The artificial flower doctrine that with German botanist Engele is a delegate thinks the flower of angiosperm and gymnospermous ball flower agree completely, every stamen and carpel, be equivalent to a male flower that degrades extremely and female flower respectively, consequently tentative idea angiosperm is to come from child plant hemp is yellow kind yellow Ephedra Campylopoda of curved handle hemp, following plan institute are shown, in this tentative idea, the bud of male flower piece turn into perianth, the bud of female flower piece turn into carpel, the small bud of every male flower piece after disappearing, remain a stamen only, female flower small bud piece ovule is remained only after disappearing, ministry of foundations of move unripe Yu Zi.

以德国植物学家恩格勒为代表的假花学说认为被子植物的花和裸子植物的球花完全一致，每个雄蕊和心皮，分别相当于1个极端退化的雄花和雌花，因而设想被子植物是来自棵子植物麻黄类的弯柄麻黄Ephedra campylopoda，如下图所示，在这个设想里，雄花的苞片变为花被，雌花的苞片变为心皮，每个雄花的小苞片消失后，只剩下一个雄蕊，雌花小苞片消失后只剩下胚珠，着生于子房基部。

The amount of flower strobilus was significantly different in the different layers of canopy.

雌球花主要集中在上、中层，下层极少；雄球花则主要集中在中、下层。

The results indicated that the amount of female and male flower strobilus, either within a family or between families, was significantly different, and the amount of female flower strobilus was also different from that of male.

结果表明：家系间与家系内球花量差异显著。马尾松球花花量在不同冠层的分布呈现显著差异。

The amount of female and male flowers strobilus from 12 families was investigated in Baisha seedling seed orchard of masson's pine from Shanghang County, Fujian Province.

观测了福建省上杭县白沙林场马尾松实生种子园的21个家系花量，分析了家系内与家系间雌雄球花量、各家系雌雄球花量在不同冠层和方位的分布。

Reduction of ovule number as a tendency of speciation in the genus is substantiated by the occurrence of tri_ovulate cones coupled with comprehensive characters of the genus. The metamorphic patterns as well as the leaf nature of the outer envelope indicate that female cones of Ephedra are compound while the female reproductive units of the ovulate cone have been reduced from secondary reproductive shoots similar to those of cordaites by phylogenetic transformation, fusion and reduction. Each fertile bract together with its axillary female reproductive unit composed the Bract Scale and Seed Scale Complex of Ephedra .

基于返祖性畸形三胚珠球花的出现及其他形态特征，认为麻黄属胚珠数目减少是该属内物种特化的一个趋势；利用雌球花发育的畸形现象及外珠被的形态学本质提出麻黄属的雌球果为复轴性构造，雌性生殖单位是由类似于科达类的次级生殖枝构造经系统发育变态、融合、简化成现存的生胚珠构造式样，每一可育苞片及其腋内雌性生殖单位共同组成了麻黄属的苞鳞_种鳞复合体。

Tibet still produces Huang Xinqiu to spend newspaper spring P.erythrocarpa, bhutan also is produced; The distinction that spends newspaper spring with Bai Xinqiu is corollaceous blue purple, laryngeal yellow, distributinging altitude is inferior (1500-3000m).

西藏还产黄心球花报春P.erythrocarpa，不丹也产；与白心球花报春的区别为花冠蓝紫色，喉部黄色，分布海拔较低(1500-3000m)。

Based on the investigation and analysis of the Cupressus funebris seed orchard at Laoshan Island in the Qiandao Lake, Zhejiang province, the ecological characteristics of the male cone, female cone and pollen have been studied.

本文以浙江省千岛湖姥山林场柏木种子园为对象，对柏木球花及花粉的生态学特性进行了研究结果表明，柏木的雌雄球花在树冠中呈成层分布；降雨时，雄球花对花粉具有保护功能；柏木花粉体积小，重量轻，花粉量大，花粉的散发受气温、风力、相对湿度和气压的综合影响，其中气温是主导因子，风左右着花粉的传播，降雨加速花粉的沉降。

Dioecious monoecious, reproductive structures axillary, solitary. Pollen cones pedicellate, globose, with overlapping bracts at base; microsporophylls 6-14, shield-shaped, each with 4-9 radially arranged pollen sacs. Seed-bearing structures subsessile, with several overlapping bracts basically. Ovule erected, entrusted with disc-like embryophore. After fertilization, embryophore developed into fleshy, cup-like and red aril.

雌雄异株，球花单生于叶腋，有短柄；雄球花圆球形，基部覆瓦状排列的苞片，雄蕊6-14枚，盾状，花药4-9丝，辐射状排列；雌球花几乎无柄，基部有多数覆瓦状排列的苞片，胚珠直立，基部托以圆盘状的珠托，受精后珠托发育成肉质、杯状、红色的假种皮。

Pollen cones terminal, solitary or clustered in leaf axils, or borne in spikelike complexes; individual cones pedunculate or sessile; microsporophylls numerous, spirally arranged, with distinct adaxial and abaxial surfaces; microsporangia 2; pollen 2(or 3)-saccate in Chinese species,.

雄球花单个顶生，或者在叶腋簇生，或者形成穗状复合花序；雄球花有花序梗或者无；小孢子叶许多，螺旋状排列，背腹面显著；小孢子囊2个；中国的种类的花粉2 (-3)气囊，。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
