    (University of Agricultural Sciences, Bangalore, 2018-08-01) SHIVANAND KUMBAR; VENKATESHA MURTHY, P.
    A study was conducted to find out the effect of microbial inoculants on growth of papaya seedlings under polyhouse condition at UAS, Bengaluru during the year 2017-18. Papaya (Carica papaya L.) is an important fruit crop of tropical world and has long been known as wonder fruit of the tropics. It belongs to the family Caricaceae. To improve the seedling quality, a nursery study was conducted to select the suitable bio-inoculants for growth of papaya seedlings. The bio-inoculants such as Glomus fasciculatum, Pseudomonas fluorescence, Azotobacter chroococcum, Azospirillum lipoferum were isolated and inoculated individually and in combinations. Seedlings were kept at 120 days under polyhouse conditions. Among them, early seed germination (5 days) in treatment with Glomus fasciculatum + Pseudomonas fluorescence + Azotobacter chroococcum + Azospirillum lipoferum (T11) was recorded. This treatment also influenced most of the growth parameters positively, Viz. higher plant height (63.21 cm at 120 DAS), higher number of leaves (15.35 at 120 DAS), more leaf area ( 72.37 cm2 at 120 DAS), more number of roots per plant (16.33), higher root length (15.67 cm), higher fresh (73.83 g) and dry weight (3.83 g) of roots per plant and highest chlorophyll content (22.4 mg). Thus, it can be concluded that, the combined inoculation of bio-inoculants are beneficial for increasing the growth and quality seedling production in papaya Cv. Red Lady.

    STUDIES ON IN VITRO REGENERATION IN LIME (Citrus aurantifolia) AND MANDARIN (Citrus reticulata)
    (University of Agricultural Sciences, Bangalore, 2018-08-01) KHALID, AKHUNDZADA; SATHYANARAYANA, B.N.
    Citrus species are propagated by both sexual and asexual methods. The present study was conducted to investigate into the in vitro responses of lime and mandarin in particular reference to seed. Sterilants such as alcohol, sodium hypochlorite, mercuric chloride were used. However, repeated trials with modiefied procedures done over a period of around six months, aseptic cultureof leaf and nodal segments could not be obtained. In studies on identification of endophytic microorganisms, revealed the presence of Colletotrichum spp. Hence, seeds were used as explant. In lime, highest percentage of germination, increased shoot length, increased number of leaves and increased root length was obtained when seeds were cultured on MS media containing BAP at 3 mg/l and BAP + NAA at 5 + 0.5 mg/l. In mandarin media containing Kinetin at 5 mg/l and Kinetin + NAA at 3 + 0.1 mg/l, increased values of germination percentage and other growth parameters were obtained. Callusing from seeds during germination could be found in media containing BAP at 1 mg/l. Organogenesis could be induced when the calli were cultured on media containing Kinetin at 1 mg/l. When auxins were supplied at a higher concentrations above 1 mg/l irrespective of cytokinin content, a detrimental effect on seed germination and callus initiation was observed. When nodal, internodal and cotyledonary segments were cultured, in basal salts media and in media containing 1 mg/l of BAP, organogenic responses were obtained. Increased shoot proliferation and enhanced growth parameters such as increased, number of shoots, number of leaves and shoot length, was obtained in particular with BA 1 mg/l + NAA 0.1 mg/l.

    CONSERVATION OF GEOGRAPHICAL INDICATION (GI) TAGGED JASMINES THROUGH TISSUE CULTURE
    (UNIVERSITY OF AGRICULTURAL SCIENCES, GKVK BENGALURU, 2019-10-31) RANGANATHA, G. J.; Nirmala, K. S.
    Karnataka registered three jasmines cultivars in geographical indication registry during the year 2006. They are Mysore mallige (Jasminum azoricum L. syn. J. trifoliatum Moench), Udupi mallige (J. sambac (L.) Aiton) and Hadagali mallige (J. auriculatum Vahl), flowers of each of these species are unique in their fragrance. The present study aimed to conserve these species through slow growth storage, by direct and indirect organogenesis. In indirect organogenesis, the response of leaf explants for callus initiation was 100% in all the three species, early callus initiation being observed in MS medium supplemented with 2,4-D at 0.2 mg L-1 after 10, 11.6 and 9 days in Udupi mallige, Hadagali mallige and Mysore mallige respectively. Callus intensity was highest in the medium supplemented with 2,4-D at 0.4 mg L-1 : Udupi mallige (Very good), Hadagali mallige (Good), and Mysore mallige (Good). Callus was friable and white (Udupi mallige), brownish (Hadagali mallige) and creamish green (Mysore mallige). However, no organogenesis was observed when cultured on benzyl adenine (BA), kinetin (KN), naphthalin acetic acid (NAA) and in their combinations. The auxins (NAA (0.25 mg L-1 to 0.5 mg L-1 ) , 2,4-D (0.2 mg L-1 to 0.4 mg L-1 ) and cytokinin (Kinetin (2.0 mg L-1 to 6.0 mg L-1 ) , BA (2.0 mg L-1 to 6.0 mg L-1 ) treated cultures showed browning of callus after 60 days of culturing. For direct regeneration, shoot tips of all the three species were cultured on MS medium containing BA, KN, NAA and their combinations which resulted in only callus production. In none of the three species multiple shoots were noticed. Slow growth storage method adopted to conserve the callus, with 1.0 mg L-1 to7.5 mg L-1 ancymidol and 0.1 mg L-1 to 2.0 mg L-1 abscisic acid on half MS media indicated that the ancymidol treated cultures do not show any change even after 75 days, but abscisic acid treated cultures turned brown from white (Udupi mallige), brownish (Hadagali mallige) and creamish green (Mysore mallige) after 60 days.

    COMPARATIVE STUDY OF ARECOLINE CONTENT IN Areca catechu Linn. AT VARIOUS STAGES OF MATURITY IN DIFFERENT AGROCLIMATIC ZONES OF KARNATAKA
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2019-09-14) VAIDEHI VIDHANCHANDRA PAI; VASUNDHARA, M.
    Arecanut is associated with tradition and used in different cultural, social, and religious ceremonies. Arecoline is primary active ingredient in the areca nut and has wide range of pharmacological activities. Development of a simple and rapid method to determine the content of arecoline in areca nut and its extracts before usage in any form of consumption is needed. An experiment was conducted at Department of Horticulture, UAS, GKVK to study the arecoline content in Areca catechu Linn. at various stages of maturity in different agroclimatic zones of Karnataka. Arecanut samples were collected from four agroclimatic zones (Zone - 4, 7, 9 and 10) at three different stages of maturity (5-6,7-8 and 9-10 months). The interaction effect of agro-climatic zones and stage of maturity as well as the individual effects of the two on the total alkaloid content, arecoline content in the nuts and percentage of arecoline was found to be significant. Among the agro-climatic zones, significantly high total alkaloid content (6.77 mg g-1) was recorded from Zone-7 and significantly high arecoline content (12.59 mg g-1) was recorded from Zone-10. Significantly high percentage arecoline in total alkaloids (38.141%) was noted in Zone-9. Mature nuts (9-10 month old) had higher total alkaloid content (9.11 mg g-1), arecoline content (4.84 mg g-1) and higher arecoline percentage of total alkaloids (53.896 %). Significantly high amount of total alkaloids (12.28 mg g-1) , arecoline content in the nuts (6.71 mg g-1) were recorded from mature nuts from Zone-10. However, the percentage arecoline in total alkaloids (55.44 %) was significantly in high mature nuts from Zone-9. Thus it was concluded that both agroclimatic zone and stage of maturity as well as their interaction impacted the arecoline content in arecanut.

    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2019-08-23) SHARUKHKHAN; SHARUKHKHAN; VENKATESHA, M.; VENKATESHA, M.
    The present study was conducted to know the influence of vermicompost in combination with Microbial Consortium on growth, yield and quality of Chrysanthemum (Dendranthema grandiflora L.) cv. Marigold was carried out at Precision Farming Development Centre, Department of Horticulture, Gandhi Krishi Vigyana Kendra, University of Agricultural Sciences, Bengaluru during kharif season of 2018-19 and this experiment was laid out with a design of Randomised Complete Block Design (RCBD) with 10 treatment with 3 replication combination. The treatments were imposed with combination of organic, inorganic and biofertilizers with a spacing of 45cm x 45cm between the rows and plants. The results of the experiment indicated that, treatment combination with Vermicompost + 50 per cent RDF + AMC (T9) recorded significantly highest plant height, more number of branches, plant spread and yield attributes such as flower diameter, number of flowers per plant, average flower weight, flower yield per plant and flower yield per hectare. The soil sample analysed from the combination treatment (T9) showed higher available nutrients (N, P2O5 and K2O) and their uptake by plants. The same treatment (T9) registered significantly superior quality parameters such as flower diameter and shelf life of the flower. The economic analysis clearly indicated that net returns obtained per hectare and B:C ratio (1.98) was highest in the plots imposed with Vermicompost + 50 per cent recommended dose of fertilizers + AMC (T9) and can be used for commercial chrysanthemum production with more profitable.
