Item Effect of phased october plantings and plant density on growth and yield of cabbage var. golden acre(Kerala Agricultural University, 1980) Vasantha Kumar, K; Indrasenan, G; Gopikumar, K; Balasubramaniyan, P PItem Microflora of preserved squashes(Kerala Agricultural University, 1972) Balagopalan, C; Indrasenan, G; Varadarajan, P; Balakrishnan, S; Nair, E V GItem Mode of survival of Pseudomonas Solanacearum (Smith) Smith causing bacterial wilt of ginger (Zingiber Officinale Rose.)(Kerala Agricultural University, 1981) Indrasenan, G; Sreekumar, V; James Mathew; Mammen, M KItem New graminaceous weed hosts of ephelis oryzae syd. in Wynad(Kerala Agricultural University, 1983) Indrasenan, G; Mammen, M KItem On the chemical control of 'udbatta' disease of rice incited by Ephelis Oryzae Sydow(Kerala Agricultural University, 1981) Indrasenan, G; Jim Thomas; Sreekumar, V; Mammen, M KItem Performance of coorg mandarin (Citrus reticulata blanco) on different root stocks under the agroclimatic conditions of Wynad(Kerala Agricultural University, 1982) Indrasenan, G; Mammen, M KPerformance of six promising rootstocks of mandarin under the climatic conditions of Wynad was evaluated for the first five years after planting. The data presented in this paper indicated that Carrizo Citrange, Rough lemon and Troyer Citrange had given better performance than others in respect of most of the parameters understudy. Rangpur lime and Cleopatra mandarin were also performed satisfactorily whereas Trifoliate orange had given poor performance. However, consistent good performance was not seen in any of the rootstocks understudy presumably due to the variability of growth pattern as influenced by the rootstocks during the early years of growth. General observation revealed that Trifoliate orange exhibited retarded growth during the early stages and was comparatively free from chlorosis.Item Physiology of parasitism of Pythium Aphanidermatum (Edson) fitz. inciting soft-rot of ginger(Zingiber officinale rose)(Kerala Agricultural University, 1982) Indrasenan, G; Paily, P VA study on production of pectic enzymes in five liquid media was made. Pythium aphanidermatum (Edson) Fitz. was found capable of elaborating various pectic enzymes in vitro and in vivo, Estimation of pectic enzymes like pectin methyl esterase (PME), exopolygalacturonase (Exo-PG), endopolygalacturonase (Endo-PG) polygalacturonase transeliminase (PGTE) and macerating activity on potato discs were done in five liquid media on four different days and observed that the rate of production of these enzymes by P. aphanidermatum varied with different media and age of the culture, the maximum production being noted in Conn's medium on the 3rd day. P.aphanidetmatum(Edson)Fitz. was found to produce various pectic enzymes as judged by the in vitro and in vivo studies which play a predominant role in bringing about the tissue degradation and the eventual pathogenesis on the host.Item Reaction of different types of ginger to bacterial wilt caused by Pseudomonas solanacearum (Smith) Smith(Kerala Agricultural University, 1982) Indrasenan, G; Vasantha Kumar, K; James Mathew; Mammen, M KItem Resistance of some rice varieties to 'udbatta' disease in Wynad(Kerala Agricultural University, 1982) Indrasenan, G; Sreekumar, V; Jim Thomas; Mammen, M KItem Rhizosphere and non-rhizosphere mycoflora of certain fruit plants in Wynad(Kerala Agricultural University, 1974) Bhavani Devi, S; Balagopal, C; Indrasenan, G; Varadarajan Nair, PItem Studies on the soft rot of ginger (Zingiber officinale rose) caused by Pythium aphanidermatum (Edson) Fitz.(Kerala Agricultural University, 1973) Indrasenan, G; Paily, P VItem Varietal reactions of ginger (Zingiber Officinale R.) towards soft rot caused by Pythium aphanidermatum (edson) fetz(Kerala Agricultural University, 1974) Balagopal, C; Bhavani Devi, S; Indrasenan, G; Wilson, K IArtificial inoculation of 22 varieties of ginger in the field with P. aphanidermatum showed that none of the varieties tested was resistant to infection. Only two varieties namely, Nadiya and Narasapattam were moderately resistant. Six varieties were moderately susceptible and twelve varieties were susceptible. The varieties Bajpai and Seirra-leone were highly susceptible to the disease.Item Wilt of Vanilla planifolia A(Kerala Agricultural University, 1974) Balagopal, C; Indrasenan, G; Bhavani Devi, S; Sukumara Varma, A
