Residual Effect of Green Manure with Different Grass/Legume Ratios on the Sequential Cultivation of Broccoli and Brachiaria

Physiological and metabolic responses in broccoli plants fertilized with green manure

“…In this context, glucose and fructose were the Watthier et al (2022) Physiological and metabolic responses in... sugars in greater quantity and differed from control, thus indicating that the higher amounts of glucose in plants fertilized with 100JB were the result of a lower drain force (starch accumulation), which would be associated greater plant growth in this treatment (Figure 2). Furthermore, starch is a transient form of carbon storage that accumulates in the leaves during the day and is remobilized during the night to support growth and metabolism (Stitt & Zeeman, 2012).…”

“…However, in conditions of low N availability, the synthesis of carbonated and nitrogenous compounds essential for plant growth, such as amino acids, carbohydrates, proteins and other compounds used in photosynthesis, is largely affected (Nunes-Nesi et al, 2010). Studies on the use of green manure in vegetable cultivation are booming (Peralta-Antonio et al, 2019;Silva et al, 2019;Watthier et al 2022), however, little or nothing is known about the effects of these fertilizers on photosynthetic rates and the accumulation of carbon and nitrogen compounds. Thus, the objective of this work was to investigate changes in gas exchange, chlorophyll fluorescence and biochemical activity in broccoli leaves fertilized with different green manures.…”

“…Since the incorporation of inorganic N into amino acids requires a C skeleton, a delicate balance between N and C must be achieved by the plant (Alvarez et al, Watthier et al (2022) Physiological and metabolic responses in...…”
