花期

The research aimed to study the flowering time regulator of Chaenomeles cathayensis and investigate its forcing culture technique.

［目的］研究木瓜海棠的花期调控，探讨其促成栽培技术。

Techniques of forcing culture of tissue culture plantlet in Hydrangea Macrophylla Ser. were studied, including Regulating growth and development of 2-year-old one by using PP333 and breaking blossom bud dormancy under natural low temperature condition in Lanzhou, in order to make the H.

研究应用多效唑调控八仙花2年生组培苗的生长发育，以及利用兰州地区的自然环境条件，在户外自然低温条件下打破花芽休眠，以期将八仙花的花期提前到春节前后。

According to several years practice, comprehensively sum up measures of forcing culture technology of scale and dwarf on potted Bougainvillea as: a propagation of cuttage, which choose a mixture of 50%peat, 33% vermiculite and 17 sharp sand as cutting soil, and choose a semi-wooden shoot cut into 5~10cm length with 2~3 leaves as cuttings then touch 1% AA root powder, is lower cost and higher survival rate than that of tissue culture; Bougainvillea growth can be efficaciously regulated by pruning and using 2~5g/L PP333; bougainvillea can be induced to flowers by spraying 2.5~4.0g/L B9 and administering no more 11 hours daylight every day continuously; the florescence can be more prolonged about 20 days by spraying 50mg/L NAA while selling; and prevention and cure of pest and disease, etc.

根据多年的生产实践，从科学育苗、栽培管理、售前处理和病虫害防治等方面综合总结了叶子花的规模化矮化促成生产技术措施：选择泥炭土、蛭石和黄沙按3：2：1比例混合均匀的扦插基质，采用半木质化当年生枝条，剪成5~10cm长的2~3叶节一段，沾染1%自制生根粉的扦插育苗较组培育苗成本低，成活率高；结合修剪用2~5g/L的多效唑进行叶面喷洒能有效控制生长，矮化植株；选择2.5~4.0的丁酰肼叶面喷洒和每天保持不多于11h的短日照处理，能有效促进开花；销售前全株喷洒脱50mg/L NAA可延长花期20天左右；整个生产过程加强肥水管理、温湿度控制和环境清洁能有效防治病虫害发生。

Pingbianensis flowers were ants (Aphaenogaster smythiesii Forel,Formicidea), springtail (Hypogastrura sp., Hypogastruridae, Collembola) and one species of beetles (Anomala corpulenta Motsch, Rutelidae). These pollinators generally have restricted movement capacities and hence promote geitonogamy or mating between individuals in close proximity within populations. The results of out crossing index pollination experiments in our study suggest that T. pingbianensis has an animal-pollinated, mixed selfing and outcrossing breeding systems.

通过对屏边开口箭的开花物候、传粉生物学、交配系统的研究以及对近交衰退的检测，结果显示：屏边开口箭单花花期约15天左右，柱头、花粉活力持续时间较长；传粉昆虫多为蚂蚁、跳虫，偶有小甲虫拜访，缺乏长距离传粉昆虫；杂交指数以及套袋试验的结果表明屏边开口箭为高度自交亲和的混交模式植物，且在幼苗早期并没有表现出明显的近交衰退现象。

Germ plasm characteristics such as initial fruitage time, mature period, blossom flower and the affinity of copulation between various types were described.

记叙了各类梅的一般性状、果实大小、始果期、成熟期、花期、花器和交配亲和性等种质特征。

The flowering process of the chinese honeysuckle was observed, and the effects of the hormone gibberellin and the trace element Boron were also investigated.

观察了金银花的成花过程，并对花期受激素及微量元素的调控作用进行了研究。

In addition, the accumulation of soluble sugar and starch were promoted, but the activity of glycolate oxidase was apparently decreased by CO2 enrichment, respectively, flowering of Guzmania 'Luna'was also promoted.

此外， CO2 加富促进了紫星凤梨叶片中可溶性糖和淀粉积累，降低了乙醇酸氧化酶活性，提前了紫星凤梨花期。

People say that when gorse is out of bloom, kissing is out of fashion.

人们说，要是荆豆过了花期，那接吻也就不合时尚了。

3 Mm. Style persistent on apex of gynobase in fruit, surpassing nutlets, ca. 0.6 mm. Nutlets obliquely narrowly ovoid, 2-3 mm, tubercles stellate pubescent at apex. Fl. Apr-May.

花药长约0.3毫米花柱宿存在雌蕊基在果期的先端上，胜过小坚果，0.6毫米小坚果斜狭卵球形，2-3毫米的约，花期 4-5月。

It implied that the moderate shading could improve contents of chlorophyll, and delay mature stage and florescence. This was important for the growth and garden applications of Hemerocallis fulva var. florepleno.

适度的遮荫可以提高重瓣大花萱草的叶绿素含量，对延缓叶片的成熟期和花期有重要的影响，同时对重瓣大花萱草的生长及园林应用有重要意义。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
