Use of Growth Regulators in Cotton Production
Cotton (Gossypium hirsutum L.), a perennial woody shrub with an indeterminate growth habit, evolved in tropical, relatively dry areas of the world. Through adaptive changes, accomplished through breeding and sele...

Growth and Development of Root Systems
The importance of the root system to productivity has been acknowledged for nearly a century (Weaver, 1926). It is common knowledge that roots serve as an anchor to the plant and act as the means by which the ...

Morphometric Analysis of Chloroplasts of Cotton Leaf and Fruiting Organs
We examined morphological and ultrastructural differences in chloroplasts of cotton leaves and the fruiting organs, bract, and capsule wall to advance our understanding of their commonly observed differences i...

Ontogenic Changes in Epicuticular Wax and Chloroplast Integrity of a Cotton (Gossypium hirsutum L.) Leaf
The progressive decline in cotton leaf photosynthesis with season could be accounted for by gaining an insight into ontogenic changes in chloroplast integrity and epicuticular wax ultrastructure. Therefore, th...

Influence of Potassium Deficiency on Photosynthesis, Chlorophyll Content, and Chloroplast Ultrastructure of Cotton Plants
In cotton (Gossypium hirsutum L.) grown in controlled-environment growth chamber the effects of K deficiency during floral bud development on leaf photosynthesis, contents of chlorophyll (Chl) and nonstructural s...

Photosynthetic Capacity and Carbon Contribution of Leaves and Bracts to Develo** Floral Buds in Cotton
During ontogeny of Gossypium hirsutum L. floral buds (squares), increases in area and dry mass (DM) of floral bracts and the subtending sympodial leaf followed a sigmoid growth curve with increasing square age...

Relationships Between Nitrogen Content and Net Gas Exchange Components of a Cotton Leaf During Ontogeny
Relationships between leaf nitrogen (N) content and leaf gas exchange components of a single cotton (Gossypium hirsutum L.) leaf subtending the fruit during ontogeny were investigated under field conditions. A...

Decline in photosynthesis as related to alterations in chloroplast ultrastructure of a cotton leaf during ontogeny
Field studies were conducted to investigate ontogenic changes in leaf photosynthesis and chloroplast ultrastructure of a single cotton (Gossypium hirsutum L.) leaf subtending the fruit. A 20-d old leaf was the...

Chapter
Physiological changes during the development of potassium deficiency in cotton
Growthroom and field studies were used to study the physiology of the onset of K deficiency in cotton (Gossypium hirsutum L.) in order to explain the poor yield response to foliar-applied K fertilizer. This repor...
