    Morphology of the inflorescence and fruit in jack (Artocarpus Heterophyllus Lam.)
    (Kerala Agricultural University, 1995) Tessy Joseph; Kumaran, K
    The iiiflorescence in jack is a catkin. The individual flowers are radially arranged on a lleshy peduncle. The perianth tubes of male flowers are free from each other, while those of female (lowers are fused in the middle region. Androecium consisted of a single stamen with a hasifixed four celled anther. Gynoecium consisted of a white waxy clavate stigma, a slender style and a unicelled ovary with a solitary ovule inside, attached by marginal placentation. The female catkin after pollination developed into a large composite fruit (sorosis) which is a 'false fruit', with the persistent perianth forming the hulk of the f r u i t . The 'tnie fruit' resembled an achene. Except for the texture of the flakes after ripening, the two types studied had the same morphological features; the 'koo/.ha' with soft mushy Hakes an 'varikka' with crisp hard flames.

    Fruit set, fruit development and eruit drop in hard and soft flaked types of jack (Artocarpus heterophyllus Lam.)
    (Kerala Agricultural University, 1996) Tessy Joseph; Kumaran, K
    Studies on fruit set, fruit drop and fruit development in ' Varikka' and ' Koozha' types of jack (Artocarpus heteropkylhis Lam.) have indicated that the fruit set under natural condition was 83.335?,. The post-set drop ranged from 3040% in the two types studied. The peak period of drop was observed between the 60th and 80th day after emergence of the catkin. The time required for full development of fruit ranged from 100 to 138 days. Growth of fruit showed a sigmoid pattern, the rate being rapid up to the first 80 days and thereafter declined gradually The two types 'Varikka' and 'Koozha' did not vary significantly in any of the above characters.

    Correlation and yield component analysis in greengram (Vigna Radiata L.) in summer rice fallows
    (Kerala Agricultural University, 1996) Kanakamany, M T; Gracy Mathew; Leenakumary Tessy Joseph, S; Tessy Joseph
    Twelve genotypes of greengram were evaluated during summer 1995 in the rice fallows of tiie Regional Agricultural Research Station, Pattambi. WGG 62 was the highest yielder among the genotypes tested. Out of the ten characters studied the number of pods per plant, per day productivity, chlorophyll ' a' and total chlorophyll contents showed positive and significant association with grain yield. Duration of the crop was found to have no direct relation with yield.

    Flowering, floral biology and pollination in hard and soft flaked types of jack (Artocarpus heterophyllus Lam.)
    (Kerala Agricultural University, 1996) Tessy Joseph; Kumaran, K
    Investigations'on the floral characters of "Varikka' and "Koozha' types of jack (Artocarpus heterophyllus Lam.) were conducted at the Agricultural Research Station, Mannuthy, Trichur on 14 mature trees. There was no significant difference between 'Varikka' and 'Koozha' types in respect of any of the characters studied. The pattern of male and female catkin production was found to differ in jack, the former occurred from October to February while the later was confined to only three months starting from late November to February. In a male catkin, anthesis started by 6 a.m. and continued up to 6 p.m. in a day. This pattern continued for 5 to 7 days in a catkin. Anther dehiscence occurred between 6 p.m. and 7 p.m. on the day of its emergence. The sequence of emergence of stigma on the female catkin was highly erratic and continued for 3 to 4 weeks. Complete fading away of the stigma occurred in 21 to 35 days after anthesis started. The chief agent of pollination was found to be wind although certain amount of insect pollination cannot be ruled out.
