This is the first report of the ultrastructure of the stigma and style during and after anthesis in Helianthus annuus L. using light and transmission electron microscopy. The stigma is bifid with unicellular papillae. There is no secretion of lipids, carbohydrates or proteins at anthesis. The style is semisolid in the upper portion, closer to the stigma, and becomes solid below. Ultrastructural...

This study aimed to assess the chemical responses of forage watermelon fruit at different maturity stages or storage lengths, performing two experimental tests. In first test, four were assessed: 30, 45, 60, and 75 days after anthesis, with replicates. second fruits maintained under three lengths: T1D (harvest day), T3M (3 months harvest), T6M (6 eight Experimental design was completely randomi...

A method is described whereby amyloplasts from immature barley (Hordeum distichum L.) endosperm could be separated into two populations of large and small amyloplasts at all stages of development. The small amyloplasts had more amylopectin than the large at early stages, but by 60 days after anthesis, the large had the greater proportion of amylopectin. Starch synthetase activity was associated...

Winter wheat production is threatened by drought stress under rainfed conditions; thus, screening high- and stable-yielding varieties to ensure the sustainable development of food security in Huang-Huai-Hai Plain (HHHP) vital. In this research, four-year field experiments with twelve winter were conducted during wheat-growing seasons between 2016 2020 order to: (1) screen conditions, (2) invest...

concinciding of wheat growth in post-anthesis period by water deficiency can result in reduction of current photosynthesis. in this circumstance stem-stored carbohydrate from pre-anthesis period had an important role in supporting assimilates for growing grain. an experiment was conducted in 2007-8 in experimental farm of arsanjan islamic azad university, in order to investigation the quantity ...

Winter wheat is threatened by drought in the Huang-Huai-Hai Plain of China, thus, effective water-saving irrigation practices are urgently required to maintain its high winter wheat production. This study was conducted from 2012 to 2014 to determine how supplemental irrigation (SI) affected soil moisture, photosynthesis, and dry matter (DM) production of winter wheat by measuring the moisture i...
