.01）。

bracts numerous, overlapping, leathery, deciduous, apex deeply 3-lobed, each bract subtending 3 flowers.

Spadix rachis flat, margin with bract-like appendages; flowers small, monoecious, in 2 series on rachis, apetalous.

肉穗花序轴扁平, 边缘有苞片状附属物; 花小, 单性,雌雄同株, 呈2列排列于花序轴上, 无花被.

bract blade palmately parted, broadly rhombic, 1--2 cm, abaxially sparsely puberulent, margin dissected lobed.

掌状深裂的苞片，宽棱形，1-2厘米，被微柔毛的背面稀疏，边缘多裂浅裂的。

female flowers subtended by a small, entire bract, adnate to bracteoles and virtually submerged in wing complex;

雌花以一小，全缘苞片，贴生于小苞片和沉水的在翅复合体的实际上被包着；

The germination temperature for seeds with bract was 10~ 30 ℃;
