In the present study, trials were done to investigate the influence of supplementing Murashige and Skoog’s culture medium with mammalian sex hormones (progesterone, estrogen, testosterone, human chorionic gonadotropin (HCG) and anabolic steroids on enhancing regeneration of Balanites aegyptiaca L., in vitro. For this purpose, nodal segment explants which were excised from in vitro grown plantlets (5-6 weeks old) were cultured on MS medium supplemented with 0.5 mg/L BAP in addition to progesterone, estrogen, testosterone, HCG and anabolic steroids (1.0, 3.0 and 5.0 mg/L each). For rooting, the regenerated shoots were cultured on half strength, hormone-free MS medium (as a control) or supplemented with 1.0 mg/L anabolic steroids alone or combined with β-cyclodextrin (10 and 20mg/L) and/or IBA (1.0 and 2.0 mg/L). Results of the present study have revealed that impregnating the culture medium with mammalian sex hormones (MSHs) had, in the great majority, significant positive effects on number of shoots per explant, shoot length, number of leaves per single shoot, and leaf area of Balanites aegyptiaca after 5 weeks of incubation. For example, impregnating the culture medium with 5.0 mg/L testosterone had resulted in the maximum shoot length, number of leaves and leaf area (15.33cm, 29 and 2.78cmrespectively). The highest significant shoots number per explant reached up 4.0using 1.0 mg/L testosterone. On other hand, the least significant number of shoots/nodal segment, shoot length, number of leaves and mean leaf area were(1.0, 1.93cm, 3.67, and 0.1cmrespectively)in response to treatment with 5.0 mg/L HCG. The results obtained showed also that half strength MS medium supplemented with 1.0 mg/L anabolic steroid hormone with or without 1.0 mg/L IBA had the highest significant rooting percentage (75%) and number of rootlets per shoot (5.67). The highest significant root length (5.50cm) was obtained when regenerants were cultured on half strength MS medium supplemented with 1.0 mg/L anabolic steroids hormones combined with 20.0 mg/l βcyclodextrin. The obtained regenerants were easily acclimatized within 4 weeks and transferred to greenhouse with a survival percentage of 95%. The results obtained in this study may indicate the promising future role that mammalian sex hormones (MSHs) can play in enhancement of shoot and root morphogenesis in vitro

An experiment was conducted in agriculture field, Karaikal during the season of JuneSeptember to observe the efficacy of isolated bacterial endophytes from the roots of bhendi as microbial inoculants in seeds on growth, yield and some biochemical constitutions of bhendi cv. Arkaanamika [Abelmoschus esculentus (L.) Moench] and the results revealed that the height of plant, number of branches, number of leaves, number of flowers, number of fruits, fruit weight, fruit length, fruit diameter and yield/plot were recorded maximum in T7and proved that the application of microbial inoculants and their combinations with inorganic fertilizers significantly influenced the growth, yield, quality and biochemical contents of bhendi. The combined application rates of 75% Chemical fertilizer with Azospirillum braziliense and Pseudomonas fluorescens gave the best performance of bhendi compared to other treatments. From the results, microbial inoculants willreduce the farmer’s budget for crop fertilization and inclusion of organic fertilizer in the combination will surely ensure production of crop under a less polluted environment.

Object of study to improve semen preserve ability through the use of trehalose sugar as extender additive expressed in frozen semen and education effect steps of freezing on sperm properties. The research trail was carried on the semen samples collected from 4 bulls through a period of 16 weeks, were diluted with Tris-based extender containing different Trehalose concentrations (viz. 50, 100, 150,200) mM and control, evaluated for semen characteristics at steps of freezing (after dilution, after cooling and Post-Thawing). Results clearly indicated that, 100mM Trehalose group had significantly (P<0.05) higher individual motility in comparison to the 50Mm, 150mM, 200Mm and control group. Moreover, the sperm dead and abnormality was significantly (P<0.05) lower, when compared to the control group. The freezing process negatively affects (P < 0.05) the sperm parameters (individual motility, dead and abnormality), but the current study revealed that this effects were changes from treatment to another’s, it means there is interaction between effect steps of freezing and addition trehalose to Tris diluents of bull spermatozoa, however, overall, this effect was lower when the 100mM trehalose was added to this diluents. Conclussion: The addition of 100 Mm trehalose to TFEG diluents had their benefits on freezing-thawing bull semen. A step of freezing process was detrimental to bull sperm properties, but this effect was less when adding 100Mm trehalose to the diluted.

The tomato is a major vegetable crop that has achieve tremendous popularity over the last century. It is grown in practically every country of the world – in outdoor fields, greenhouses and net houses. The tomato plant is very versatile and the crop can be divided into two categories; fresh market tomatoes, which we are concerned with and processing tomatoes, which are grown only outdoors for the canning industry and mechanically harvested. In both cases, world production and consumption has grown quite rapidly over the past 25 years. Tomatoes can make people healthier and decrease the risk of conditions such as cancer, osteoporosis and cardiovascular disease. People who ate tomatoes regularly have a reduced risk of contracting cancer diseases such as lung, prostate, stomach, cervical, breast, oral, colorectal, esophageal, pancreatic, and many other types of cancer. Some studies show that tomatoes and garlic should be taken together at the same time to have its cancer preventive effects. Whatever it is, we really do not know how or why tomatoes work against cancers. We believe that lycopene and the newly discovered bioflavonoids in tomatoes are responsible as cancer fighting agents. Not only raw tomatoes but also cooked or processed tomato products such as ketchup, sauce, and paste, are counted as good sources of cancer prevention. Tomato is also good for liver health. Tomatoes, aside from being tasty, are very healthy as they are a good source of vitamins A and C. Vitamin A is important for bone growth, cell division and differentiation, for helping in the regulation of immune system and maintaining surface linings of eyes, respiratory, urinary and intestinal tracts. Vitamin C is important in forming collagen, a protein that gives structures to bones, cartilage, muscle and blood vessels. It also helps maintain capillaries, bones and teeth and aids in the absorption of iron.

Numbers of estrus synchronization programmes are available in cattle based on the use of various hormones like progesterone, prostaglandin F2α and their various combinations with other hormones like estrogen and Gonadotrophin Releasing hormone (GnRH). Selection of appropriate estrus synchronization protocol should be made on the basis of management capabilities and expectations of the farmer. Synchronization of oestrus can be accomplished with the injection of prostaglandin F2α alone, but it needs proper detection of the ovarian status of the cows as prostaglandin F2α is active in only functional corpus luteum in between 8 to 17 days of estrous cycle. Progesterone may reduce fertility up to 14 percent, but short time progesterone exposure (less than 14 days) is beneficial. Addition of GnRH in the Progesterone or Prostaglandin based synchronization programme is helpful for more synchrony in estrus as GnRH may be helpful to synchronize the oestrous cycle in delayed pubertal heifers and post partum cows (Post partum anoestrum) and further a single, timed artificial insemination is possible with this method. New methods of synchronizing estrus in which the GnRH-PG protocol is preceded by progesterone treatment offer effective synchronization of estrus with high fertility.

Plant based pesticides are known as phytopesticides. Phytopesticide formulations offer a more eco-friendly approach to Insect Pest Management than chemical pesticides. The biological compounds present in these formulations have several biological activities against insect pests. In the present work, an attempt has been made to study the antifeedant activity of Gliricidia sepium leaf extracts using three solvents, i.e; petroleum ether, ethyl acetate and methanol against third instar larvae of Helicoverpa armigera. All extracts exhibited as significant antifeedant activity at LC50. Methanol extract deterred feeding potential of the insect larvae by 62.38% at 1000 ppm, followed by ethyl acetate (46.67%) and petroleum ether (40.37%). Hence this naturally occurring plant extracts could be useful for managing the Helicoverpa armigera population.
