“…The quantity, quality and duration of light and temperature, as well as the date and density of planting, soil moisture and chemical fertilization, particularly with nitrogen, affect the concentration of chlorophyll, the formation of biomass and grain yield. Chlorophyll is the primary photosynthetic pigment of plants; together with foliar nitrogen, it varies with solar radiation [16]. Leaf chlorophyll is closely related to the concentration of N, reflecting the nutritional status of the plant with respect to this important nutrient.…”

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 replications. The experimental unit consisted of two rows of five linear meters with a distance of 0.75 meters between rows. Chlorophyll was measured at six different stages: V6, VT, R3, R4, R5 and MF. The agronomic variables recorded were: PH, CH, LAC, LBC, FF, MF, PM, CC, CL, DC, RC, KR and GY. The results of the analysis of variance showed significant differences between lines, dates and their interaction. On average, 18 lines were found with chlorophyll concentrations above 51 SPAD units in the two environments. This indicated that these materials had a high potential for field performance. Using cluster analysis UPGMA method, we identified seven groups for chlorophyll and eight groups for agronomic characteristics for a breeding program. The groups were associated to the homogeneous characteristics of each variable. *Corresponding author. M. M. Elos et al.1068

“…The differences between Xin and Zhong cotton on root area parameters (TAA, AAA, PAAAR, RV and SSA) throughout the experimental period revealed the differences between nutrient efficiency cotton genotypes on uptake, transportation, accumulation, distribution and utilization (Mi, et al, 1998;Jiang et al, 2008).…”

Modern agriculture using hydroponics allows in-depth study of root morphology and physiology. Two experiments were conducted to evaluate effectiveness of mineral nutrients, phosphorus (P) and potassium (K) and phytohormones, indole-3-acetic acid (IAA), gibberellic acid, (GA 3 ) and zeatin ( Z) on cotton plant varieties root area, root volume and root activity. During the first cropping, Low P, low K and high PK treated plants significantly influenced total root absorption area, active absorption area, percentage active absorption area ratio, specific surface area and root volume. Furthermore, treatments applied did not favour root activity at the early growth stage but effects were known as from 104 to 148 days after transplanting. During the second experiment, however, cotton plants treated with hormones significantly affected active absorption area, percentage active absorption area ratio, root volume, specific surface area and root activity at 80 and 90 days after transplanting. In general, there was no relationship between the first cropping without hormones application and second cropping with hormones application except percentage active absorption area ratio (-0.999*) which was negatively correlated. This report shows effect of mineral nutrients and stimulatory tendency of hormones in root growth regardless of different cropping time between first and second cropping.

“…This signifies that hormones alter cotton plant growth whereby high P content is needed during seedling up to reproductive stage (José, et al, 2002). Xin cotton performed better than Zhong cotton in nutrients absorption capacity at 80 and 90 DAT due to their genetic variations (Jiang, et al, 2008). On the contrary, the pot treated with IAA x GA 3 x Z had significantly higher residual K-content in the nutrients solution at 43 days after transplanting.…”

“…This could be due to higher level of hormone concentrations added at day 67 after transplanting which altered cotton growth and development. Different genetic constitutions of the two varieties suggest better performance of Zhong cotton variety over Xin cotton variety (Jiang, et al, 2008).…”

Sustainable agriculture requires economical and judicious use of mineral fertilizers and other farm inputs such as synthetic plant hormones so as to benefit crop growth, development and yield. The present study investigated residual levels of phosphorus (P), potassium (K) nutrients and nutrient solution level in the hydroponics by application of low P, low K and high PK nutrients to hydroponics pots in the first experiment, and by spraying cotton plants with indole -3-acetic acid (IAA), gibberellic acid (GA 3 ), zeatin (Z) and their combinations at high level of PK nutrient in the second experiment. In the first experiment, nutrient solution level in the hydroponics irrespective of varieties of cotton planted in them and those with specific cotton varieties were significantly affected by the treatments. However, low P, low K and high PK treatments irrespective of the two cotton varieties planted in the hydroponics pots significantly influenced residual level of P and K nutrients. During the second experiment, the exogenous hormones applied irrespective of two cotton varieties planted in the hydroponics pots did not affect nutrient solution level in the hydroponics except at 43 and 80 days after transplanting (DAT). Nevertheless, taken the two cotton varieties into consideration, Zhong cotton variety had higher nutrients solution level than Xin cotton variety. In general, hormones applied did not affect residual P and K in the nutrients solution after every nutrients change except at 43 DAT. However, varietal differences were observed for high residual P and K nutrients at 80 and 90 DAT for P and 74 and 90 DAT for K in the nutrient solution grown with Xin cotton variety. It is clear from these results that wise usage of mineral fertilizers and synthetic plant hormones should be taken into consideration in order to avoid wastage.
