tomato plays an important role in providing vitamins and minerals in human nutrition, it has a great potential in exports. as well as it is an important vegetable due to its variety of vitamins, carotene, useful acids, sugar and minerals play an important role in human health. regarding the fact that tomato is one of the most significant products and its consumption is rising up day after day, ...
the use of in vitro potato shoot cultures for protoplast isolation is desirable for consistent protoplast qualities. ethylene build-up in the culture vessels causes problems for leaf growth (e.g. decreasing leaf surface, dry weight and chlorophyll) in shoot culture. fifty to one hundred µm silver thiosulfate (sts) produced a larger leaf area as a source of plant material for protoplast isolatio...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
In order to find out the importance of flag leaf in Hordeum vulgare L. cv. Hordea in some physiologic traits and photosynthetic and leaf senescence-related gene expression, a field experiment was carried out in Warwick University Research Farm, UK, in 2003. For more accuracy and statistical comparison of the calculated means, the experiment was carried out in 4 replicates. Random leaf samples w...
Methods for chlorosis detection and physiological condition monitoring in Vitis vinifera L. through accurate chlorophyll a and b content (Cab) estimation at leaf and canopy levels are presented in this manuscript. A total of 24 vineyards were identified for field and airborne data collection with the Compact Airborne Spectrographic Imager (CASI), the Reflective Optics System Imaging Spectromete...
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
effective microorganisms (em) is a commercial biofertilizer mainly consists of photosynthetic and lactic acid bacteria, yeast and actinomycetes. in order to evaluate the influence of em (0 and %1) and salt stress (0 mm, 50 mm, 100 mm and 150 mm) on the morphophysiological characteristics of pomegranate cv. shishe-kap, a factorial experiment was conducted based on the completely randomized desig...
In order to evaluate the tuber fresh weight and some physiological attributes of Agria potato cultivar in response to water deficit stress and mycorrhiza inoculation, a field trial was conducted as a split plot scheme based on randomized complete block design with three replications at the research site of Islamic Azad University, Tabriz Branch in 2012. Four water levels including: irrigation a...
Water stress is a global crisis and is considered a serious threat for agriculture. Superabsorbent polymers, through improving soil physical conditions, prevent moisture stress in arid and semi-arid areas. To evaluate the effects of a natural superabsorbent (bentonite) and a synthetic superabsorbent (A200) on growth of lettuce, a factorial experiment in a completely randomized design with four ...
tobacco is a salt-sensitive glycophyte crop species. in this work effect of silicone (si) supplementation (1 mm as na2sio3) was studied in nicotiana rustica l. cv. basmas grown hydroponically in growth chamber under control, low (25 mm) and high (75 mm) nacl concentration for two weeks. dry matter production of leaves was depressed by salinity level as low as 25 mm and higher salt concentration...
