Sustainable intensification of oil palm plantations faces the challenge decreasing soil fertility and increasing price inorganic fertilizers. Organic matter plays an important role in maintaining fertility. Empty fruit bunches (EFB) are main co-product mills that have potential to be used as a source organic nutrient sources. This study aims reveal effect application empty effectiveness substit...

Experiment on evaluation of mango genotypes under high density planting system was conducted in six varieties the same age group (5 years). The observation tree characters indicated that trunk circumference ranged from 20.51 cm (Prior) to 31.29 (Chandrakaran) and crown diameter 2.39 m (Ratna) 3.09 (Vellaikolumban). qualitative data morphological viz., tree, leaf, inflorescence, fruit, stone see...

BACKGROUND Flowering synchrony and floral sex ratio have the potential to influence the mating opportunities and reproductive success through female function. Here, we examine the variances in synchronous display of female and male function, ratio of male to female flowers per day and subsequently reproductive output in small populations of two monoecious plants, Sagittaria trifolia and Sagitta...

BACKGROUND A huge variety of plant forms can be found in nature. This is particularly noticeable for inflorescences, the region of the plant that contains the flowers. The architecture of the inflorescence depends on its branching pattern and on the relative position where flowers are formed. In model species such as Arabidopsis thaliana or Antirrhinum majus the key genes that regulate the init...

We have investigated the effects on plant development of mutations in the Arabidopsis thaliana CLAVATA1 gene. In clavata1 plants, vegetative, inflorescence and floral meristems are all enlarged relative to wild type. The apical meristem can fasciate in the more severe mutant alleles, and this fasciation can occur prior to the transition to flowering. Flowers of clavata1 plants can have increase...

Factors underlying apparent floral sexual dimorphism were examined in six species of andromonoecious Solanum section Lasiocarpa (Solanaceae). Both multivariate and univariate analyses show that hermaphroditic flowers are significantly larger than staminate flowers for all features measured. Thus, flowers could be characterized as sexually size dimorphic. However, when size variation due to flow...
