Thearticle talks about a kind of tree species, Torreya grandis cv. “Merrillii”, whichhas substantial economic value and bares fruits that provide seed-oil nuts. Thesoft, outer layer of the seed is called the sarscotesta. During development, itwas found that the sarcotesta remained green but, there is little informationon its photosynthetic organs.
The purpose of this study was to study thepossible photosynthetic mechanisms in the seed and the rate at which eachmechanism goes through the stages of photosynthesis; and to assess the role of seedlight energy in dry matter accumulation and oil synthesis in seeds.Theresearchers used nine Torreya grandis cv. “Merrillii” trees which weremaintained with standard fertilization, irrigation, and pest control practicescommended for the species. The growth of the Torreya flowers and seeds tookapproximately 2 years. There were a total of 4 Torreya trees sampled and allseeds and leaves that were picked were about the same size. The researchersdetermined that the seed color, dimensions, and weight all had their own phasesduring the growth process.Theresults concluded that photosynthesis is important.
The seed photosynthesis wasmost active during the first stage of seed development. The researchers foundthat the soft, outer layer of the seed (sarscotesta) balanced itself betweennitrogen substances, the second stage of photosynthesis (PSII), rubisco action,and chlorophyll (a+b). It was also found that the leaves of the Torreya hadhigher levels of light energy activity than that of the seeds during the PSII. Thisarticle relates to what I have studied about photosynthesis. It is defined asthe progression by which green plants use sunlight to produce foods from carbondioxide and water.
In plants this generally involves the green pigmentchlorophyll and produces oxygen as a result. I am very interested in motherEarth and how her plants grow and reproduce. I’ve always loved the topic ofphotosynthesis and when searching for an article to read I even stumbled upon aplant that I haven’t heard of.
This assignment was a gold mine for me,personally.
