The Floral Development, Structure Of The Stamens And Staminodes In The Monoecious Pseuduvaria trimera (Annonaceae)

Flowering plants exhibit spectacular sexual diversity .The formation of unisexual flowers is thought to promote outcrossing , prevent inbreeding depression , and enhance genetic variability .And the morphological and anatomical features of its mature stamens and staminodes were investigated by Yang and Xu . The data suggest that staminate flower...
　　Flowering plants exhibit spectacular sexual diversity. The formation of unisexual flowers is thought to promote outcrossing, prevent inbreeding depression, and enhance genetic variability. The Annonaceae are one of the largest families of Magnoliales. The family comprises diverse unisexuality. The comparative development of staminate and pi...

The Comparison Of Synandrium Structure And Development In Three Species From The Myristicaceae

To clarify the origin of the synandrium , comparative development and anatomy of the synandria of M . fragrans , H . pandurifolia , and H . tetratepala were investigated by Yang and Xu . Three types of synandrium origin were observed : in M . fragrans .Anatomy of staminate flower buds in Horsfieldia pandurifolia during the meiotic stage of micro...
　　Myristicaceae is classified in the Magnoliales, an order of basal angiosperms. The plants of this family are dioecious and the flowers are described as unisexual with a single perianth. The male flowers are characterized by the presence of a distinctive androecium composed of a sterile column, and longitudinally oriented anthers fused to th...

Urban farming

By 2040 , Chinese cities will house a billion residents , and the need to provide fresh food for this large population will become a greater challenge .Urban development reduces arable land for traditional agriculture while urban industrialization pushes clean growing areas further away from urban centers .In 2016 , PhD student LIU Ting and coll... By 2040, Chinese cities will house a billion residents, and the need to provide fresh food for this large population will become a greater challenge. Urban development reduces arable land for traditional agriculture while urban industrialization pushes clean growing areas further away from urban centers. Hence, not only is China facing the prosp...

Cooking reduced the bioaccessibility of toxic metals in rice and vegetables

There is a growing concern about heavy or toxic metals pollution in foodcrops , since dietary intake is considered to be one of the major routes of metal ( loid ) exposure to humans .Cadmium ( Cd ) , lead ( Pb ) and Arsenic ( As ) are among the most common toxic heavy metals .Therefore , food safety has emerged as an urgent issue and there is a ... There is a growing concern about heavy or toxic metals pollution in foodcrops, since dietary intake is considered to be one of the major routes of metal(loid) exposure to humans. Cadmium (Cd), lead (Pb) and Arsenic (As) are among the most common toxic heavy metals. The excessive levels of these metals in foodcrops are associated with etiology of...

IABG INTERNATIONAL CONFERENCE ON PLANT CONSERVATION IN CHINA

China is one of the richest countries in plant biodiversity in the world and also has a high level of endemism. However, plant diversity in China is increasingly threatened due to rapid industrialization, extensive urbanization, and explosive economic growth. Twenty percent of China's total higher plants are threatened with extinction. As a r...
