“…Analisis sidik lintas merupakan suatu metode statistika yang digunakan untuk menganalisis pengaruh variabel bebas terhadap variabel tidak bebas (Tiecher et al 2018). Menurut Fallahi et al (2017), analisis path atau analisis sidik lintas bertujuan untuk mengetahui variabel Karakter yang dimasukkan dalam analisis regresi bertahap adalah karakter yang memiliki korelasi nyata dengan hasil biji. Karakter yang berkorelasi nyata dengan hasil biji dapat digunakan dalam program seleksi (Prado et al 2013, Qi et al 2010.…”

Assembly and utilization of hybrid maize that tolerant low N is one of technology application to resolve limitation of N for hybrid maize in the suboptimal field. The objectives of this research were to select the genotype of hybrid maize that tolerant low N and determine the plant characters to be used as selecting indicator for hybrid maize that tolerant low N. Research conducted at the Experimental Farm of Indonesian Cereal Research Institute, Maros from June-November 2014. This research was arranged in split plot design with three replication. The main plot was the dose of nitrogen fertilizer that consisted of 0 kg N/ha (without N fertilization), 100 kg N/ha (low dose of N) dan 200 kg N/ha (normal dose of N). The subplot was 60 hybrid maize genotypes including control varieties P-27, NK-33, Bisi-2, and Bima-3. The results showed that reduction of 67,13% grain yield was observed in the hybrid maize without N fertilization and reduction of 33,08% was observed in hybrid maize with low N fertilization. Based on tolerance index in low N stress, the varieties HLN03, HLN17, HLN18, HLN24, HLN25, HLN32, HLN35, HLN39, HLN46, and HLN47 were grouped into hybrid maize genotype that tolerant low N with grain yield range 8,37 to 10,02 t/ha, and the highest grain yield was resulted from genotype HLN 32 (10,02 t/ha). Stepwise regression analysis demonstrated that some characters, those are leaf width, male flowering age, leaf aging, percentage of abnormal cobs, cob length, cob diameter, and kernel yields can be used as indicators for hybrid maize that tolerant low N.

“…Contrary to what was found in the present study, the same authors observed that fruit weight showed a strong correlation with fruit length and fruit diameter. The relationships between characteristics may change according to the cultivar or management adopted for the crop (Fallahi et al, 2017). In this way, the type of management adopted in the present study, different doses of boron and calcium applications, may have interfered with the relationships between the characteristics since boron actively participates in floral induction and maintenance of flowers in plants (Perica et al, 2001), leading to higher fruit yields and, consequently, higher yields.…”

The objective of this study was to identify and estimate the relationships between production component variables and fruit yields in tomatoes. This experiment was conducted in a randomized block design with a 2×3×3 factorial arrangement, with two tomato hybrids (Netuno and San Vito), three doses of boron (H3BO3 - 0, 2, 4 g pit1) and three calcium floral applications (no application; application every 7 days; and application every 14 days), totaling 18 treatments with four replications and 20 plants per plot. Pearson correlation coefficients were estimated between the measured variables and, after that, those with greater significance were selected for productivity with the Stepwise method and verification of multicollinearity using the number of condition and inflation factor of the variance. The correlations of the selected variables were decomposed into direct and indirect effects on fruit productivity with path analysis. There was a strong correlation between the variables, excluding the variables height, diameter and average mass of the fruits. Thus, there were cause and effect relationships between the independent variable total mass of the fruits and the principal variable total fruit yield. The variables diameter and total number of fruits did not contribute to an increased tomato production.

“…However, biological yield had a negative correlation with total anthocyanin content and antioxidant activity (Table 4). In a similar study on roselle, Fallahi et al (2017b) concluded that biological yield had a positive effect on the number of capsules per plant and plant height which may be attributed to genetic effects rather than environmental ones and these traits may be good selections for improving seed and calyx yield in roselle.…”

Influence of different irrigation regimes and planting times on the quality and quantity of calyx, seed oil content and water use efficiency of roselle (Hibiscus sabdariffa L.)

This study was carried out to examine the physiological traits, quality of calyx extract and seed oil content of roselle (Hibiscus sabdariffa L.) as affected by irrigation regimes and planting dates. The growth period from seed sowing to calyx harvesting was shortened as planting time was delayed. Stem diameter and plant height were decreased by drought stress or late planting, but calyx yield, total phenolic content, total anthocyanin content, vitamin C, and calyx water use efficiency increased under mild drought condition. In addition, antioxidant activity and calyx water use efficiency were significantly increased by late planting. It was suggested that an increase in calyx harvest index in delay in planting would be due to better photosynthesis activity and higher assimilate use efficiency because of the increase in sink capacity. Seed oil content decreased considerably due to drought stress and delay in planting date. These findings suggest that mild drought stress improves the quality and quantity of calyx and water use efficiency.
