deforce

The process of initial culture showed quite difference in various hostas . h . ventricosa and h . “ so sweet “ were easier , while h . “ frances williams “ and h . “ gold standard “ were difficult . using shoot tip ( peak bud ) as explant was proved the effective method for improving survival ratio when hostas would defoliate or have defoliated in autumn or winter rather than in summer 玉簪屬不同種類的組培初代建立存在著一定的差異,如h . ventricosa和h . ‘ sosweet ’較容易建立,而h . ‘ franceswilliams ’和h . ‘ goldstandard ’比較困難;應在冬季玉簪屬植物將要落葉或已落葉后取莖尖(頂芽)進行初代建立,最好避開夏季,來提高初代建立的成活率。

The quantity of increased leaf efficiency contributed to the aboveground biomass gain after defoliated are different at different irradiance . at the initial stage , the increased leaf efficiency of defoliated plants contributed more to biomass increment of aboveground under higher light level than those under lower irradiance . as the treatment time extended , the contribution to growth of increased leaf efficiency of plants under intermediate light level went beyond those under full irradiancy ( 2 )葉受損的植株葉效率顯著高于未受損植株;光照強度越高,植株的葉效率越高;受損植株增加的葉效率在不同光照條件下對生長的貢獻大小不同,處理初期,全光照下葉損失植株增加葉效率對地上部分的生物量增加貢獻大于中度光照,大于低光照下植株,隨處理時間的延長,中度光照下的植株增加葉效率對生長的貢獻逐漸超過了全光照下植株。

Both reduced irradiance and defoliation caused decreased slm ( specific leaf mass ) . ( 4 ) generally , chlorophyll content and chlorophyll concentration increased with reduced light levels , the ratio of chlorophyll a to chlorophyll b of defoliated plants was higher than those of controlled plants , while in latter period , the results were contrary to that of the former period ( 4 )葉綠素含量和濃度總體上都隨光照水平的降低而升高,葉綠素a / b在高光條件下顯著大于低光水平下的植株,葉損失植株的葉綠素a / b值處理初期小于未受損植株,處理后期則大于未受損植株。

Look at the jungles in brazil , the environmental abuse there , the destruction of the forests there , the rain forests . the land is being defoliated and that results in floods . and these are not unrelated to the problem of overpopulation 在巴西叢林里,也有環境破壞的問題,他們破壞那里的雨林區,在土地上施放落葉劑造成水災,這和人口過多的問題也有關系。

Say the jungles in brazil - the environmental abuse there . the destruction of the forest there , the rain forest . the land , it s being defoliated and that results in floods 在巴西叢林里,也有環境濫用的問題,他們破壞那里的雨林區,在土地上施放落葉劑造成水災,這和人口過多的問題也有關系。

The light saturation point was lower of defoliated plants than that of non - defoliated plants . with reduced light irradiance , light saturation point also decreased 葉損失植株的光飽和點要低于未受損植株,隨光照強度的降低,植株的光飽和點逐漸下降。
