The maize and neorgelia cawlinae meyendor ffii were treated with uv - b radiation with the intensities of 0uw. cm - 2 ( ck ), 10uw. cm - 2 ( r1 ) and 15uw. cm - 2 ( r2 ), the duration of uv - b treatment were ten hours per day ( from am8 : 00 to pm18 : 00 ). the effect of uv - b radiation on the photosynthesis was studied, and the results showed as follows : ( l ) the effects of uv - b radiation on photosynthesis of maize and neorgelia cawlinae meyendor ffii the results of the experiment show that the photosynthesis of maize seedlings was restrained because of the decrease of chlorophyll contents activity of hill reaction stamotal conductance activity of pepcase and atp content caused by increased uv - b radiation, and it was more restrained under higher uv - b radiation. though the activities of rubpcase and pepcase were decreased, the chlorophyll contents activity of hill reaction stamotal conductance of mature maize were not affected, therefore the photosynthesis of grown - up plant was not affected

Cm ~ （ - 2 ） （ r2組）的uv - b輻射，每天處理10小時（ 8 ： 00 ? 18 ： 00 ） ，直至玉米成熟，以自然光照為對照（ ck組） ，對增強uv - b輻射條件下玉米和紅彩鳳梨光合作用的響應作了深入的研究和探討，結果如下： （ 1 ） uv - b輻射對玉米和紅彩鳳梨光合作用的影響研究結果表明，因增強uv - b輻射降低了玉米幼苗葉片的葉綠素含量、 hill反應活力、氣孔導度、 pepcase活性和atp含量，從而影響了玉米幼苗的光合作用，使其光合速率下降，且隨uv - b輻射強度的增加其影響程度加大；而玉米成株在增強uv - b輻射環境下其葉綠素含量、 hill反應活力、氣孔導度等未受影響，雖然其rubpcase活性和pepcase活性有所下降，但總體上其光合作用受到的影響不大。

So the foundation is set for its practical use. 4 the acting - straight - sorting and dropping plug set is designed, which can solve the sorting plugs unclearly because of the difference between individual plug seedlings, and can raise the punctuality of sorting plug seedlings and the veracity of plug seedling dropping into the lead - plug - seedling - tube, in addition, the working frequency of acting - straight cylinder is calculated by analysis to the movement and strength of the key parts in this system which can accelerate the transplanting rate to 3 plants per second, further more, a lot of operated experiments indicate that the working reliability of this set can be raised under the condition of the proper seedling transplanting speed

4採用直動? ?雙擋銷式分缽落苗系統，不僅解決了因為缽苗個體差異帶來的分缽不清的問題，而且提高了缽苗分缽的準時性和缽苗落入導苗管的準確性；同時，通過對該系統工作過程的主要工作參數的運動和受力情況分析，確定了該系統各直動汽缸的工作頻率，使分缽落苗速度達到3株/秒以上，進一步通過大量試驗對其進行驗證，證明了該系統在滿足栽植速度要求的前提下，可以大大提高了系統的工作可靠性。

It showed that the induction efficiency of the resistant calli were the same among all explants of different age, but the embryos on the calli from explants of 7 days appeared earlier than those from explants 11 and 30 days. in order to compare the resistant calli induction efficiency, petioles and hypocotyls were excised from 30days aseptic seedlings to transform with pbinctbs under the same condition. the resistant calli induction efficiency of petioles was higher than those of hypocotyls. a more detailed analysis of the different types of explants showed that the number of pcr positive plants induced from petioles was higher than that from hypocotyls
