Factors Influencing Collecting Amount of Rice Roots Bleeding and Investigation on Roots Vigor After Heading
摘要
Abstract
In the present paper, we first discussed the factors that influenced the rice root bleeding collecting by using absorbent cotton absorbing methods It can be condudcd that it was best to use 2.0g absorbent cotton to collect the bleeding during, the heading stags of Liangyoupeijiu (LVPJ); there was significantly difference between LYRJ's stem and the tiller (P< P>0.05), (here was no difference between the first time and the secomd time of mowing rice stake(P>0.05) Undet the direction of above methods, we studied the LYPJ's roots bleeding change after its heading by using Shanyou63 as CK. It was concluded that: about one week after their heading, the root vigor (roots bleeding intensity) of LYPJ and its referring variety Shanyou63 all reached the highest peak, then declined. Compared with the Shanyou63, the vigor of LXPJ deelined more seriously and kept at Wlower level.关键词
