Role of nitric oxide in soybean cotyledon senescence
(Elsevier Ireland, 2009-05)
Senescence was studied in soybean (Glycine max, var ALM 4500) cotyledons from 10- and 25-day-old seedlings. Rejuvenated cotyledons, obtained by removing epicotyls from 5-day seedlings, showed a lower decrease in the content ...
Caracterização morfoanatômica de plântulas de Gomphrena elegans Mart. (Amaranthaceae)
(2006-04-01)
Aiming to describe seedlings' morphology and cotyledons and eophylls anatomy of Gomphrena elegans Mart., 100 seeds were put into plastic bags, with sand and fertilized soil (1:3), kept in the greenhouse under room conditions, ...
Behaviour of soybean seedlings in situations involving cotyledon removal
(2020-01-01)
Cotyledons have photosynthetic and reserve functions. In initial development, cotyledon herbivory makes the majority of species more susceptible to the environment. This study aimed to reproduce herbivory situations occurring ...
Loss of cotyledons in different stages in initial bean growth
(Fundacao Zoobotanica Rio Grande Sul, Museu Ciencias Naturais, 2017-08-01)
The objective of this work was to analyze the effect of cotyledon loss at different times of initial bean growth. The experimental design was completely randomized in a factorial scheme of 2x5, seedlings with zero and one ...
Effect of phosphorus deficiency on reflectance and chlorophyll fluorescence of cotyledons of oilseed rape (Brassica napus L.)
(Wiley Blackwell Publishing, Inc, 2009-06)
The spectroscopic changes in reflectance and fluorescence caused by phosphorus (P) starvation in Brassica napus L. young plants were evaluated. P deficiency produced an important decrease in reflectance values between 500 ...
Chloroplast functionality has a positive effect on nitric oxide level in soybean cotyledons
(Elsevier Masson, 2013-05)
The subcellular localization of NO generation in soybean cotyledons, and the relationship between NO synthesis and in vivo chloroplast performance were studied. Employing the NO probe 4-aminomethyl-2′,7′-difluorofluorescein ...
The role of cotyledon metabolism in the establishment of quinoa (Chenopodium quinoa) seedlings growing under salinity
(Springer, 2010-01)
A growth chamber experiment was conducted to assess the effect of salinity on emergence, growth, water status, photosynthetic pigments, osmolyte accumulation, and ionic content of quinoa seedlings (Chenopodium quinoa). The ...
Changes in protein fractions, trypsin inhibitor and proteolytic activity in the cotyledons of germinating chickpea
(2001-09-01)
The chickpea seed germination was carried out in 6 days. During the period it was observed a little variation on total nitrogen contents, however the non protein nitrogen was double. A decrease of 19.1 and 20.6% in relation ...
