INFLUÊNCIA DO ESTRESSE HÍDRICO SOBRE O DESENVOLVIMENTO INICIAL DE MUDAS DE (VIGNA UNGUICULATA (L.) WALP.) FEIJÃO-DE-CORDA

Abstract

The aim of the present study was to evaluate the influence of water deficit on the growth of french beans. The fruits were obtained in September 2019. The experiment was conducted at the Education, Science and Technology Center of the Inhamuns Region CECITEC, State University of Ceará UECE, city of Tauá-Ce. The seedlings were produced by direct seeding, in plastic cups (200ml) using 100g / cup of substrate. Four treatments (T0, T1, T2 and T3) were performed in three repetitions (P1, P2 and P3). Evaluation was performed at 15 days (initial) and 30 days (final) to determine the height, number of leaves and size of roots with the aid of a ruler. The water deficit was noticeable in the T1, T2 and T3 treatments. T1 showed vegetative development of -2.84 cm for the height of the plants; for the leaf number -2 and -3.33 cm in the root size in relation to the T0 group. The T2 group showed -2.84 cm for the height of the plants; 1.67 for the number of leaves and -3 cm in the size of the root length in relation to the T0 group. And the T3 group showed vegetative development of -1.54 cm for the height of the plants; there was no difference between the number of leaves (zero) and there was a small variation of 0.67 cm in the root size of the plants in relation to the T0 treatment. It is concluded, therefore, that the difference in water regime had a significant effect on the studied variables, modifying the development of plants.
