茎

It is made from latex, a white liquid found in the stems and leaves of many plants.

它是从植物乳汁——许多植物的茎和叶中含的一种白色液体——中提取出来的。

Summer heat, has been out of bud and leaf stems.

夏日炎炎，芽已抽出茎和叶。

From leaf, bud and shoot 81.7%, 79.8%, 84.2% callus was inducted.

叶片、芽、茎段的诱导率分别达到81.7%、79.8%、84.2%。

Stems 1 to several, 1- or 2- or several leaved, rarely leafless.

茎1到数个，1或2-叶，很少无叶的或数个。

Stem leafless; petals less than 2 mm; basal leaves including petiole less than 1 cm

茎无叶；花瓣不到2毫米；包括叶柄的基生叶少于1厘米 5 N。

Stems erect or ascending, simple or branched, leafy or rarely leafless.

茎直立或上升，单一或分枝，多叶的或很少无叶。

Any of various plants of the genus Stapelia having succulent leafless toothed cactus-like stems and large evil-smelling flowers often star-shaped.

任何属于五角星花属的植物，有肉质无叶有齿的仙人掌状的茎干和星形的恶臭的大花。

Result The results indicated that, the calli development rate from leaves inducement was lower than that from leafstalk and young stems.

以葡萄叶为外植体时，诱导的愈伤组织出愈率很低；以叶柄和茎为外植体时，愈伤组织的出愈率均较高。

The leafstalk and stem are facile induced to relaxed callis, and it could be the original of suspension culture by subculture many times. Its content of resveratol is influenced by the different parts of plant and culture condition.

葡萄叶柄和茎易被诱导产生松散的愈伤组织，且经多次继代可以用于建立悬浮培养体系；葡萄愈伤组织中的白藜芦醇含量随外植体及培养基组成的不同而有所差异。

This paper reports something about it .The callus was induced and proliferated by using young stem , leaf and leafstalk as explants .which came out in early spring . In this paper , its effects on induction and proliferation were discussed by using different kinds of explants and hormone and different physical and chemical factors.The growth circle and some physiological and biochemical factors were studied during the culture of callus, a set of rapid propagation techniques were founded, which was rapid, efficient and steady.

本文以丹参初春萌发的幼茎、叶、叶柄为外植体，探讨了不同的外植体、不同的植物生长调节物质、不同的理化因子对愈伤组织的诱导和增殖效应，研究了黑暗和光照条件下愈伤组织细胞培养生长周期以及生长周期中生理生化指标的变化特征，摸索了一套快速、高效、稳定的丹参快速繁殖技术，为丹参组织培养、次生代谢物的生产提供理论依据，为丹参快速繁殖应用于生产提供技术支持。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
