Aim The relation of plant dispersal syndromes with insular species richness patters remains one the challenges in island biogeography, especially as people have affected distribution patterns. This study disentangles how influence relationship area and isolation while also accounting for human impact on biodiversity. It builds potential islands at mesoscale similar origin to contribute ongoing ...

Microplastics may enter the soil in a wide range of shapes and polymers. However, little is known about effects that microplastics different shapes, polymers, concentration have on properties plant performance. To address this, we selected 12 representing (fibers, films, foams, fragments) mixed them each with at 0.1, 0.2, 0.3, 0.4%. A phytometer ( Daucus carota ) grew pot during 4 weeks. Shoot,...

Cell division and expansion are growth events that contribute to the developing shape, or morphogenesis, of a plant. Division and expansion are coordinated to the extent that plant organs, such as leaves, generally portray a predictable cellular pattern. To dissect the relationship between division and expansion, and to test for the role of each during morphogenesis, we have identified a recess...

An investigation was carried out at the Research Farm of Olericulture Division of Horticulture Research Centre of Bangladesh Agricultural Research Institute (BARI) to evaluate the heterotic performance in F1 generation of tomato. The hybrids showed significant variation in heterosis. The highest heterobeltiotic effects were observed in the cross P3 x P8 (-18.46%) for earliness, P1 x P6 (8.57 %)...

This paper presents a simple and computationally good method for plant species recognition using leaf images. Recognition of plant images is one of the research topics of computer vision. The use of shape for recognizing objects has been actively studied since the beginning of object recognition in 1950s. Several authors suggest that object shape is more informative than its appearance properti...
