  The survial rate of graftingbitter gourd on Luffa acutangula rootstock using inversion-grafting method was 92.66%. It was highest among all the grafting treatments. Flowering and fruit-setti ng stage in the grafted plants using Luffa acutangula and Cucurbita ficif olia as rootstock was earlier than that in the non-grafted bitter gourd. The yield of grafted plants on Luffa acutangula and Cucurbita ficifolia was 36.5% and 33.7% higher than that of non-grafted bitter gourd re spectively. The bleeding quan...

  The optimum storage and germination temperature of vet ch spore was 4-5℃ and 20-28℃ respectively. The spore germinati on was inhibited when the temperature was over 30℃ and below 10℃. Gametohyte was tolerant to low temperature of 2℃. The suitable temp erature of fertilization and young sporophyte growth were 20-28℃ and 25 -28℃ respectively. Vetch spore had dormancy which could be breaken by i llumination. The optium illumination of spore propagation was 2000lx. The best medium for spore propagation was the ...

  The phenotypic correlation and path analysis were stud ied with 17 local cultivars of savoy. There were significant or very significant correlation between yield per plant and leaf width,leaf stalk thickness,leafs talk length and leaf length. Their correlation coefficients (r) were 0.6674 ** 0.5479*,0.5478* and 0.4899* respectively. But there was no significant correlation between yield per plant and leafstalk width or leaf number. The res ults of path analysis indicated that leaf width,leaf number and l...
