Abstract:
Twenty eight (23) H. ampla and nine (09) H. rupestris adult and young specimens were collected to determine the levels of S04~ and total-S in leaf, stem, tuber and in the soil where they grow. In H. ampla the level of S04~ varied from 022.-078% and in H. rupestris from 0.22-138%. The level of S in H. ampla varied from 0.74-0.96% and In H. rupestris from 0.75-1.02%. The level of S04~ IH H. ampla follows the pattern leaf 〉 tuber 〉 stem Independent of time of year and physiological age, while in H. rupestris the pattern is tuber 〉 leaf 〉 stem. The 5 shows a different behavior, maintaining the pattern tuber 〉 stem 〉 Jeaf for H. ampla and tuber 〉 leaf 〉 stem for H. rupestris. In the soil where H. ampla grows no variation in level of S04~ (052%) was observed while for H. rupestris the variation was from 027-0.63% being higher in the rainy season. Due to the vegetation-soil interrelationship the levels of organic C, N, P, K, Ca, Mg, Na, Mn, Fe, Al and Zn were analyzed in the vegetative material and in the soil.
