Abstract

Abstract: In order to comparing the effects of different methods and conditions on root research， a pot experiment with different cultivates and a field experiment by using Zhengmai 9023 and Aikang 58 was investigated in2010 － 2011 ． Results showed that， compared to the field experimental condition， root vigor was higher in pot experimental condition． Root vigor ( FW) was in a range of 24． 607 － 334． 839， 29． 362 － 298． 834 μg /( g· h) in differentgrowth stages， respectively． In a green house experiment， root vigor in different cultivate mediums was significantlydifferent， following a order: hydroponic culture ＞ perlite cultivate ＞ sand medium ＞ vermiculite cultivate ＞ soil cultivate． Under field experiment and pot culture experiment， a single root loss rate was significantly in a range of45. 7% － 70． 25% and 15． 79% － 34． 28% in the direct blunt root and screen at the single root package treatments， respectively． Results showed that， root acitivity determination value in the pot experimental condition can beas a reference for that in the field experimental condition． Indoor culture condition， to make root activity determination value comparable， matrix types should be clearly indicated． A conclusion should be made that the flushingpackage of root could get a more accurate root weight values．
