Ein neues autosomal-rezessiv vererbbares SyndromMultiple periphere Pujmonalstenosen, Brachytelephalangie, Innenohrschwerhörigkeit, Knorpelverknöcherungen bzw. verkalkungen* Bei zwei von fünf Kindern aus einer Ehe blutsverwandter Eltern wurde ein bisher nicht beschriebenes, wahrscheinlich autosomal-rezessiv vererbbares Syndrom von multiplen peripheren Pulmonalstenosen, Brachytelephalangie, Innenohrschwerhörigkeit und abnormen Knorpelverkalkungen bzw. -verknöcherungen beobachtet. Eines der Kinder, ein Mädchen, hat eine einseitige, die Mutter eine doppelseitige Fusion der Ossa multangula.Genetische Aspekte kardiovaskulärer und assoziierter Fehibildungen sind ein nicht nur wisseischaftlich, sondern wegen der Möglichkeit und Notwendigkeit einer fundierten Familienberatung auch praktisch zunehmend wichtiges Problem. Im folgenden wollen wir ein bisher offenbar nicht bekanntes, sehr wahrscheinlich autosomalrezessiv vererbbares Syndrom vorstellen.
KasuistikDie Probanden, Hildegard D., geboren am 26. 11. 1958, und Karl-Josef D., geboren am 23. 5. 1961, sind zwei von fünf Kindern blutsverwandter Eltern: Der vater der Mutter ist ein vetter des vaters (Abbildung 1). Außer bei den beiden Patienten sind Herz-oder Gefäßkrankheiten in der Familie nicht bekannt; nur ein Neffe des * Abbildungen 2-3 und 6-9 siehe Tafel Seite 1665 und 1666.
The aim of this study was to characterize the phenology of different sweet orange, tangerines and tangerine hybrid varieties growing under the temperate climate conditions of Santa Fe Province, Argentina. Phenological stages were observed weekly during five consecutive years using a BBCH (Biologische Bundesanstalt, Bundessortenamt and Chemical industry) scale adapted for Citrus trees. All varieties showed a winter rest period from June to August. ‘New Hall’ and ‘Navelina’ varieties were the first to reach sprouting stage, whereas ‘Okitsu’ was the last. Inception of flowering occurred from August 13th to September 6th; and full bloom from September 12th to October 2nd. Fruit harvest started with the ‘Okitsu’ cultivar in March, and continued over a 7-month period. Interannual variation for inception of sprouting was high (44 days), and sprouting was correlated with both thermal accumulation (above 13ºC) and the amount of solar radiation measured during July (p<0.0001; r2=0.79). Navel oranges and the ‘Murcott’ hybrid bloomed 5–15 days earlier than other varieties, increasing probability of damage by late frosts.
ABSTRACT:The crop load level of an apple (Malus × domestica Borkh.) tree impacts fruit yield and quality parameters, tree vigor and biennial bearing. The optimal crop load is that which allows for consistent annual cropping and fruit quality acceptable to the market. We evaluated the effect of crop load on yield and fruit quality of two low-chill apples cv. 'Caricia' and 'Eva', growing in a mild winter area. During 2010 and 2011 crop load was manually adjusted from 2 or 3 to 17 fruits cm −2 of trunk cross-sectional area (TCSA). Fruit yield was positively related to crop load in both cultivars but mean fruit weight diminished as the crop load increased. For both cultivars, the production of non-commercial and small-sized fruit increased, whereas production of middlesized fruit diminished as the fruit load increased. Shoot length was not affected by crop load in 'Eva' whereas it was reduced in 'Caricia'. Red skin color (RSC %) had a quadratic response to crop load in 'Caricia'. On the other hand, the RSC % of 'Eva' fruit was adjusted to a negative logarithmic model as an effect of crop load increment. No biennial bearing was observed in either cultivar. This research study suggests that the maximum limit of crop load for both cultivars is 7 fruits cm −2 of TCSA, and the lower limit of crop load was 3 fruits cm −2 of TCSA for 'Eva' and 5 fruits cm −2 of TCSA for 'Caricia'.
El objetivo de este trabajo fue evaluar el enraizamiento de estacas de Croton urucurana Baill., Tabernaemontana catharinensis A. DC. y Paullinia elegans Cambess conocidas en Argentina como “Sangre de drago” (SD), “Horquetero” (TC) y “Ojo de muñeca” (PE), respectivamente. Se recolectaron 200 estacas leñosas por especie; una vez defoliadas se aplicó ácido naftalén acético (ANA) en las siguientes dosis: 0, 1000, 2500 y 3500 mg.L-1 en SD y TC y 0, 500, 1000 y 2500 mg.L-1 en PE. Se evaluó la formación y calidad de raíces y el diámetro de las estacas a la altura del cuello (DAC). En SD las dosis de ANA ≥1000 mg.L-1 aumentaron la probabilidad de enraizamiento de 0,36 a 0,71. En PE hubo baja probabilidad de enraizamiento (0,13) independientemente de la dosis de ANA, pero aumentó en función del DAC. No se observó formación de raíces en TC. La calidad de enraizamiento no fue afectada por la diferentes dosis de ANA, pero sí el DAC en SD.
