Chlorophyll Concentration and Morphological Diversity in Corn Lines at Different Vegetative Stages

Abstract: The objective of this study was to assess the chlorophyll content of corn lines at different vegetative stages and the diversity between them. The study was conducted in the experimental field of the Roque Institute of Technology (ITR) located in Roque, Celaya, Guanajuato, Mexico. We used 32 corn lines from CIMMYT and four lines from the breeding program of the ITR. The evaluation was conducted in the spring-summer cycle of 2014 at two planting dates. We used a completely randomized block design with three rep… Show more

“…However, it is possible to predict relative yield with a certain level of accuracy. At the phenological stage R1, Sunderman et al (1997) and Elos et al (2016) found CI averages of 57.9 and 50.3, respectively, which is consistent with the values reported in the present finding (between 43 and 56) (Fig. 2).…”

“…Although there is a great variation in the response of different maize hybrids due to their nutritional demand, which varies not only from hybrid to hybrid but also in different stages and different edaphoclimatic conditions, the CI and leaf N concentrations found in the present work were consistent with previous studies. Other authors, using different hybrids in several climatic conditions, reported a critical CI ranging from 50 to 57 (Sunderman et al, 1997, Elos et al, 2016) and a critical leaf N level from 27 to 35 g N kg -1 (Cantarella et al, 1996). Both critical levels for these variables were found in the present study in the range of values considered ideal for grain yield, and, since they were measured at the R1 stage, they might represent a useful tool with which to predict yield at earlier stages of growth.…”
