Agricultural practices for the culture of Xanthium strumanium L. (guizazo de caballo) with therapeutic aims

[摘要] INTRODUCTION: Xanthium strumarium (guizazo de caballo) is among the plants with antimitotic activity. OBJECTIVES: to determine in this species the agricultural features to guarantee the appropriate plant material. METHODS: during 2007-2009 studies were conducted to assess to sow dates: June and July; two sow distances 90 x 30 cm and 90 x 50 cm at two sow periods: three months of age (aerial parts and roots) in plants with a flowering-fructification states and four months of age (only roots) in plants in fructification process. Seeds obtained from wild aerial plants were sowed in plots, three repetitions in each case. The plants height was assessed at the harvest moment, choosing 10 plants/lots and 39 plants/lots were growed at a 90 x 30 cm distance and 24 plants at the 90 x 50 cm distance, in the case of foliage the yields of 10 plants/lots were assessed in each case. RESULTS: there was that at culture the plants heights were higher in those sowed in June at a 90 x 30 cm distance while those sowed in July behaved in a similar way independently of the sow distances used and in correspondence with it, the yields were similar; however, when we desire to grow also the roots, it is preferable to grow at three months of age, and in this case, the higher values were in sows of July at a 90 x 30 cm distance. CONCLUSION: for the plant exploitation with a double aim: aerial parts and roots, since in both there is antimitotic activity, sow must to be performed between June and July at a 90 x 30 cm distance and to harvest the material at three months age.
