The in ̄uence of four day/night temperature combinations (18/12, 25/12, 25/22, 30/22) on plant growth and fruit quality of `Earliglow' and `Kent' strawberry (Fragaria ananassa Duch.) were studied. The optimum day/night temperatures for leaf and petiole growth was 25/128C, while for roots and fruits it was at 18/128C. For the growth of the whole plant, 25/128C was also the optimum temperature. Fr...

water and nutrient absorption by plants is one of the most conspicuous factors which seriously affect plant productivity. improving physical properties of soilless media and their water retaining capacity can improve plant's nutrient absorption, growth and subsequent yield. in this study, we tried to improve plant nutrient absorption through incorporation of hydrogel into growth media and ...

objective(s):solanum acueastrum dunal.has been shown to have some chemotherapeutic value. leaf and berry water and methanol compounds of s. acueastrum were evaluated for possible antileishmanial activity in vivo on balb/c mice and in vitro against leishmania major promastigotes, amastigotes and vero cells.  materials and methods: dry s. aculeastrum berry and leaf material were extracted in meth...

the purpose of this research was to assess the influence of several orchard systems involving trees trained to different leader numbers on growth, cropping, and fruit quality of two apple cultivars. the study was conducted during 1994-2007 at the fruit experimental station in samotwór, next to wrocław (south-western poland). one-year-old trees of ‘elstar’ and ‘jonagold’ cultivars on the m.9 roo...

The growth and development, from fertilization to maturity, of the fruit of Cocos nucifera var. Nana form pumila and its components, were studied in terms of dry matter accumulation. The development of the fruit showed an approximately sigmoidal pattern with a substantial linear phase during which most of the increase in dry weight occurred. During the linear phase of growth the rate of dry mat...

Peroxidase (EC 1.11.1.7)-mediated stiffening of cell walls within the fruit skin of tomato is hypothesized to regulate fruit growth. However, to date, there is no experimental evidence demonstrating that peroxidase affects the mechanical properties of skin tissue. Here, the mechanical properties of skin strips excised from a range of fruits at different ages were determined using an 'Instron' u...

We investigated crop load and water stress effects on diurnal stem extension growth of field-grown peach (Prunus persica (L.) Batsch) trees. Neither the presence of fruit nor reduced irrigation significantly altered the timing of diurnal fluctuations in stem growth rate. Stems with subtending fruit had significantly reduced growth compared to stems with no subtending fruit. Crop load had no sig...
