Regrowth dynamics and morpho-physiological characteristics of Plantago lanceolata under different defoliation frequencies and intensities. [PDF]

PLoS ONE
Traditional pastures in temperate regions face limitations such as reduced growth and nutritional quality during the summer season. Plantain (P. lanceolata L.) offers advantages like increased yield and decreased nitrogen losses from grazing ruminants ...

Distribution of Non-Structural Carbohydrates and Root Structure of Plantago lanceolata L. under Different Defoliation Frequencies and Intensities [PDF]

Plants
Plantago lanceolata L. (plantain) increases herbage dry matter (DM) production and quality during warm and dry conditions due to its deep roots and drought tolerance and reduces nitrogen losses in grazing systems compared to traditional pastures. However,

Effects of time and intensity of defoliation on yield and yield components of corn

پژوهشهای زراعی ایران, 2009
In order to evaluate the effects of time (20, 40, 60 and 100 days after sowing) and intensity of defoliation (0, 33, 66 and 100%) on a corn cultivar ( three way cross 647), a complete randomized block design with split plot arrangement and three ...

Effects of Defoliation Timing and Intensity on Yield Components and Grain Quality of Quinoa (Chenopodium quinoa Willd.) [PDF]

Plants
Understanding plant tolerance to defoliation is crucial for sustainable pest management and reducing pesticide use in food production. This study explores quinoa’s (Chenopodium quinoa Willd.) responses to foliar damage, which have been largely unexamined.

Resource availability and repeated defoliation mediate compensatory growth in trembling aspen (Populus tremuloides) seedlings [PDF]

PeerJ, 2014
Plant ecologists have debated the mechanisms used by plants to cope with the impact of herbivore damage. While plant resistance mechanisms have received much attention, plant compensatory growth as a type of plant tolerance mechanisms has been less ...

Does the type of silvicultural practice influence spruce budworm defoliation of seedlings?

Ecosphere, 2021
Spruce budworm (Choristoneura fumiferana (Clem)) is the main defoliator in the boreal forest of North America, and its outbreaks have major ecological and economic consequences and represent a challenge for forest management.
