杂交植物

The preserved species may lack genetic representativity because of poor sampling. Inappropriate plantations, inadequate records and unclear kinships jeopardize endangered species to genetic confusion, inbreeding depression or outbreeding depression.

由于引种或取样的不足，容易导致被保存的物种缺乏足够的遗传代表性；盲目的引种、不合理的定植以及材料的来源不清则会导致稀有濒危植物的遗传混杂、近交衰退或杂交衰退；人为选择和生长环境的改变也容易造成濒危物种对迁地保护的遗传适应。

With plants we have conclusive evidence that the sterility of crossed species must be due to some principle.

Suppression subtractive hybridization has been widely used in medical research but less in plant science up to date.

Grass of willow leaf horsewhip belongs to herb of perennial of horsewhip female division, formal name: Verbena Bonariensis illustrious name: Purpletop Verbena, alias: Long bine horsewhip is South-American horsewhip grass, careless, originate in South America formerly of Brazil, Argentine and other places, the flower is cyme, small tubular flower is worn be born at spending cauline coping, open amaranth or lilac flower, along with spends a bine to consider individual plant tall to make an appointment with 100-150 centimeter, liu Xie is crossed opposite, the primary part of a historical period after sowing is elliptic brim somewhat notch, beautiful bine is smoked tall the Xie Zhuai after is the slightness leaf that be like willow shape the brim still has pointed notch, the bine is a square this a little bit very special, entire individual plant has cilium to feel the feeling that pricks thorn a bit, the meeting in ground of be out of office is cross of plant of fringy horsewhip female division with a few congeneric flowers, so often a few inflorescence upright among Yu Jusan and fringy model state plant appears.

柳叶马鞭草属于马鞭草科多年生草本植物，学名：Verbena bonariensis英名：purpletop verbena，别名：南美马鞭草。长茎马鞭草，原产于南美洲，花为聚伞花序，小筒状花着生于花茎顶部，开紫红色或淡紫色花，连同花茎算株高约100-150公分，柳叶为十字对生，播种后的初期叶为椭圆形边缘略有缺刻，花茎抽高后的叶转为细长型如柳叶状边缘仍有尖缺刻，茎为正方形这点十分非凡，全株都有纤毛摸起来有点刺刺的感觉，在野地里会与一些同属花为穗状的马鞭草科植物杂交，所以常有一些花序介于聚伞与穗状的中间型态植株出现。

Some ten thousand years ago, early human experimenters noted that some of these hybridized Musa bore unexpectedly tasty, seedless fruit with an unheard-of yellowness and inexplicably amusing shape.

They all have the typical structure of leaf of C4 plant, but out of the ordinary is that the structure of the midrib is alike the parallel veins and there is a layer of fiber cells between the phloem and the bundle-sheath of vein in the midrib and big parallel veins while the outer wall of the bulliform cells is less cuticularized.
