There was close relationship between fresh weight of stolon with cormel and new corm , that is increase in fresh weight of stolon and cormel followed the conns at early and middle stage, but surpassed it finally.

匍匐莖和子球的鮮重與新球鮮重密切相關(guān)操干网在线，前期增長(zhǎng)趨勢(shì)與新球鮮重增長(zhǎng)趨勢(shì)一致，后期的增長(zhǎng)趨勢(shì)明顯快于新球中国特大性交无码视频。

The numbers of stolon increased in the trend of "slow-fast-slow", but the increasing of cormel number was almost linearity. Yield of cormel was improved by delaying planting time to the end of May.

Gladiolus cultivar "Traderhorn" and "Advanced Red" were used to investigate the growth and development of stolon and cormel, changes of starch and soluble protein content during stolon development in the field with different planting times. Meanwhile, studied the factors which affected cormel formation in vitro.

In the first stage, the initial of morphologization of cormel happened, corresponding with the period from 4 leaf to full-blown, the growth and development of stolon mainly occured, while the number of cormel was a few and its weight slowly increased.

With the basal stem of short spike L.brevitaba and its coterminous stolon, clonal ramet taken from grasslands which were non-degraded, light-degraded, moderate-degraded and heavy-degraded as the materials, the differences of stolon number and its length and the dry weight per unit of length of short spike L.brevitaba stolon from different degraded grassland were studied.

Under field continuous drought stress, growth rate, branches of stolon, leaf lengthobviously declined, nevertheless, leaf water content increased and MDA content decreasedsignificantly during field water deficit. SOD activity of the four turf grasses increased at thebeginning of water deficit and then decreased with drought stress. POD activity ofAugustinegrass increased rapidly and then kept stable with water deficit, however, PODactivity of Centipedegrass changed indistinctively.

The characteristics of clonal growth and resources sharing were important to keep stability of community. The transpiration and the stomatal conductance of stolon with and without adventitious roots were same. But the water potential of stolon without adventitious roots was higher than that with adventitious roots.

In the same observation time, the number of maternal ramets and daughter ramets, the total length and the number of stolon and branching intensity of P. flagellaria clone population were higher than P. anserina. But the average length of spacer and stolon of P. anserina were more than P. flagellaria.
