Studie on the yield physiology of gybrid rice. 1.Assimilate production of photoinsensitive strains in the mid-crop season
No full textHybrid rice strains Tainung Sen Hybrid (TNSH) 2, 6 and 10 and check variety Taichung Sen 10 (TCS 10) were transplanted in late May of 1989 to study characters related to photoassimilate production when cultured as a mid-season crop. Experimental results revealed active vegetable growth for all the rice materials tested as leaf area was over 6 at heading. Area of flag and second leaves consisted of more than 45% of total leaf area for the 3 hybrid strains while the value for TCS 10 was only 34%, indicating different geometric distribution of leaves within the canopy. Crop growth rate (CGR) was highest during the period from maximum tillering to heading, ranging from 186 to 240kg/ha.day. CGR of this period was higher for TNSH 2 and 6 than for TNSH 10 and TCS 10. Therefore, the former 2 hybrids exhibited higher dry matter production at heading. On the contrary, CGR was higher for TNSH 10 and TCS 10 during grain-filling, and hence possessing a more uniform growth rate throughout the whole growth course. Dry matter production after heading accounted for only 10-30% of final dry weight of the rice plant. The low ability of photoassimilate production resulted in low panicle weight. Comparison among rice variety/strains indicated that CGR of panicle during grain-filling was, respectively, 1.83 and 2.64 times higher than CGR of whole plant during the same period, suggesting an imbalance relationship between production and demand of assimilates. Although corresponding values for TNSH 10 and TCS 10 were lower (1.25 and 1.31, respectively), it also implied the development of panicle after heading depended heavily on the redistributed assimilate from preheading storge. Experimental results showed that although the leaves of hybrid strains possessed high leaf area, specific leaf weight and N content (over 1.50 g/m2) at heading, they failed to produce efficiently enough assimilates to support the needs of panicle development. This phenomenon was particularly true for TNSH 2 and 6, and was attributed to as one of the major causes of low yielding performance. As vegetative growth of hybrid strains in the mid-crop was considered over-active, a lower planting density was also suggested
Space-Time Trellis and Space-Time Block Coding Versus Adaptive Modulation and Coding Aided OFDM for Wideband Channels
No full textAbstract—The achievable performance of channel coded spacetime trellis (STT) codes and space-time block (STB) codes transmitted over wideband channels is studied in the context of schemes having an effective throughput of 2 bits/symbol (BPS) and 3 BPS. At high implementational complexities, the best performance was typically provided by Alamouti’s unity-rate G2 code in both the 2-BPS and 3-BPS scenarios. However, if a low complexity implementation is sought, the 3-BPS 8PSK space-time trellis code outperfoms the G2 code. The G2 space-time block code is also combined with symbol-by-symbol adaptive orthogonal frequency division multiplex (AOFDM) modems and turbo convolutional channel codecs for enhancing the system’s performance. It was concluded that upon exploiting the diversity effect of the G2 space-time block code, the channel-induced fading effects are mitigated, and therefore, the benefits of adaptive modulation erode. In other words, once the time- and frequency-domain fades of the wideband channel have been counteracted by the diversity-aided G2 code, the benefits of adaptive modulation erode, and hence, it is sufficient to employ fixed-mode modems. Therefore, the low-complexity approach of mitigating the effects of fading can be viewed as employing a single-transmitter, single-receiver-based AOFDM modem. By contrast, it is sufficient to employ fixed-mode OFDM modems when the added complexity of a two-transmitter G2 scheme is affordable
