Chlorophyll Degradation and Formation of Colorless Chlorophyll Derivatives during Soybean (Glycine max L. Merill) Seed Maturation
(AMER CHEMICAL SOC, 2009)
The natural chlorophyll degradation results in noncolored chlorophyll catabolites (NCCs), but there are controversies if these are the final products. The formation and degradation of NCCs during soybean seed (Glycine max ...
PARAMETERS FOR THE STANDARDIZATION OF CHLOROPHYLL AND ASSESSMENT OF PS II QUANTUM EFFICIENCY FOR AVOCADO (Persea americana Mill)
(Univ Federal Uberlandia, 2017-07-01)
The standard physiological parameters for assessing stress physiology, of plants, such as chlorophyll index and photosystem II fluorescence, are essential for measuring reactions of plants to stress conditions. To help ...

Anatomical and physiological aspects of cucumber graft
(2018-01-08)
The grafting of two cucumber scions [Cucumis sativus L.]—Taiko hybrid and Tsuyoi hybrid— onto a Tropical hybrid pumpkin rootstock (Cucurbita moschato L.) was studied. The study was conducted in a greenhouse. Plants grafted ...
The nitrogen sufficiency index underlying estimates of nitrogen fertilization requirements of common beanUso do índice de suficiência de nitrogênio na estimativa da necessidade de adubação nitrogenada em feijoeiro
(Sociedade Brasileira de Ciência do Solo, 2012)
Chlorophyll determination with a portable chlorophyll meter can indicate the period of highest N demand of plants and whether sidedressing is required or not. In this sense, defining the optimal timing of N application to ...
ESTIMATE OF THE GRAIN YIELD OF OATS CULTIVATED UNDER IRRIGATION LEVELS USING CHLOROPHYLL METER
(Faema-fac Educacao & Meio Ambiente, 2018-07-01)
The use of indirect measures of vegetation in agriculture, associated with models, is an efficient way of estimating crop productivity. The objective of this study was to verify the accuracy of models to estimate the yield ...
