ABSTRACT Kale (Brassica oleracea var. acephala) is mostly produced by urban growers in Brazil, but little known about the diversity and management of diseases for sustainable agriculture. The present study investigated occurrence cultivation kale two regions representing climate conditions Cwa (Lavras - MG) Aw (Campina Grande PB) according to Köppen Geiger classification, as well factors that c...

Stressful parental environments can influence offspring size and development either adaptively or maladaptively, yet little is known about species' differences in this complex aspect of phenotypic plasticity. We performed a reciprocal split-brood experiment to compare transgenerational plasticity in response to drought stress in two closely related annual plant species. We raised inbred replica...

In this study, the relationship among four species of Polygonum (including P. hyrcanicum (three samples), P. persicaria, P. avicular, and P. hydropiper) was investigated by GC profiling. Furthermore, the major compounds of the ethylic ether extract of P. hyrcanicum were identified by GC/MS as: α-bisabolol (17.5%), cedrol (15.9%), sesquisabinene hydra...
