Our results provided direct evidence that pf40 gene play a role in the tissue development, with knockout this gene the lateral buds were not visible. the plant hormones auxin and cytokinin appear to play a major role in controlling this process, therefore, the concertrition of auxin and cytokinin was measured, however, the concentration of the two hormone was variation a little in transgenic plants, but the ratio of the two was more than 5 fold in the pf40 gained function plant than that in wild type. furthermore the pf40 gene effected differentiation of the vascular bundles in different transgenic plants, results showed the pf40 could change both xylary fibers and vessel
進一步的實驗發現pf40基因會影響植物側芽發育的早期，即pf40基因作用在側芽形成與發育的早期。對轉基因穀子的組織切片的分析還表明pf40基因引起不同形式的轉基因穀子的維管組織的發育的差異，轉化正義載體穀子的木質部變多，維管系統增多，而反義或干擾的轉基因穀子的木質部數量變少，木質部分化異常。從轉基因的結果可見pf40基因可以減弱植物的頂端優勢，這種作用是通過改變植物體內激素的含量實現的。The curves showed that the moisture contents of straw and the shear bar are the main factors impacting the cutting ratio besides cutting speed. the speed of 40mm / s is necessary to cut off wet straw. ( 4 ) the testing results indicate that the rotary speed of the blade axle need to be more then 1230 rpm ( rotary radius of the blade is 25cm ) to cut off straw ( with moisture content less then 20 % )
試驗結果表明，對于乾的長秸稈，刀片切割速度達到15m / s時，切斷率達100 ；對于乾的短秸稈，刀片切割速度需達到20m / m / s以上；要切斷濕秸稈需要有40m / s以上的切割線速度；加定刀與不加定刀對于切斷麥秸這類軟質秸稈是非常重要的，其切斷速度差別很大；另外，麥秸不同部位所需要的切斷速度也是不一樣的，根部較之頂部和中部更難切斷。In a hard right turn the outer third of my left wing sliced through the ufo ' s crystals with the sound of an intense hale storm on a tin roof
