Allelopathic potential of Borreria palustris extracts

Abstract

Allelopathy can be defined as the interference of one plant over the development of another by
the release or decomposition of chemicals. The objective of this work was to evaluate alcoholic
and aqueous extracts of the aerial part of Borreria palustris, on the germination of bean and
cucumber seeds. The seeds were germinated on paper rolls. For each treatment, 20 seeds
were used in 10 replicates. The rolls were placed in germinators at 25 ° C and photoperiod of
12 hours, for seven days. Normal and abnormal seedlings, non - germinated seeds, shoot length
and roots of cucumber and bean seedlings were evaluated. The results underwent transformation,
y = √ (arcsen (% / 100)). Borreria inhibited seed germination and the development of
cucumber roots. It did not affect the growth of the bean roots and stimulated the growth of the
aerial part of the same ones. It is important to note the need for chemical studies of the extracts
of Borreria and the continuity of the evaluations.
