| Abstract:
- Growth and Biomass Production of Plantago major and Plantago tomentosa Considering Spaces and Arrangement of Plants In the genus Plantago, Plantago major had confirmed medicinal characteristics, as expectorant, antidiarrheal, cicatrizant and astringent. In Mato Grosso do Sul State (Brazil), as that specie as P. tomentosa, with antibacterial action, had been used indistintively for sore throat. The objective of this work was to study growth and biomass production of P. major and P. tomentosa as a function of three spaces and two arrangements of plants. Plant arrangements of three spaces among plants (0.20; 0.30 and 0.40 m) and two rows in plot (spaced 0.54 m and 0.36 m, respectively) and established in a 3 x 2 factorial scheme in a complete randomized block design, with four replications, were studied. P. major plants were more vigorous than P. tomentosa plants. Leaf area and dried matter and number of leaves grew linearly from 70 until 115 days after transplant. The highest leaf area values of P. major (4495.65 cm²) and P. tomentosa (2356.49 cm²) were obtained under the arrangement of two rows of plants. P. major produced, in general, more dried mass of leaves (38.34 g.plant-1, under two rows and 0.40 m among plants) than P. tomentosa (17.72 g.plant-1, under three rows and 0.40 m among plants). The maximum number of leaves was 37 for P. major and 75 for P. tomentosa. The number of ears of P. major varied from two to eight and of P. tomentosa from two to ten. For P. major, it can be recommended gathering of plants at 115 days or at 85 days after transplant if there is also gathering of re-sprouting. For P. tomentosa, it is advisable to gather at 115 days. | |
