Gochnatia polymorpha (Less.) Cabrera (Asteraceae) changes in leaf structure due to differences in light and edaphic conditions Acta Botanica
Rossatto,Davi Rodrigo; Kolb,Rosana Marta.
Gochnatia polymorpha (Less.) Cabrera is a widespread Asteraceae species found in different physiognomies of cerrado (Neotropical savanna) and in forest formations of southeast Brazil. This study describes some leaf anatomy characteristics of this species and quantitatively evaluates them in relation to different environments, as well as under different light conditions. We found quantitative differences in all anatomical parameters analyzed. The results demonstrate that high leaf anatomy plasticity is an adaptive advantage that allows this species to occur in diverse cerrado conditions.

Leaf architecture and symmetry of understory tree species of an Araucaria forest Biological Sciences
Boeger, Maria Regina Torres; Pilatti, Daiane Maria; Lima, Carolina Sereneski de; Alvarenga, Allan Mauricio Sanches Baptista de; Pereto, Suelen Cristina Alves da Silva.
 Shade plants of ombrophilous forests are subjected to light-limiting conditions and need to invest in architectural structures associated with leaf symmetry to increase light capture. This study investigated the leaf architecture of six Araucaria forest tree species with distinct symmetry: Cupania vernalis, Casearia sylvestris, Schinus terebinthifolius, Piper gaudichaudianum, Roupala brasiliensis and Cedrela fissilis. We hypothesized that symmetry, associated with other traits, minimizes self-shading. Asymmetry index, petiole length, total leaf area, leaf angle, internode length and stem diameter were measured. The asymmetry index did not indicate a clear distinction between asymmetric and symmetric leaves. Leaves classified as asymmetric had higher...

Leaf Morphological Plasticity of Tree Species from Two Developmental Stages in Araucaria Forest BABT
Vieira,Willyam de Lima; Boeger,Maria Regina Torres; Cosmo,Nelson Luiz; Coan,Alessandra Ike.
This study compared the morphological and anatomical variations of the leaves of four shade-tolerant tree species Allophylus edulis (St.-Hil.) Radlk (Sapindaceae), Casearia sylvestris Sw. (Salicaceae), Cupania vernalis Cambess. (Sapindaceae) and Luehea divaricata Mart. (Malvaceae) from a fragment of Araucaria forest in two developmental stages. Morphological and anatomical traits, such as leaf and tissue thickness, leaf area, leaf dry mass, specific leaf area, leaf density and stomata density were measured from 30 leaves of each developmental stage. The phenotypic plasticity index was also calculated for each quantitative trait. The results showed that the four species presented higher mean values ​​for specific leaf area and spongy/palisade parenchyma...

Leaf morphology of 89 tree species from a lowland tropical rain forest (Atlantic forest) in South Brazil BABT
Boeger,Maria Regina Torres; Alves,Luiz Carlos; Negrelle,Raquel Rejane Bonatto.
We examined the leaf morphology and anatomy of 89 tree species growing in an area of coastal Atlantic Forest in South Brazil. The majority of the species (> 75%) had small (notophyll and microphyll) elliptical simple leaves with entire margins. These leaves presented a typical anatomical structure consisting of a single epidermal cell layer, single palisade parenchyma cell layer, and spongy parenchyma with 5 to 8 cell layers. The sclerenchyma was limited to the vascular bundles. The majority of the tree species (91%) had leaves with mesomorphic characteristics. Few species depicted leaves with xeromorphic features as would be expected in such oligotrophic sandy soil. These mesomorphic features appeared to be associated to high efficiency mechanisms for...

LEAF TRAITS AND PLASTIC POTENTIAL OF PLANT SPECIES IN A LIGHT-EDAPHIC GRADIENT FROM RESTINGA IN SOUTHERN BRAZIL Acta biol.Colomb.
Ferreira de MELO JÚNIOR,João Carlos; Torres BOEGER,Maria Regina.
Restinga formations grow on sandy spits of coastal plains, an environment whose conditions limit the growth and development of vegetal species. Studies on restinga gradients are good examples of how plants acclimate to restrictive environments. This work compares three woody species co-occurring in four vegetations of a restinga from Southern Brazil. It pinpoints morpho-anatomical attributes that favor the survival of species faced with spatial variability of soil and light conditions. Results indicate that they respond differently to environmental variables on different scales. The plastic response of morphological attributes is more marked than that of anatomical ones. Varronia curassavica and Dodonaea viscosa showed more xeromorphic features on the more...

Populational Diversity on Leaf Morphology of Maté (Ilex paraguariensis A. St.-Hil., Aquifoliaceae) BABT
Coelho,Geraldo Ceni; Mariath,Jorge Ernesto de Araujo; Schenkel,Eloir Paulo.
Maté (Ilex paraguariensis A. St.-Hil.) is a native plant from southern Brazil and a raw material for beverages. To research on population variability of the species, we compared leaf morphology of three populations from Mato Grosso do Sul (MS), Paraná (PR) and Santa Catarina (SC) States. Lamina measurements included area (A), perimeter (P), length (l), maximum width (w), distance between maximum width and lamina base (dw), base angle (BÂ), biomass (m), and the indexes: relative distance of maximum width (dw/l), ratio length/width (l/w), relative perimeter (RP= P / (l + w), rectangular area index (RAI = A / (l x w)) and leaf mass/area (m/A). We verified differences among populations on A (MS<PR=SC), l (MS<PR=SC), w (MS<PR=SC), RAI (MS=PR>SC) and...

檸檬之多胚性及雜交苗之鑑定 Taiwan Agricultural Research Institute
黃阿賢; A-Shiang Hwang.
[[abstract]]在果實發育中期及成熟期分別調查Eureka及Lisbon檸檬種子之胚數,發現不同植株或不同花粉親授粉之種子,其平均胚數在2個以下,成熟種子之單胚比率達44%至68%。以糖橙(Sugar orange)、柳橙及枳殼分別授粉於檸檬,雜交苗與株心胚苗間以葉片形態鑑別之;枳殼授粉者,雜交苗率達73%,糖橙及柳橙授粉者,不同雜交組合之雜交苗率介於27%至56%間,此應與親本間之葉片形態差異程度有關。由不同時期之胚數及雜交苗率調查結果,檸檬可稱之為少胚性的柑橘,可做為雜交育種的母本。上述以葉片形態鑑定之雜交苗,於1990年2月至4月觀察新稍的顏色,大部份均為與父本相同之綠色,新稍帶有檸檬之紫紅色或淡紫紅色者,以枳殼授粉者僅11%,甜橙授粉者介於22%至30%間,顯示除葉片形態外,以新稍顏色或上述二者同時鑑定檸檬與其他柑橘之雜交苗當較容易。
