无叶的

The results showed that the overexpression of CBF1 could obviously improve cold tolerance of plant.Compared with non-transformed control plants,the transformed plants had a shorter and stronger stem,more leaves that were bottle-green and thicker,and a longer growth period.

结果表明：CBF1的组成型表达增强了冷敏感植物的抗寒性；在表型上使植株矮壮，叶片着生密集，叶色深绿，叶厚度增加；促进侧枝生长，延长营养生长期，推迟花期；对植株的结实性无明显影响。

Leaves simple, commonly opposite and decussate with one of a pair slightly smaller than other, rarely verticillate or alternate by abortion of one of a pair, usually 1-4(or 5) secondary veins on each side of midvein, originating at or near base and anastomosing apically, tertiary veins numerous, parallel, and connecting secondary veins and midvein but in Memecylon secondary veins pinnate and tertiary veins reticulate.

Leaves alternate, simple, pinnately veined, entire to irregularly serrate or lobed, rarely pinnatifid; stipules absent or rarely present.

In this paper the authors report on the biological characteristics of Al-sophila spinulosa Hook.

孢子—原叶体—孢子体的生活周期长，并且在丝状体、原叶体和幼孢子体阶段，无特殊结构去抵抗和忍耐一切不利环境因子的影响。3。

The pulley or fan bore shall be concentric and match the diameter of the rotor shaft.

风叶和皮轮必须无磨损或损坏，皮轮不应有碎屑，弯曲或其它瑕疵会干预驱动器皮轮的正常运转，皮轮和风叶孔应同心并与转子轴的直径相匹配。

Leaf sheaths glabrous or glabrescent; auricles and oral setae weakly developed; ligules scarcely exserted, apex concave, petioles slightly scabrous on both sides; blades 13.5–17.5 × 2.4–2.8 cm, oblong-lanceolate, glabrous adaxially, puberulous abaxially, transverse veinlets inconspicuous.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
