Camera-based 3D reconstruction of physical objects is one of the most popular computer vision trends in recent years. Many systems have been built to model different real-world subjects, but there is lack of a completely robust system for plants. This paper presents a full 3D reconstruction system that incorporates both hardware structures (including the proposed structured light system to enha...

Leaf size varies by over a 100,000-fold among species worldwide. Although 19th-century plant geographers noted that the wet tropics harbor plants with exceptionally large leaves, the latitudinal gradient of leaf size has not been well quantified nor the key climatic drivers convincingly identified. Here, we characterize worldwide patterns in leaf size. Large-leaved species predominate in wet, h...

A major component in a crop growth model is leaf area development, which has a major influence on photosynthesis and transpiration. The knowledge about the leaf area development of wheat especially in high temperature environments is incomplete. The aim of this study was to quantify leaf production and senescence of 15 spring wheat cultivars. Field experiments were conducted at the research far...

Many arthropod species have evolved to thrive only on the leaves of a particular species of plant, which they must be capable of finding in order to survive accidental displacement, developmental transitions or the changing of the seasons. A number of studies have tested whether such species select leaves to land or oviposit on based on their color, shape or size. Unfortunately, many studies di...

A leaf-disc-test method was used under controlled laboratory conditions to determine the feeding preference of Altica deserticola Latreille (Coleoptera: Chrysomelidae) on leaves two liquorice species, Glycyrrhiza inflata Batalin and G. uralensis Fisch. ex DC. Leaf hardness thickness, cuticle nitrogen tannin contents were compared between liquorices explore their resistance A. deserticola. The l...

BACKGROUND AND AIMS Despite long-held interest, knowledge on why leaf size varies widely among species is still incomplete. This study was conducted to assess whether abiotic factors, phylogenetic histories and multi-trait interactions act together to shape leaf size. METHODS Fifty-seven pairs of altitudinal vicariant species were selected in northern Spain, and leaf area and a number of func...

rounded leaf tip. The leaf collar marks the junction of the leaf blade and sheath and appears when the leaf is fully developed. Each leaf sheath originates at its own node on the plant stalk. The sheath surrounds and strengthens the stalk (culm). The flag leaf is the last to emerge on the plant and is considerably smaller than the other leaves. The panicle (head) emerges from the flag leaf shea...

In situ and light-saturated net photosynthetic rates per unit leaf area were greater in cotton (Gossypium hirsutum L.) plants grown in pots in the field than in similar plants from a phytotron growth chamber. Light-saturated stomatal resistances did not differ in leaves of similar age and exposure on field and chamber plants; lower photosynthetic rates in chamber leaves were associated with gre...

Leaf size and shape are mainly determined by coordinated cell division and differentiation in lamina. The CINCINNATA (CIN)-like TEOSINTE BRANCHED1/CYCLOIDEA/PCF (TCP) transcription factors are key regulators of leaf development. However, the mechanisms that control TCP activities during leaf development are largely unknown. We identified the TCP Interactor containing EAR motif protein1 (TIE1), ...

Abstract In vitro-propagated potato plantlets are commonly used in seed tuber production. Four experiments were carried out to identify how the duration of last vitro phase (‘age’) before planting vitro-produced affects early growth and development ex vitro, assessed 10–14 days after planting. Experiments included varying ranges age at (10–40, 15–45, 14–28 14–56 old moment respective experiment...
