Linear relationships between cherry tomato traits

Abstract

The objective of this study was to identify the linear relationship between cherry tomato yield components. Two uniformity trials, without treatments, were conducted on Lilli cherry tomato plants in a plastic greenhouse during the 2014 spring/summer season, with the plants in two stems. Variables observed for each plant were mean fruit length, mean fruit width, mean fruit weight, number of bunches, number of fruits per bunch, total number of fruits, and total fruit weight; a Pearson's correlation matrix was used to estimate the relationship between the variables. Path analysis was then performed considering total fruit weight as the main variable and the remaining variables as explanatory. Due to the severe multicollinearity, the variable 'number of fruits per bunch' was eliminated. Pearson's correlation coefficients were significant between explanatory and main variables. Mean fruit weight has a low cause-and-effect relationship with the total weight of fruits produced. A low cause-and-effect relationship was also observed between number of fruits and number of bunches. Cherry tomato productivity is directly related to the number of fruits per plant.

<b>Organic cherry tomato yield and quality as affect by intercropping green manure

“…The number of damaged fruits (NDF) and weight of damaged fruit (WDF) were also higher in the first year (46.7 NDF plant (Table 3). These productivity values were similar to those found by Sari et al (2017) for a cherry tomato hybrid.…”

Correlations and Path Analysis in Cherry Tomato Genotypes

“…Analysis of variance revealed highly significant mean squares (P≤0.01) for all traits (Table 2), which show the existence of genetic variability among the genotypes. Similar results were observed by Sobreira et al (2009), Sobreira et al (2010), Saleem et al (2013) and Sari et al (2017). The selective accuracy estimates obtained show high experimental precision, according to the criteria of Resende and Duarte (2007).…”

Correlação entre caracteres fisiológicos e agronômicos para tomateiro

“…Observa-se que entre os teores de clorofila e massa seca foram obtidos valores de correlação de grandes a moderados. Estes resultados estão de acordo com demais trabalhos de tomateiro (Sari et al, 2017;Santos et al 2018;Diel et al, 2019). Contudo, Albino et al (2018), encontraram correlação linear positiva e significativa para o número de folhas e Reis et al (2013) relataram que as plantas com maior número de folhas apresentaram os maiores rendimentos.…”
