Flowering is a critical step in fructification. No flowers mean no fruit, and when flower number is low crop load may be limited by the number of flowers formed. In most cases, however, citrus trees form a number of flowers exceedingly higher than the final number of fruits harvested, which usually is a very low percentage of the initial flower number. As in other species which form a large amo...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
German chamomile (Matricaria chamomilla L.) is cultivated in many countries because of its wide-spread uses in pharmaceutical, cosmetics and food industries. In order to investigate the effects of different soil properties on the agro-morphological characteristics, essential oil and chamazulene content of German chamomile, a pot experiment was carried out in a Randomized Complete Block Design (...
How different organs are formed from small sets of undifferentiated precursor cells is a key question in developmental biology. To understand the molecular mechanisms underlying organ specification in plants, we studied the function of the homeotic selector genes APETALA3 (AP3) and PISTILLATA (PI), which control the formation of petals and stamens during Arabidopsis flower development. To this ...
this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...
tuberose cut flower is considered one of the most important cut flowers from the viewpoint of production and export. the failure of developing buds into open ones and the abscission of floret are two of the common problems in the postharvest of tuberose cut flower that diminishes its longevity and therefore its market quality. this research was conducted to investigate the effect of 2,4-d sucro...
The interactions between vernalization and photoperiodic effects on the flowering of 12 turnip varieties were examined under controlled environment. Seedlings of all varieties bolted and flowered under a long-day condition of 24 h day-length (LD) when the germinated seeds had been pre-exposed to low temperature at 3 •Ž (LT) for 30 days. Under the LD condition, the ratio of flower formation of a...
In order to elucidate the correlation of temperature and the effect of gibberellin spray on the development of flower-buds in Cryptomeria japonica cultivar Kumotooshi, experiments were done in controlled environmental condition during 1970-1971. The following points were observed: 1. The male flower-buds were formed maximum in the temperature range of 25°C-30°C and their formation decreased wit...
Extended Abstract Introduction and Objective: Medicinal plants have many applications in the treatment of humans, among which chamomile is one of the most valuable and widely used medicinal plants in the world. One of the most important breeding programs is the recognition of genetic diversity for the initial evaluation of plant masses. For this purpose, a study of genetic diversity and classi...
Most varieties of sweet potatoes (Ipomoesa batatas Lam.) bloom fairly readily under proper environmental conditions. So far as the writer knows, however, there is no report in the literature of a first-hand observation of blossom formation in any variety of the Jersey group, a group defined by THOMPSON and BEATTIE (1). Physiologists, formulating theories of the fundamental mechanisms of flower ...
