Seed vigor and initial growth of corn crop

Vigor de sementes e crescimento inicial da cultura do milho


Seed vigor is a characteristic that determines potential for fast and uniform seedling emergence and establishment of crops. Such characteristic defines crop initial growth what could have direct and indirect effects on capacity of plants in capturing natural nutritive resources and intervene in their competition intra- and interspecific. Aiming at identifying and understanding the possible effects of seed vigor on crop initial growth a field experiment was performed during two years at University of São Paulo, Piracicaba, SP, Brazil; using two seed lots at each year, which were previously characterized by tests of physiological potential as high and low vigor. Thus, five different ratios (100:0, 75:25, 50:50, 25:75, and 0:100) of seeds originating from seed lots with higher or lower vigor were used. Assessments were performed at the phenological stages of four and eight leaves by assessing plant height, stem diameter, and leaf area index. It was also observed that mean values for all variables assessed have increased according to increase of seeds with high vigor at planting row. Therefore, it is concluded that increased percentage of seeds with high vigor results in greater initial growth of cron crop until phenological stage of eight leaves.

Vigor é a característica que determina o potencial para rápida e uniforme emergência de plântulas e estabelecimento das culturas. Essa característica define crescimento inicial, o qual pode ter efeitos diretos e indiretos na capacidade da planta em capturar recursos naturais e intervir na sua competição intra e interespecífica. Objetivando identificar e entender os possíveis efeitos do vigor de sementes de milho no crescimento inicial da cultura, um experimento foi conduzido, por dois anos, na Universidade de São Paulo, Piracicaba, SP, Brasil; utilizando dois lotes de sementes a cada ano, os quais foram previamente caracterizados por testes de potencial fisiológico, como alto e baixo vigor. Assim, foram utilizados cinco diferentes proporções (100:0, 75:25, 50:50, 25:75 e 0:100) de sementes de lotes com maior ou menor vigor. As avaliações foram realizadas nos estádios fenológicos de quatro e oito folhas para altura de planta, diâmetro de colmo e índice de área foliar. Foi observado que os valores médios para todas as variáveis analisadas aumentaram de acordo com aumento de sementes com alto vigor na linha de semeadura. Assim, concluiu-se que o aumento da porcentagem de sementes com alto vigor resulta em maior crescimento inicial da cultura até o estádio fenológico de oito folhas.
