NUTRITIONAL DIAGNOSIS IN HYBRID COCONUT CULTIVATED IN NORTHEASTERN BRAZIL THROUGH DIAGNOSIS AND RECOMMENDATION INTEGRATED SYSTEM (DRIS)

Revista Brasileira de Fruticultura
The assessment of the nutritional status of plants by leaf diagnosis such as the Diagnosis and Recommendation Integrated System (DRIS) has stood out among traditional methods of interpreting the results of plant tissue analysis.

Photosynthesis rate, chlorophyll content and initial development of physic nut without micronutrient fertilization

Revista Brasileira de Ciência do Solo, 2013
Few studies in Brazil have addressed the need for micronutrients of physic nut focusing on physiological responses, especially in terms of photosynthesis. The objective of this study was to evaluate the effects of omission of boron (B), copper (Cu), iron

Phytophthora pseudocitrophthora, A New Pathogen of Carnations Causing Root Rot and Basal Stem Necroses in Türkiye

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
Phytophthora pseudocitrophthora is a new pathogen causing disease on carnations. It has a wide host range and is a candidate to become one of the most important Phytophthora species. There are differences between the symptoms caused by P. pseudocitrophthora and Fusarium oxysporum f. sp. dianthi, another important pathogen of carnations.

Evaluation of Chilli Breeding Lines at Multiple Locations Reveals Differential Resistance to Potyvirus Species Across Asia

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
Geographically structured populations of ChiVMV and PVMV strongly influenced the durability of potyvirus resistance in chilli across Asia. Multi‐location evaluation revealed that resistance gene combinations, particularly pvr1 + Pvr4E + pvr6 + CVMV3 and pvr1 + CVMV3, provided more stable resistance across diverse virus populations. ABSTRACT Potyviruses,

Spatial Variation of Acidic Sodic Soils in High‐Andean Environments and Theoretical Estimation of Gypsum Requirement

Soil Use and Management, Volume 42, Issue 3, July‐September 2026.
ABSTRACT High‐Andean forage systems are characterized by extensive management of cultivated forages, primarily through rotation of forage oats (Avena sativa) and alfalfa (Medicago sativa), under marginal edaphoclimatic conditions. Within this context, soil sodicity severely constrains the productivity of these systems in the districts of Ayaviri and ...

Early evolutionary history of the seed

Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Monitoring nitrogen nutrition in cotton Monitoramento da nutrição nitrogenada do algodoeiro

Revista Brasileira de Ciência do Solo, 2010
Both N excess and deficiency may affect cotton yield and quality. It would therefore be useful to base the N management fertilization on the monitoring of the nutritional status.
