Abstract:

Plagiotropism (angle departure from orthotropic growth) was measured on 360 Norway spruce (Piceaabies (L.) Karst.) clones propagated in 2 subsequent years. The clones were members of 20 full-sib families (18 clones per family) from a provenance hybrid factorial cross involving 10 parents of Norwegian (N) and 10 parents of east-European (EE) origin. The clones from the EE × EE crosses showed an average of 17° and 20° in plagiotropism, those from the N × N group showed 3° and 7° in plagiotropism, while the hybrids (EE × N and N × EE) showed 8° and 13° in plagiotropism in 1988 and 1989, respectiv

Abstract:

Paspalum vaginatum Swartz stems growing in different directions (tillers, stolons, and rhizomes) were studied to determine the effect of sucrose on the phenomenon of plagiotropism. Sucrose content was found to be notably lower in erect stems than in stems growing horizontally. Plants sprayed with gibberellic acid underwent upward curvatures of stolons and showed a remarkable decrease in sucrose content of stolons and rhizomes. An exogenous supply of a 0.03 M sucrose solution to stolons did not significantly reduce the negative gravitropic curvature induced by excising them from the parent plan

Western larch (Larixoccidentalis Nutt.) in the interior northwestern United States produces small and infrequent cone crops resulting in recurrent seed shortages throughout much of its range. Vegetatively propagated planting stock could potentially alleviate shortages of seedlings for artificial regeneration. In a greenhouse study to evaluate suitability of rooted cuttings for forestry, morphology and growth of container-grown stecklings from 1- and 3-year-old ortets were compared with seedlings for up to 6 years after rooting. Newly rooted stecklings produced an average 50% orthotropic, 32% p

Abstract:

Abstract Timing of severance, auxin treatment, and staking were evaluated for their effects on reducing abaxial-concave bending of softwood Fraser fir [Abies fraseri (Pursh) Poir.] stem cuttings. Cuttings collected 21 July 1983, were much less plagiotropic after a 135-day rooting period than those collected 3 weeks earlier. This upright habit was related to stronger internal support from increased amounts of xylem and lignified pith at severance. Staking also reduced abaxial-concave bending, but postseverance auxin treatment had no effect. Stakes apparently provided external support until stem

Abstract— A new species of Phyllanthus with phylloclades endemic to the State of Bahia is described here. Phyllanthus dracaenoides can be recognized for its peculiar habit that resembles a species of Dracaena, a very unusual height of up to 7 m, the plagiotropic phylloclades spirally arranged, and its vermiform cincinni. Notes on its habitat, taxonomic affinity, conservation status, geographic distribution, illustrations, and photographs are provided.

Abstract:

Bulbophyllum bidoupense (sect. Brachystachyae) and Schoenorchis hangianae (sect. Pumila) are described and illustrated as species new for science. Both species are local endemics of the Bidoup mountain system belonging to the South Annamese floristic province of the Indochinese floristic region within Lam Dong and Khanh Hoa provinces of southern Vietnam. Schoenorchis hangianae and allied S. scolopendria are rather isolated species recognized among their congeners by plagiotropic creeping plant habit.

Abstract:

This study investigated the relationship among shoot inclination, irradiance and morphophysiological traits of basal (BL) and distal (DL) leaves in six cerrado trees with distinct leaf deciduousness. Deciduous species showed plagiotropic shoots (44º) and larger leaf area than semideciduous and evergreen species, which showed orthotropic shoots (56º and 63º, respectively). Despite larger leaf area, irradiance at shoot base in deciduous was around 85% in relation to full irradiance, while in semideciduous and evergreen only 23% of irradiance reached on BL. Likewise, maximum net photosynthesis (P

In robusta coffee, Coffea canephora, the black twig borer Xylosandrus compactus (Eichhoff) (Coleoptera: Curculionidae) causes considerable damage. Although this has been reported in many crops for years in Brazil, recently, the injury caused by X. compactus in coffee has been ignored. This present study aimed to report the current status of X. compactus in Brazil, and to investigate its attack frequency in different robusta coffee genotypes. In this study, we reported the occurrence of X. compactus in robusta coffee plants in the state of Rondônia for the first time. We also evaluated the occu

ABSTRACT Coffee is one of the main commodities of global agribusiness and of outstanding economic and social relevance for Brazil. The lack of labor and its high cost are factors that worry coffee producers, mainly during the conilon coffee harvesting, which is performed manually. This study aimed to evaluate the efficiency of a self-propelled harvester under different conditions of machine adjustment and conduction of the Coffea canephora crop and measure its influence on the cost of harvesting compared to manual harvesting.

Abstract:

The growth habit of the Hedwigiaceae has been described variously as acrocarpous, pseudopleurocarpous, or pleurocarpous. Anatomical evidence presented here indicates that Hedwigia ciliata is acrocarpous. The archegonia are terminal on the main shoot, and the branching pattern is sympodial. The main axis of each plant thus consists of a succession of subterminal innovations, rather than a single shoot of indeterminate growth. Since the plants are plagiotropic and are pleurocarpous in appearance, this growth pattern can be also called pseudo-pleurocarpous.

Most of cocoa plantations in Colombia belong to the plagiotropic type that emit branches and suckers in a disorderly way, which leads to an unbalanced development, this makes it difficult to manage. To search for cocoa plants with better architecture, we evaluated the effect of the type of the bud (orthotropic and plagiotropic), the grafting techniques (approximation and patch graft

The morphology and the anatomy of treated and control plants were compared. Treated plants produced only orthotropic sprouts, useful for micro-cutting, while control plants produced only plagiotropic sprouts. Direct connections between the orthotropic sprouts and the petiole accessory veins were observed only in treated plants. All together, these results were interpreted as consequences of disturbances in the auxin transport

Higher values of leaf/shoot ratio on mass base, individual leaf area, leaf area per shoot, leaf display index, and leaf number per shoot length were found in deciduous than in evergreen species. The differences about shoot-foliage relationship across leaf phenological groups could be explained by plagiotropic shoots on deciduous and by erect shoots in semideciduous and evergreen species. Plagiotropic shoots allow similar irra
