Abstract:
... In Europe, extensively managed grasslands have undergone large-scale declines due to intensive agriculture and abandonment. Their restoration supports arthropod biodiversity within farming systems. We investigated limiting factors for arthropod establishment during grassland restoration across a chronosequence of 52 restoration sites established by either natural regenerating or direct seeding. Ou ...

Abstract:
... Under conditions of labor or resource scarcity, direct seeding, rather than transplantation, is the preferred mode of rice (Oryza sativa) cultivation. This approach requires varieties that exhibit uniform seedling emergence. Mesocotyl elongation (ME), the main driver of rapid emergence of rice seedlings from soil, is enhanced by darkness and inhibited by light. Plant polyamine oxidases (PAOs) oxid ...

Abstract:
... Weedy rice is morphologically similar to cultivated rice (Oryza sativa L.). It has biological characteristics that identify it as a weed. Its important weedy characteristics, that is, early and heavy seed shattering, makes it very difficult to control. Weedy rice has not been reported to be an important weed problem in transplanted, flooded rice. However, the shift to direct‐seeded rice (DSR) due ...
