Root System Radius of Three Cycas Species
HortScience, 2022 Knowledge about the position of tree roots is needed to understand tree biology and inform management decisions. Cycad species produce pachycaul stems and are not represented in the published studies on the relationships between aboveground tree traits ...

EFFECT OF DIFFERENT SCHEDULES OF DRIP IRRIGATION AND COMPLETE LIQUID FERTILIZER RATES ON GROWTH [PDF]
Journal of Plant Production, 2004 The present work was designed to study the effect of different schedules of ,; irrigation (every 3, 4 and 5 days as drip irrigation) and fertilizer (NPK 19:19:19) at 1.5, 3 and 4.5g/pot as liquid with the irrigation water on growth of Cycas revo/uta ...

Early evolutionary history of the seed. [PDF]
Biol Rev Camb Philos SocABSTRACT 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 ...

Identification and characterization of caleosin in Cycas revoluta pollen
Plant Signaling & Behavior, 2020 Oil bodies are essential energy storage organelles that are generally present in the seeds of plants. Caleosin protein has been identified in the seed oil bodies of Cycas revolutaseed.

Warm stratification improves embryos development and seed germination of Cycas revoluta
Advances in Horticultural Science, 2021 The broad objective of this research is to study the effect of warm stratification on Cycas revoluta zygotic embryos length, seed germination and plant development. Four warm treatments were applied to seeds. Our results showed that seeds storage at room

Phylogenetic reconciliation provides new insights into the evolutionary diversification of the glutamine synthetase gene family in seed plants. [PDF]
FEBS JPhylogenetic analyses of glutamine synthetase (GS) in seed plants revealed that all three major evolutionary lineages (GS2, GS1a, and GS1b) must have been present in the common ancestor, with GS2 being the first lineage to diverge. Unlike GS1b, GS1a and GS2 are usually single‐copy genes, even though they underwent duplications that resulted in ...
