Pamplona, Norte de Santander, Colombia. Received: June 12, ; accepted: October 01, A study was conducted to determine the variables that estimated the leaf limbo area and the leaf limbo dry weight of peach Prunus persica L. Batsch cv. Fifty leaves, aged 2. The results allowed to obtain regression equations mulfiple estimating the leaf area and the limbo dry weight.

The best equations found with an R2 of 0. Key words: Fruits, regression models, leaf limbo length, leaf limbo width. Palabras clave: Frutales, modelos de regresión, largo del limbo foliar, ancho del limbo foliar. Mathematical models are a simplified representation of lniear systems allowing one to understand, explain, estimate or predict the reality Heiner, ; Thornley,cited by Curiel dl al. In this regard, linear and myltiple regression methods and experimental variables data associated with plant organs, such as leaf area and dry weight among others, enables the construction of mathematical models to estimate the plants photosynthetic capacity.

Studies on the methods of estimating the leaf limbo area are in most cases costly, mu,tiple consuming and sometimes it may cause severe plant damage. Casierra et al. It is, therefore, important to establish mathematical models based on simple measures that can estimate the area and dry weight of the leaf limbo without damaging plant material. There is a close relationship between the leaf limbo area and its linear parameters e.

Factors that can predict the production of dry weight, such as the amount of chlorophyll, temperature and photoperiod, have been directly related to the leaf area Campostrini and Yamanishi ; Birch et al. Several authors have shown that the variation of the leaf area is multi;le most significant factor in the variation of dry weight what is experimental method in marketing research by retression Gutiérrez and Lavín, ; Astegiano et al.

It has linear equations in one variable class 8 notes ncert been shown that the plants photosynthesis capacity is directly related to the limbo surface expressed as leaf area index Kozlowski et al. In the case of peach [ Prunus persica L Batsch] its photoassimiliate production is mainly in leaves and its size what is a linear system definition to the leaf area Marquínez and Corchuelo, The how do you calculate multiple linear regression fo index LAI is one of the most commonly used parameters for the structural analysis of crop canopy and it relates the plants leaf area with the section of ground area Arias et al.

The How do you calculate multiple linear regression of this specific percentage is known as critical leaf area index and is determined by leaf area per plant Montaldi, ; De la Casa et al. Therefore, the aim of this study was to generate an empirical mathematical model applying multiple linear regression techniques, in order to estimate the leaf limbo area and leaf limbo dry weight of peach plants [ P. Characteristics of the experimental farm. The geo-referenced position of the peach trees P.

Jarillo and their llinear age pinear to six years were considered rdgression the selection of the Las Delicias farm, located in the Province of Pamplona, Colombia Chíchira. Fifty sample leaves, aged 2. Estimated leaf area using non-destructive method. The leaf limbo length LLL and the leaf limbo width LLW of how do you calculate multiple linear regression photosynthetically active and mature peach leaves were determined according to the reported procedure Kumar, Statistical analysis was performed with the calcluate of the statistical software package R and a scatter diagram was generated according to Murillo et al.

The X-axis represents the product length x width of the leaf limbo area and the Y-axis the leaf limbo area. In order to estimate the leaf how do you calculate multiple linear regression the models used by Bianco et al. An alternative model by Ruiz et al. Estimated dry weight using non-destructive method. The dry weight of the fifty leaves was measured using a forced air circulation oven and an electronic scale. A total of fourteen variables were used according to the methodology applied by Venturieri in in order to obtain an estimated dry weight model:.

Statistical analysis was performed with the aid of the statistical software package R. Correlation, simple and multiple linear regression analysis and Stepwise was used according to Bendel and Afifi Regression methods to determine how do you calculate multiple linear regression area of plants are an economic and useful tool in agronomic and plant physiology research Casierra et al.

It is also used to calculate the source-sink strength of leaf area and dry weight Marquínez y Corchuelo, As were reported for many species, such as P. Therefore, in accordance with previous studies, the most appropriate mathematical approach to develop regression estimators and equations by using measured leaf parameters such as length and width were used. As a lineag, the present study indicates that the leaf limbo predator-prey relationship graph worksheet answer key and width of P.

The regression equations generated from the leaf limbo and leaf limbo dry weight were obtained using descriptive statistics: minimum value, 25th percentile, mean and median, standard deviation, coefficient of variation, 75th percentile and maximum value Table 2. It is important to highlight that the analyses of the fourteen variables using mulfiple Pearson coefficient Table 3 showed that there was close relationship between them, thus allowing the selection of the independent variables more accurately: leaf limbo area and dry weight Sokal y Rohlf, A Stepwise regression procedure was used to calculate the leaf limbo area and dry weight of P.

Jarillo and the independent variables are given in Tables 2 and 3. The statistical results of the thirteen estimation models obtained from such procedure are shown in Tables 4gow6 and 7. It should be noted that the R2 in all models were how do you calculate multiple linear regression to 0. Therefore, from a statistical perspective any of the applied methods can be used to estimate leaf limbo area and dry weight of P. Nevertheless, from a practical point of view, the ones that take jou account the leaf's limbo length and width are considered optimal.

It is also important to emphasize that the models obtained from the present study confirms the assumptions of simple and multiple regressions methods such as normality errors, non-autocorrelated errors and homogeneity of variance, similar to those in Carica papaya Cardona et al. In order to determine a what is a phylogenetic tree how is one created model to predict nondestructive leaf limbo area of P.

Jarillo, six equations were generated and evaluated Tables 4 and 5. The first regression model analyzed, when using the product of the leaf's limbo length and width LLL x LLW with a proportional coefficient b 2as found in other species such as Persea bombycina Chattopadhyay et al. The caclulate multiple lineal regression model used to estimate the leaf how do you calculate multiple linear regression area with two proportional coefficient b 2 and b 3 ; also found in Vitis vinifera Legorburo et al.

In this regard, when evaluating the results of the lineaf equations, the 0. Jarillo and in other varieties of P. These findings are similar to those of Calulate tabacum Bozhinova,Actinidia deliciosa Mendoza et al. Therefore, the results reported in the present study, together with previous reports in mulitple species such as O. Jarillo with an R2 of 0. This confirms that leaf length and width measurements are the most frequently dimensions used to calculage leaf limbo area as it can be easily used in the field due to its simplicity and accuracy Mendoza et al.

As mentioned previously Stepwise analysis regression was also performed to predict dry weight of P. Jarillo leaves and seven equations were generated and evaluated Tables 6 and 7. Results showed that the best equation to calculate dry weight with a 0. These mulfiple confirm those of O. To summarize we can conclude that the present study validated the models and methodology Demirsoy et al. It is important to highlight that these models meet statistical parameters and are adjusted to the Colombian tropical conditions.

The models analyzed in this oinear can be how do you calculate multiple linear regression to why do dogs like to eat tissue paper the leaf area and dry weight of peach trees. The most practical options multipoe estimate the limbo leaf area of peach plants, P. The simple lineal and multiple regressions showed that the chosen mu,tiple to calculate the models are linearly related to the leaf limbo area.
